Proposed New Technical Committee Name and Scope

1. Replace the current name of the Technical Committee (Technical Committee on Automotive and Marine Service Stations) with the following: “Technical Committee on Motor Fuel Dispensing Facilities and Motor Vehicle Repair Facilities” JUSTIFICATION: First, the current committee name dates back to its inception, when it dealt almost exclusively with traditional retail service stations. It now covers fleet fuel dispensing operations and repair garages (having absorbed the former NFPA 88B, Standard for Repair Garages). The scope of the committee now embraces almost all motor vehicle fuel dispensing operations, except those dealing exclusively with gaseous fuels and major repair facilities, such as fleet and vehicle dealership maintenance operations. YES______ NO______ ABSTAIN______ Reason for “NO” or “ABSTAIN:_____________________________________________________ __ ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________

2. Revise the Technical Committee Scope to read as follows: “This Committee shall have primary responsibility for documents on safeguarding against the fire and explosion hazards associated with the general storage, handling, and dispensing of flammable liquids, and combustible liquids, and gaseous fuels at motor fuel dispensing facilities; automotive and marine service stations, farms;, and isolated construction sites; and with related activities, such as operation, inspection, and maintenance of fuel dispensing and storage systems and components gaseous fuels. This Committee shall have responsibility for the dispensing of gaseous fuels only at facilities where liquid fuels are also dispensed. This committee shall also have primary responsibility for documents on construction, control of fire hazards, ventilation, fire protection, and maintenance of motor vehicle repair facilities garages. Responsible for NFPA 30A, Code for Motor Fuel Dispensing Facilities and Repair Garages.” JUSTIFICATION: These amendments accomplish two objectives. They succinctly and comprehensively describe the subject areas covered by the document(s) under the jurisdiction of this committee. A specific statement is made governing this committee’s limitations with respect to gaseous fueling operations. YES______ NO______ ABSTAIN______ Reason for “NO” or “ABSTAIN:_______________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________

Subject: Joint Task Group on Multiple Fuels Dispensing Stations - NFPA 2 and NFPA 30A

See below for the proposed scope for a joint task group between NFPA 30A and 2 on Multiple Fuels Dispensing Stations. This will be discussed at the upcoming NFPA 30A first draft meeting in October. If you are interested in participating on the task group, please let me (Susan Bershad, staff liaison for NFPA 2), Bob Benedetti (staff liaison for NFPA 30A) or your respective chair know. Please let me know if you have any questions or need additional information. Thanks.

Joint Task Group NFPA 30A/NFPA 2

Multiple Fuels Dispensing Stations Scope: Joint task group between NFPA 30A, Code for Motor Fuel Dispensing Facilities and Repair Garages and NFPA 2, Hydrogen Technologies Code to investigate requirements related to multi‐fuel (traditional gasolines, diesel fuels) combined with alternative fuels (hydrogen) in a retail fueling station setting. Dispensers for hydrogen will be located on the same fueling island as dispensers for traditional fuels. Review current content of both NFPA 30A and NFPA 2. Confirm adequacy of and proper coordination of code requirements in both NFPA 30A and NFPA 2. Develop and submit code change proposals as needed to correct any issues identified.

Attachment No. A7

Public Input No. 39-NFPA 30A-2015 [ Section No. 1.1.3 ]

1.1.3*

This code shall not apply to those motor fuel dispensing facilities where only liquefied petroleum gas(LP-Gas), liquefied natural gas (LNG), or compressed natural gas (CNG), or hydrogen is dispensed asmotor fuel.


NFPA 2, Hydrogen Technologies Code, is not currently recognized in Chapter 1 Administration yet NFPA 2 contains two chapters on hydrogen fueling facilities (i.e. - Chapter 10 – GH2 Vehicle Fueling Facilities; and Chapter 11 – LH2 Fueling Facilities) as well as a chapter on repair garages servicing hydrogen-fueled vehicles (i.e. - Chapter 18 – Repair Garages). These requirements are contained only in NFPA 2 and nowhere else. Previous text in NFPA 52 has been removed. The Standards Council has revised the Scope of NFPA 52 and removed fueling of hydrogen-fuel cell vehicles (FCV). Therefore, fueling requirements for hydrogen are contained in NFPA 2 and the exclusion of section NFPA 30A 1.1.3 should be extended to hydrogen fueling as well as CNG and LPG.

1.1.3*

This code shall not apply to those motor fuel dispensing facilities where only liquefied petroleum gas(LP-Gas), liquefied natural gas (LNG), or compressed natural gas (CNG), or hydrogen is dispensed asmotor fuel.


NFPA Standard Council has moved all hydrogen requirements from NFPA52 to NFPA2, including those for Motor Fueling Dispensing and Repair Garages. The 2011 version of the NFPA2 code had specific information on Dispensing, but not for Repair Garages (reserved). The 2016 version of NFPA2 will have specific requirements for Repair Garages and will be published prior to NFPA30A. Therefore, in order to prevent conflicting requirements, hydrogen should be excluded from NFPA30A, as is LPG, LNG, and CNG.

Dispensing devices at the motor fueldispensing facility shall not be supplied by aboveground tanks located in the bulk plant. Storage tanks atmotor fuel dispensing facilities shall not be connected by piping to aboveground tanks located in the bulkplant.

4.2.3

Class I liquids shall not be stored or handled in a building that has a basement or pit into which ignitiblevapors can travel, unless the basement or pit is provided with ventilation that will prevent the accumulation

of vapors. The ventilation system shall be capable of providing at least 0.3 m3/min of exhaust per m2 of

floor area (1 cfm per ft2), but not less than 4 m3/min (150 ft3/min).

4.2.4

Where tanks are at an elevation that produces a gravity head on the dispensing device, the tank outlet shallbe equipped with a device, such as a normally closed solenoid valve, positioned adjacent to anddownstream from the valve specified in 22.13.1 of NFPA 30, Flammable and Combustible Liquids Code,that is installed and adjusted so that liquid cannot flow by gravity from the tank if the piping or hose failswhen the dispenser is not in use.

TITLE OF NEW CONTENT

Type your content here ...

4.3.2.8 Non-metallic tanks manufactured in compliance with and listed to UL SU 2258 shall be applicable inindoor and outdoor aboveground installation for Class II, Class IIIA and Class IIIB liquids. Installation,spacing and venting per the requirements of Section 4.3, Storage of Liquids


This addition to NFPA 30A would allow tanks manufactured to UL SU 2259 to be applied in combustible liquids storage installations where specified in the scope of SU 2258 supported by extensive and rigorous testing requirements of the standard.

From Subject 2258 Introduction: 1.1 These requirements cover nonmetallic or composite primary, secondary and diked type atmospheric tanks from 60 -660 gallons (227-2500L) intended primarily for the storage and supply of heating fuel for oil burning equipment, or alternately the storage of diesel fuels for compression ignition engines and motor oils (new and used) for automotive service stations, in above ground installations.

With the exception of standards UL 2080 (fire resistant tanks) and UL 2085 (protected tanks), UL SU 2258 would be the only other construction standard for combustible liquid storage with a pool fire test requirement.

(7) Dispenser Emergency Shutoff Valves – UL 842A Standard for Valves for Gasoline and Gasoline/EthanolBlends with Nominal Ethanol Concentrations up to 85 Percent (E0 - E85)


Section 6.2.3 currently requires dispensing equipment intended for use with alcohol-blended motor fuels to be listed or approved for the specific purpose. This was a good requirement when systems and components were not listed for this use. However a new generation of UL standards was developed to evaluate and list the components covered by this section for such use. This proposal provides the code user with references to the standards used to evaluate fuels with ethanol concentrations above E10.

(7) Dispenser Emergency Shutoff Valves – ANSI/UL 842, Standard for Valves for Flammable Fluids.


The body of the code stated that specific products were to be listed but there was no listed standard in the body of the code to support the requirement it was located in the Annex, which is unenforceable. This creates an enforcement nightmare because there was a disconnection between what the code demands and the means to attain it. This change resolves that issue.

7.3.1 Occupancy Classification.

The occupancy classification of a motor fuel dispensing facility that is located inside a building or structureshall be a special purpose industrial occupancy as defined in NFPA 101 , Life Safety Code determined inaccordance with the building code adopted for the jurisdiction .


Occupancy classifications are assigned by the Building code adopted in a jurisdiction. Special purpose industrial occupancy is an incorrect classification (see below) and this is a complicated situation best handled by requirements already clearly established in the building code. For most occupancies, adding a motor fuel dispensing facility inside an existing building would cause the MAQ to be exceeded if the storage is also inside, which would cause the occupancy to be a high hazard Group H occupancy and/or invoke additional Protection Level requirement (analogous to Group H) if NFPA 1 were to be enforced. Regardless, a special purpose industrial occupancy has lower egress requirements (not higher) that a standard industrial occupancy so this is not an appropriate occupancy classification.

Special-purpose industrial occupancies are intended for occupancies with uniquely low occupant load factors; not for occupancies that perform unique operations. Fuel dispensing facilities do not experience uniquely low occupant loads. In addition, egress may be inadequate if classified as a special purpose industrial occupancy. Refer to definition in NFPA 101 below as evidence that this classification is not applicable to fuel dispensing facilities:

3.3.190.8.3 Special-Purpose Industrial Occupancy. An industrial occupancy in which ordinary and low hazard industrial operations are conducted in buildings designed for, and suitable only for, particular types of operations, characterized by a relatively low density of employee population, with much of the area occupied by machinery or equipment.

In major repair garages, where CNG-fueled vehicles, hydrogen-fueled vehicles, LNG-fueled vehicles, orLP-Gas-fueled vehicles are repaired, all applicable requirements of NFPA 52, Vehicular Gaseous FuelSystems Code, NFPA2, Hydrogen Technologies Code, or NFPA 58, Liquefied Petroleum Gas Code,whichever is applicable, shall be met.


NFPA Standard Council has moved all hydrogen requirements from NFPA52 to NFPA2, including those for Motor Fueling Dispensing and Repair Garages. The 2011 version of the NFPA2 code had specific information on Dispensing, but not for Repair Garages (reserved). The 2016 version of NFPA2 will have specific requirements for Repair Garages and will be published prior to NFPA30A. Therefore, in order to prevent conflicting requirements, repair garages should reference NFPA2 and not NFPA52.

7.4.7 Gas Detection System.

Repair garages used for repair of vehicle engine fuel systems fueled by non-odorized gases, with theexception of hydrogen, such as hydrogen and non-odorized LNG/CNG, shall be provided with anapproved flammable gas detection system.

7.4.7.1 For repair garages used for the repair of hydrogen-fueled vehicles, the gas detection systemshall be in accordance with NFPA 2, Hydrogen Technologies Code

7.4.7.2 System Design.

The flammable gas detection system shall be calibrated to the types of fuels or gases used by vehicles tobe repaired. The gas detection system shall be designed to activate when the level of flammable gasexceeds 25 percent of the lower flammable limit (LFL). Gas detection shall also be provided in lubrication orchassis repair pits of repair garages used for repairing non-odorized LNG/CNG-fueled vehicles.

7.4.7.2 3 Operation.

Activation of the gas detection system shall result in all of the following:

(1) Initiation of distinct audible and visual alarm signals in the repair garage

(2) Deactivation of all heating systems located in the repair garage

(3) Activation of the mechanical ventilation system, when the system is interlocked with gas detection

7.4.7.3 4 Failure of the Gas Detection System.

Failure of the gas detection system shall result in the deactivation of the heating system and activation ofthe mechanical ventilation system and, where the ventilation system is interlocked with gas detection, shallcause a trouble signal to sound in an approved location.

7.4.7.4 5

The circuits of the detection system required by 7.4.7 shall be monitored for integrity in accordance withNFPA 72, National Fire Alarm and Signaling Code.


NFPA Standard Council has moved all hydrogen requirements from NFPA52 to NFPA2, including those for Motor Fueling Dispensing and Repair Garages. The 2011 version of the NFPA2 code had specific information on Dispensing, but not for Repair Garages (reserved). The 2016 version of NFPA2 will have specific requirements for Repair Garages and Gas Detection Systems. NFPA2 will be published prior to NFPA30A. In order to prevent conflicting requirements, the gas detection system requirements for hydrogen should reference NFPA2

8.2.1 *

In major repair garages where CNG vehicles are repaired or stored, the area within 455 mm (18 in.) of theceiling shall be designated a Class I, Division 2 hazardous (classified) location.

Exception: In major repair garages, where ventilation equal to not less than four air changes per hour isprovided, this requirement shall not apply.


The existing requirement as stated in 8.2.1 was based on the assumption as noted in Annex A8.2.1 that the creditable release on natural gas from the vehicle would be 150% of the largest on board storage cylinder. The volume released assumption was based on the noted premature failures of thermally activated PRDs (TPRD) experienced in the 1990's. Those TPRDS have gone through at least three generations on new designs and there has not been a documented failure (premature release) from TPRDs since 2002. This stems for the phase out of the older designs for the 1990's and the excellent performance record of the new TPRD designs. With thirteen years of no recorded failures (premature releases) of TPRDs mounted on hundreds of thousands of cylinders indicates that the release hazard covered by 8.2.1 no longer exists. A recent research paper (SAND2014-2342) from SANDIA National Laboratory and funded by the Clean Vehicle Education Foundation has determined that the expected creditable release for both CNG and LNG vehicles is of a much lower volume and dose not pose a hazard for a maintenance facility. The report includes gas dispersion modeling of the creditable releases showing the extent of the ignitable mixture. This modeling of the creditable mixtures indicate that the ignitable concentration is only within a narrow area no more than six feet from the point of release, also the limited volume of release does not allow for an increasing concentration in the ceiling area due to the dispersion of the gas.The full release as as noted in the 1990 assumption was also modeled for background information. The report also indicates that ventilation rates has little or no impact on the volume of ignitable mixture and the dispersion of the released gas.The report will be sent by separate cover as part of this proposal and an electronic copy is available to the TC as needed. The Annex A8.2.1 will need to be deleted and the TC should consider new annex material explaining the realities of creditable releases expected for contemporary facility designs, this information may be considered as Annex material for section 7.6.6 concerning locations of ignitable mixtures. NOTE: SANDIA has proposed a Phase 2 project to refine the assumptions for facility designs and CFD modeling starting in 2016 and would consider input from the NFPA 52 TC together define and understand the potential hazards.

Table 8.3.2 seems to conflict with the use of an AST in conjunction with a dispensing device when it comes to the definition of hazardous zones. Table 8.3.3(b) shows zones that are not near as large as those shown for ASTs in 8.3.2 with no clear definition to the differences. The only clue is that in 8.3.2 it refers to dikes around the tanks which would seem to indicate large storage tanks. This large zone around the tank can impact the hazardous classification required for the dispenser.

Section 8.3.2 refers only to class I liquids not gaseous fuels so the table exceeds its charging statement (8.3.2) by including gaseaous fuels. Also the requirements for hydrogen are included in NFPA 2.

30A_TIA_15-1.pdf TIA 15-1. Issue Date: March 14, 2014


This public input originates from Tentative Interim Amendment 15-1 (Log #1126) issued by the Standards Council on March 14, 2014 and per the NFPA Regs., needs to be reconsidered by the Technical Committee for the next edition of the Document.

TIA Submitter’s Substantiation: Chapter 12 of NFPA 30A provides certain provisions for alternative vehicle fuels, including compressed natural gas (CNG), liquefied natural gas (LNG), hydrogen H2, and liquefied petroleum gas (LPG). As part of these provisions, Chapter 12 mandates compliance with NFPA 52, Vehicular Gaseous Fuel Systems Code, NFPA 58, Liquefied Petroleum Gas Code, and NFPA 2, Hydrogen Technologies Code, except as modified by the chapter to accommodate dispensing of traditional liquid fuels (gasoline, diesel fuel).

At the First Draft stage for the 2015 edition of NFPA 30A, Public Input No. 21 proposed the above amendment in order to make the information specific to LNG consistent with NFPA 52. The resolution of this public input was to establish a Task Group to review Chapter 12 of NFPA 30A to confirm that existing requirements did not conflict with the other documents and to identify appropriate new requirements to address any provisions that were not consistent. The Task Group was asked to review several Public Inputs to Chapter 12, in addition to No. 21.

At the Second Draft stage, Second Revision No. 4 proposed amending Table 12.6.2 so that the Class I, Division 1 classification applied only to the interior of an LNG dispenser and the Class I, Division 2 classification applied outside the dispenser enclosure, out to a distance of 3 m (10 ft). During the transcription process, the text under the column heading “Class I, Division 1” that was supposed to have been deleted was not deleted. Consequently, the entry for LNG applies both Class I, Division 1 and Class I, Division 2 designations to the area within 1.5 m (5 ft)


90 of 100 10/26/2015 7:46 AM

of the dispenser enclosure.

Emergency Nature: If this error is not corrected, then Table 12.6.2 will apply conflicting area classification designations to the zone between the dispenser enclosure out to a distance of 1.5 m (5 ft). Electrical inspectors will be in a quandary as to which designation truly applies. Designers and installers will be faced with the same problem. Also, a potential conflict will exist between Table 12.6.2 and NFPA 52, as the latter classifies only the interior of the dispenser enclosure as Class I, Division 1.

Acceptance of this Tentative Interim Amendment will allow the 2015 edition of NFPA 30A to be published correctly.

This Tentative Interim Amendment is submitted in accordance with Section 5.3, Evaluation of Emergency Nature, Sub-Paragraph (a): NFPA standard contains an error or omission that was overlooked during a regular revision process.

Due to the lack of local enforcement on farms and remote areas, the requirement for capture of flammable liquids must be required to contain and prevent potential fires to humans, grass, equipment, buildings, and out structures that may be located adjacent to such tanks. Protection of the surrounding area and ground water from flammable liquids will increase overall safety.

Proposed TIA to NFPA 30A-2008:

1. Add a new definition of “alcohol blended motor fuel” to read:

“3.3.X* Alcohol Blended Motor Fuel. Motor fuel consisting of a blend of alcohol, such as ethanol, and gasoline with an alcohol concentration greater than 10 percent by volume, including those with nominally 85-percent ethanol / 15-percent unleaded gasoline (E85).”

2. Add a new Subsection 6.2.3 and accompanying annex item to read:

"6.2.3* Fuel-dDispensing systems devices and related dispensing equipment, including dispensers, hoses, nozzles, breakaway fittings, swivels, flexible connectors, dispenser emergency shutoff valves, and vapor recovery systems and pumps that are used for alcohol blended motor fuels shall be listed or approved for the specific purpose.”

“A.6.2.3 The majority of existing dispensers and related dispensing equipment are listed by UL for fuels up to E10 (i.e., 10% alcohol/90% gasoline blend). More recently, UL has begun listing dispensing devices for alcohol blended fuels up to E25 (i.e., 25% alcohol/75% gasoline blend) and E-85 (i.e., 85% alcohol/15% gasoline blend) (See UL SU87A, Outline for Power-Operated Dispensing Devices for Gasoline and Gasoline/Ethanol Blends with Nominal Concentrations up to 85 percent). While the existing dispensing devices and related dispensing equipment currently in service at motor fuel dispensing facilities are listed for use with fuels up to E-10, they are not listed for use with alcohol blended motor fuels (i.e., greater than 10% alcohol/90% gasoline blend). A significant consideration for approval of existing equipment for mid-level alcohol blended fuels such as E-15 (i.e., 15% alcohol/85% gasoline blend) is that mid-level alcohol blended fuels, if approved by USEPA, may likely become a replacement for current motor fuels either through state or federal mandates or supply chain restrictions. The availability of dispensing devices and related dispensing equipment listed for alcohol blended motor fuel is currently limited and listing for alcohol blended fuels will not be retroactive to existing dispensing devices and related dispensing equipment. In order to maintain the supply of motor fuel, this may require the sale of this fuel through existing dispensing devices and related dispensing equipment.

To address this issue, the authority having jurisdiction is provided with the ability to approve dispensing devices and related dispensing equipment currently listed for use with E-10 for mid-level alcohol blended motor fuels service (e.g. E-15). When approving a dispensing device or related dispensing equipment for use with alcohol blended motor fuels, the authority having jurisdiction may take into account other factors including, but not be limited to, actual field experience, more frequent inspection of the equipment, information from the manufacturer of the equipment, or evidence of compatibility and/or functionality by government agencies, trade associations, testing laboratories.” 3. Add a new entry to Table B.1, Typical Flammable and Combustible Liquids Found at Motor Fuel Dispensing Facilities, to read: :

“Alcohol Blended Motor Fuel / -40 °F – 55 °F / Class IB / varies / —“

Submitter’s Reason: The purpose of the Tentative Interim Amendment is to incorporate into the 2008 edition of NFPA 30A, Code for Motor Fuel Dispensing Facilities and Repair Garages, a

bbenedetti

Attachment No. A8

new provision, one that is being simultaneously proposed by the Technical Committee on Automotive and Marine Service Stations in the upcoming 2012 edition of NFPA 30A, that This will allow the application of the provision in jurisdictions that are currently and might be in the near future still subject to the 2008 edition of the Code.

Technical Validity: The proposal in question provides a means for the authority having jurisdiction to approve equipment for so called mid-level ethanol-blended fuel service (i.e., above 10 percent ethanol) dispensing equipment that is not currently listed for such use, as is required by the 2008 edition of NFPA 30A. Recognize that this equipment is currently listed for use with ethanol/gasoline blends containing up to 10 percent ethanol (E10).

It is left to the authority having jurisdiction to determine the factors to be considered in approving this equipment for use with higher (>10%) percentages of ethanol. The proposed annex provides guidance for the authority having jurisdiction. This guidance along with the leak detection requirements required under NFPA 30 and NFPA 30A and the USEPA underground storage tank regulations provide a level of assurance that potential issues associated with this equipment will be identified and resolved without incidentThese may include, but not be limited to, actual field experience, certification by the manufacturer of the equipment, additional equipment and controls, more frequent inspection of the equipment, or evidence of compatibility and/or functionality by government agencies, trade associations, testing laboratories, or any combination of these.

Emergency Nature: It is the submitter’s position that this TIA meets the criterion of Section 5.2(e) of the NFPA Regulations Governing Committee Projects for emergency nature. The U. S. Environmental Protection Agency has already approved the use of E85 in flex-fuel vehicles. It is anticipated that they will approve the use of mid-level ethanol blends (>10% but <85%) by mid-summer 2010. This leaves an even greater gap in the coverage of this equipment by NFPA 30A without this TIA. In addition, authorities having jurisdiction might be under legislative pressure to unilaterally approve equipment to store, meter, and dispense mid-level ethanol blends into vehicles based on the fact that the U. S. Environmental Protection Agency has approved such blends for use in most of the nation’s vehicles. The intent is to provide the means for the authority having jurisdiction to grant equivalency or an alternative, while still being protective of human health and the environment.

Tank-nically Speaking

Are Two Poppets Better Than One?

Crash valves installed at the base of dispensers are supposed to stop the flow of fuel from the

submersible pump when a vehicle hits the dispenser. Yet…

In New York State this past July (2014), a driver, suffering from a medical condition,

plowed into a dispenser at a high rate of speed. A substantial fire erupted immediately

Attachment No. A9

and was beginning to engulf the passenger compartment of the car when an off duty

policeman, who was filling up nearby, bravely pulled the unconscious driver to safety

(and then ran back to retrieve the ammunition in the trunk of his car before his vehicle

was engulfed in flames.) But for the courage of the bystander, the driver would have

been toast. (To view surveillance camera footage of this incident, go to:

https://www.youtube.com/watch?v=v0huLvek6I0&list=PLD185CA6C7ACA4E45&inde

x=51)

In Washington State (2012), a driver maneuvering at a gas station backed into a dispenser

and knocked it over. Flames erupted as the driver drove away. The fire continued to

burn for some time. (To view surveillance camera footage of this accident go to:

https://www.youtube.com/watch?v=gL360th3mFI&list=PLD185CA6C7ACA4E45&inde

x=40)

In Maine (2004), the inebriated driver of a pickup truck crashed into a dispenser, which

immediately erupted into flames. The driver backed up and drove away. A couple

fueling their car at a nearby dispenser ran for safety. An automatic fire suppression

system eventually put the fire out, but not before the flexible piping in the sump beneath

the dispenser had been substantially damaged by the heat. If an alert operator had not

activated the emergency stop switch to shut down the submersible pumps, the fire could

have been catastrophic. (To watch the video go to:

https://www.youtube.com/watch?v=zgTBtwoo1io&index=45&list=PLD185CA6C7ACA

4E45)

In each of these incidents, the single-poppet crash valves functioned as designed. Flow

from the submersible pump was stopped and no geysers of gasoline erupted from the dispenser

islands. But there were still serious fires that could have resulted in serious injuries or death.

How come?

Alas, the Single-Poppet Crash Valve

When a single-poppet crash valve shears, the valve mechanism in the bottom half of the crash

valve closes and stops the flow of fuel from the submersible pump. But the fuel already in the

dispenser can flow out into the environment because the top part of the crash valve contains no

valve mechanism.

How much fuel can be released? It depends on the dispenser design, but for dispensers

with three products on each side, there could be as many as six filters, six meters, six hoses, plus

tens of feet of tubing connecting all these components, potentially releasing several gallons of

gasoline. When the vapor from the spilled gasoline encounters broken electrical wires, sparks

from scraping metal, or hot components of the vehicle engine, the likelihood of a fire is high.

The result? Serious fires that cause significant damage and sometimes kill or severely injure

people.

Is There a Better Way?

A quarter century ago, at the request of oil companies seeking to limit the damage resulting from

vehicle/dispenser crashes, petroleum equipment manufacturers introduced the double-poppet

crash valve. The bottom half of the valve is identical to the single-poppet version of the crash

valve. The difference is in the upper half. In the double-poppet design, the upper portion of the

crash valve contains another valve mechanism that remains open as long as the crash valve

remains intact. When the crash valve activates in an accident, the upper poppet closes and the

gasoline in the dispenser components is contained.

Using double-poppet crash valves seems like a no-brainer in terms of safety. The

additional cost seems easily justifiable as well, because the cost of repairing extensive fire

damage from even one event will pay for the extra cost of a lot of double-poppet crash valves.

Despite the apparent advantages, fire codes and industry recommended practices (with one

exception) are silent on the advantages of double-poppet crash valves:

American Petroleum Institute Recommended Practice 1615, Installation of Petroleum

Storage Systems, states, “Double poppet or secondarily contained double poppet impact

(shear) valves should be considered for additional safety.” (API 1615 sixth edition, April

2011, p. 41).

PEI RP 100, Recommended Practices for Installation of Underground Liquid Storage

Systems, is silent on the matter. (PEI RP 100-11, p. 25).

The International Fire Code also does not indicate a preference for either single- or

double-poppet crash valves (IFC 2009, Section 2206.7.4).

NFPA 30A, Code for Motor Fuel Dispensing Facilities and Repair Garages, (the code

that has required the installation of crash valves since 1966) is also silent as to which type

of crash valve to use (NFPA 30A, 2012 edition, Section 6.3.9).

The NFPA Flammable and Combustible Liquids Code Handbook, which provides

background information and additional commentary concerning the code requirements, explains

that the NFPA Technical Committee does not recommend double-poppet crash valves because

some members of the Committee believe that these valves pose a hazard to emergency response

personnel. According to the Handbook, the concern is that if there is a fire surrounding the

dispenser, the fuel trapped inside the dispenser could “forcefully rupture,” endangering

emergency response personnel who might be working to control the fire (Flammable and

Combustible Liquids Code Handbook, 2012 Edition, p. 515). This has been the position of the

NFPA Technical Committee since at least the 1996 edition of the NFPA Handbook (Flammable

and Combustible Liquids Code Handbook, 1996 Edition, p. 404).

But is the scenario envisioned by the NFPA Technical Committee realistic? In other

words, do dispensers equipped with double-poppet crash valves commonly blow up when they

are hit and a fire results? Because a large number of double-poppet crash valves have been in

service for many years now, we should be able to answer this question. What has been the

experience of people who have used double-poppet crash valves as standard equipment for many

years?

To help answer this question, I sought the help of my colleague Ben Thomas of ????,

who has a vast network of contacts in the UST world. Here’s what we found.

Larry Gregory, who was responsible for Exxon’s gas stations on a global scale until a few

years ago, reports that he specified double-poppet valves immediately after they were

introduced. He is a firm believer in their ability to reduce fires when dispensers are hit

and reports that he has never heard of an incident where a dispenser equipped with a

double-poppet crash valve blew up.

An east coast petroleum marketer with well over a 1,000 stations has also equipped his

facilities with double-poppet crash valves for many years. He reports that on average he

sees a dispenser accident about once a week, but despite hundreds of dispenser impacts in

recent years, he has not had any fires that resulted from these incidents.

Another east coast petroleum marketer with several hundred gas stations uses double-

poppet crash valves exclusively and has thousands in service. These stations typically

experience one or two dispenser accidents a month, but in the past 18 years, there have

only been four fires. In one incident that resulted in a fire, the fire chief’s report

concluded that the fuel that ignited came from the vehicle and not the dispenser. This

company has never experienced a dispenser explosion.

John Albert, who administers Missouri’s tank program, reports that dispensers in

Missouri with non-metallic product piping must either have double-poppet crash valves

or fire extinguishers installed in a sump beneath the dispenser. The rules reflect John’s

experience that double-poppet crash valves greatly limit the potential for fires when

dispensers are hit. “We’ve had many dispensers get hit over the past 25 years, but very

few fires,” says John. He is aware of the differing points of view among fire officials but

has never had a dispenser explode because of a double-poppet crash valve. “My

experience is that the soft seals in the meter and filter are the first things to fail in a fire

scenario. This results in a slow release of product, but no explosion.”

OPW is a major manufacturer of both single- and double-poppet crash valves for use not

only in North America but also throughout the world. Glenn Eckart of OPW told us that

the OPW double-poppet shear valve has incorporated a pressure relief feature since it was

first introduced in the late 1980s. Since they were first manufactured in the late 1980s,

no one at OPW can recall ever receiving a report of a dispenser equipped with a double-

poppet crash valve exploding.

These anecdotal reports from a variety of knowledgeable people clearly point to the advantages

of double-poppet crash valves and provide no support for the NFPA position that these valves

pose a threat to emergency response personnel. We e-mailed Robert Benedetti, Principal

Flammable Liquids Engineer at NFPA, to ask whether they knew of any incidents where the

“forceful rupture” of a dispenser equipped with a double-poppet crash valve had actually

occurred. Mr. Benedetti replied,

This issue of single versus double poppet valves came up several editions of the code ago. At the time, the Technical Committee discussed this issue with respect to fire suppression activities. As I recall, the fire service representatives on the Technical Committee were leery of a fire beneath a dispenser whose components contained liquid that was “locked in.” This issue has never been brought up since. If experience shows otherwise, then all that needs to be done is for someone to submit a proposal to amend NFPA 30A to allow the double poppet design.

Bottom Line?

You guessed it. We believe that double-poppet crash valves have clear safety advantages over

the single-poppet versions and their use should be at least a recommended practice if not an

outright requirement. While some well-informed petroleum marketers are already using double-

poppet crash valves, many marketers who are not aware of the added safety provided by double-

poppet valves continue to specify the single-poppet versions. This substantially increases the

risk that fires will result when dispensers are hit and people will get seriously hurt. Our goal in

writing this article is to educate the UST community about this issue and to encourage UST

owners to seriously consider double-poppet shear valves as a means to limiting liability, limiting

damage, and ultimately, saving lives.

Oh, and we do plan to submit a comment to amend the next edition of NFPA 30A.

If you have a shear valve story you’d like to share showing how single- or double-poppet shear

valves did or did not save the day, we’d love to hear from you. Contact Ben Thomas at

Crash Valve Musts

While crash valves are the wallflowers of the UST world, waiting patiently for their turn to save

the day, they must not be ignored. Crash valves are critical pieces of UST safety equipment that

must be properly installed and maintained if they are to do their job. Here are some basics:

They must be rigidly anchored to the island and properly fastened to the dispenser

They must be installed at the proper height relative to the dispenser island

They should be tested for operation annually

Fittings tightness testers install in the test plug opening of the valves must NOT be left in

place when the tightness test is completed.

View this email in your browser

Calling all customers and friends: We are

conducting a survey about UST safety and need

your help!

As you may know, traditional, crash (or shear) valves installed at the base of fuel

dispensers have a single poppet that closes when the dispenser is subjected to a

significant impact like the picture above. This stops the flow of fuel from the

2

submersible pump, but still allows the fuel in the filters, meters, and piping inside

the dispenser cabinet to drain out. The fuel in the dispenser could amount to

several gallons and can cause a significant fire if it drains out and ignites.

Double-poppet crash valves were introduced about 25 years ago to contain the

fuel in the dispenser in hopes of greatly reducing the amount of fuel released in a

dispenser crash and so preventing major fires from occurring.

So do double-poppet crash valves prevent fires? Do you know of an incident

where:

1. A dispenser was hit;

2. There was/was not a fire as a result of the impact;

3. You know what type of crash valve (single or double poppet) was installed.

If so please contact us: we’d like to hear from you! Marcel Moreau and I are

working on an article for publication in LUSTline that documents the effectiveness

(or not) of double-poppet crash valves. If you have a story or general information

to share about this issue, email me at [email protected]; or call me at866-301-

Based on this inquiry, AUV needs to revise NFPA 30A, 6.7 to state the same as NEC Art. 514.11(A). From: Benedetti, Bob Sent: Wednesday, January 07, 2015 5:03 PM To: [email protected] Subject: RE: NFPA Technical Question Response [ ref:_00D5077Vx._50050YgqO3:ref ]

Good afternoon, Mr. Sparkman: I’m not sure if I can give a definitive answer here, since your questions relate to Article 514.11 of NFPA 70®, National Electrical Code®. I have no responsibilities with this Code; my responsibility is striuctly with NFPA 30A, Code for Motor Fuel Dispensing Facilities and Repair Garages. Nevertheless, I will provide my own informal non-binding opinions. NFPA 30a, in Section 6.7, requires that every fuel dispensing system have an electrical disconnect and that this disconnect must cut power to the dispenser, the fuel pump, and any related circuit elements. Beyond that, it does not specify. Article 514.11(A) of the NEC appears to me to be more specific. It states: “. . . to disconnect simultaneously from the source of supply, all conductors of the circuits, including the grounded conductor, if any”. The following is from the commentary on Article 514.11(A), as published in the National Electrical Code Handbook: “The intent is that no energized conductors are in the dispenser vicinity during maintenance or alteration. In the case of accidental reversal of the polarities of conductors at panelboards, the grounded conductor must be able to be switched to the open or “off” position.” I believe herein lies your answer, but you might want to submit this same inquiry to our Electrical Code Department via the NFPA 70 DocInfo page on our web site. Please understand that this response is a personal opinion and does not constitute a Formal Interpretation of the National Fire Protection Association, as noted below and as described in Section 6 of NFPA’s Regulations Governing Committee Projects. It is not to be relied upon to definitively determine compliance with any laws, ordinances, rules, or regulations. To determine legal compliance, you should refer to the appropriate authority having jurisdiction or seek legal advice. It is not intended, nor should it be relied upon, to provide professional consultation or services. To determine the adequacy or safety of any device or installation, you should consult with an appropriate professional. I hope this response is helpful.

Good afternoon, Mr. Sparkman: As we discussed during our earlier conversation, it is my opinion that the installation you describe is not an unattended motor fuel dispensing facility, as this term is defined by NFPA 30A. Such a facility is characterized by there being "no attendant or employee on duty". In contrast, the facility you describe involves fueling ONLY by employees of the facility. The facility is more correctly characterized as an attended fleet vehicle fuel dispensing facility.

From: Benedetti, Bob To: "Bausch, Eric L NWO" Cc: Gunkelman, Robert L NWO Subject: RE: NFPA 30 & 30A Truck Offload Separation from Tanks Date: Wednesday, March 09, 2011 4:56:00 PM Gentlemen: Thank you for sending me the photos and the summary of your dilemma. In thinking about this, I realize that the 25-foot and 15-foot separation distances in NFPA 30, Flammable and Combustible Liquids Code, originate with bulk plants and established a minimum separation between a storage tank and the loading rack that was supplied by that storage tank. In earlier editions of NFPA 30, there used to be a separate chapter on bulk plants and that is where this requirement originated. It had nothing to do with service stations or fleet refueling because, at that time, aboveground storage tanks were not allowed at either. So, we need to look at this in a different light. I tend to agree with you, as we discussed in Orlando, that laying 25 feet of hose to the loading box is a greater hazard than is the one purportedly being addressed, namely a fire originating at the delivery vehicle being a threat to the tank. It seems to me that the chances of having such a fire are aggravated by the length of the hose. In any event, this will be placed on the Agenda for the next meeting of the Technical Committee on Automotive and Marine Service Stations.

-----Original Message----- From: Gunkelman, Robert L NWO Sent: Thursday, March 03, 2011 8:19 PM To: [email protected] Cc: Bausch, Eric L NWO Subject: NFPA 30 & 30A Truck Offload Separation from Tanks Mr Benedetti, Thank you for your time at the NISTM conference on Monday. This is a follow e-mail on our discussion of the requirement to have fuel delivery trucks be separated from fuel tanks by 15/25 feet. My difficulty has been to located 2085 tanks for land vehicle fueling on military bases (fleet facilities) and safely maintaining the truck to tank separation distance. Some sites have resulted in parking the delivery trucks on a concrete hardstand 25 ft from a tank with the fillbox attached to the tank structure. This results in the delivery trucks having to lay the offload hoses across the pavement and (hopefully) blocking traffic next to the tank and tank mounted dispenser. My concern is that this creates much more of a safety hazard than having the truck pull-up next to the fillbox to offload fuel. I have been able to safely located the truck away from the tank on other projects, but this has been costly as general spill containment/concrete pavement is required at both the dispensing areas (next to the tank) and truck offload area. I request that this issue be looked at for, at least, fleet facilities. Thank you, Robert L Gunkelman, PE Civil Engineer - POL-DX Corps of Engineers - Omaha District 402-995-2201 (W) 402-315-0718 (M)

I honestly believe the industry should pursue this and related items like mandatory electrical grounding of any/all risers or vents that have access to tank inventories that are flammable or combustible. This latter subject is now far more of a concern in my mind since secondary containment, exterior coatings, and the use of dielectric materials have removed much UST system hardware from traditional grounding paths. Unfortunately, with most majors now spinning off their direct market assets, this will probably prove to be much more difficult. Glen Marshall -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Tuesday, November 16, 2010 5:08 PM To: Wayne Geyer Subject: Fwd: RE: Lightning Ignites UST Wayne - I really appreciate your continued efforts on this. VERY unusual explanation as it initially seems at odds with physics. The "earth ground" may have been the fill ring set in concrete in physical contact with the backfill soil. The "ground" structure may also have included a tank riser which may have been an uncontained/unprotected steel pipe. If the ground/soil were wet, that's another factor supporting grounding. The fill tube was inside a dielectric containment (tank), so it had no access to earth ground other than the above structure. The tank ullage should still have been too rich to support ignition. However, this lack of adequate oxygen would change drastically as you travel up the fill towards the connection point at grade. The opposite is true for the fuel vapors which will lean out as we come up towards grade since the vapors are heavier than air. Nevertheless, somewhere in that scenario, the electrical energy apparently arced in an area where the fuel vapors were still rich enough and finally had access to sufficient oxygen to light off. As for the woman smoking a cigarette in her truck while parked over the tank field, I suspect she was a non-factor that simply happened to be in the wrong place at the wrong time. Probably the last time she'll ever be in that position again due simply to fear and superstition. I think the same results would have occurred regardless of which fuel grade the lightning chose to strike. Gasoline is more volatile (easier to ignite) and diesel contains more btu's of energy than gasoline. Either way, no tank, regardless of construction material or numbers of walls, is going to successfully resist the explosive pressures applied. I have long been a proponent of electrically grounding any/all tank risers that have access to stored fuel/fuel vapors in the tank. This is aimed at reducing static ignition arcing during connection/disconnetion of fuel delivery hoses (hook up ground first and last in said process). However, I doubt grounding would have had any significant affect whatsoever on the possible scenario discussed above. It may also be that at the massively elevated energy and temperature levels of a lightning strike, ordinary electrical theory just doesn't work as we expect. Finally, no, I've never heard of or dealt with any lightning strikes on UST systems. But then, engineering is not the exact science that most people assume it to be. There's still a tremendous amount of information and physical phenomena that we just do not understand. Again, thanks for your efforts to chase this down.

From: Robert RenkesTo: Benedetti, BobSubject: Questions for 30A CommitteeDate: Monday, August 19, 2013 10:24:55 AM

Bob—As you know, I had intended to attend the meeting on Thursday but circumstances(granddaughter care) prevent me from making the trip. Guy has to do what he has to do. If I was there, I would have discussed the coordination of 30A and 52 with the committee. Indrafting PEI’s new recommended practice on CNG dispensing systems, the committee has run intoseveral problems concerning E-stops that I’d hope the 30A committee could resolve. Here is how Iunderstand the codes and the queries from our CNG committee:

· Specifically, 30A is applicable to CNG facilities only when booth gasoline/diesel and CNG aredispensed from the same motor fuel dispensing facility (1.1.2). I assume that means theentire property on which the station is located. I think I’m correct on this.

· If a CNG dispenser is on the same island (either under the same canopy or an adjacentcanopy) as a gasoline dispenser, then how far is the E-Stop to be located from thedispenser? 30A says not less than 20 feet or more than 100 feet from the fuel dispensingdevices that they serve (6.7). 52 says within 10 feet and also greater than 25 feet from thedispensing area 7.11.5). Which code are they under?

· Same scenario as above. Should the CNG E-Stop cut off power to the liquid dispensers aswell? And should the liquid E-Stop cut off power to the CNG dispenser? Does that answerchange if the dispensing is done a distance away from each other—i.e., the other side of thebuilding or so many feet away in a separate, stand-alone island? In that case the station canuse the two different distances without much problem—but what is required to be shut off—in that case, I think 30A controls but I am not sure.

Do you have the answers and/or do you mind posing the questions to the committee? Thanks. Bob Bob RenkesExecutive Vice President/General CounselPEIP. O. Box 2380, Tulsa, OK 74101918-494-9696 Follow me on Twitter!

NFPA 30A Gap Analysis

Action Items or Questions to Resolve: 1.1.3 Scope – The 30A Code is not applicable to dispensing facilities for only … LPG, LNG, CNG …, so need to: a) clarify if “only” applies to Gas/Diesel vs others noted, or each alternate fuel, such as a combined LPG & CNG facility. If dual Code(s) apply, does 30A take the lead? b) add GH2 to list and NFPA 2 to 2.2 list of referenced publications? 2.3.3 UL Publications – Add UL87A, UL87B, UL87C, UL142, UL142A, UL2039, UL2583, and others to list if needed to support the Flex-Station and establish applicable Safety requirements for the system components? Also needed for current fueling stations? 3.3 General Definitions – Add a new definition to describe the Flex-Station product and concept of factory built modular units for different fuels with elevated tanks that are installed and serviced in a non-traditional way? 4.3.2 Aboveground Tanks – Add new subsection to ref applicable tank Standards for LPG, CNG & GH2, the different pressures they operate at, allow “elevated” use and clarify: a) if 4.3.2.3 individual (12k gal) and aggregate (48k gal) and 4.3.2.5 for “fleet” values, applies to only traditional liquid fuels (gas, kero, diesel) or also alternate gaseous fuels (LPG, CNG, GH2), and b) if the corresponding minimum separation distances of Table 4.3.2.4 for UL2085 tanks includes “elevated” use, and if “other” tanks also includes alternate gaseous fuels (LPG, CNG, GH2) 5.2.7 Piping Components – Do requirements for “low melt point” materials include valve seats/gaskets, and if so, must they be 2 hr fire rated? 5.3.2 Flex Connectors – Ref UL2039 as the requirements for all “Listed” flexible connectors. See separate UL agenda item. 5.6.3 Tank Vents – Does the min 5’ vent pipe above “the height projection of the canopy” apply to the perimeter, components or accessories? 6.2.3 & 6.2.3 Fuel Dispensers – Ref UL87A & UL87B as requirements for all Listed fuel dispensing systems (gas, kero, diesel). See separate UL agenda item. 6.3.4 Dispenser Island – Propose revision to include metal (vs concrete) as a suitable island support for dispensers. 6.7.2 Emergency Disconnects – Can the 2nd electrical disconnect be located on a stand-alone post or adjacent island? 7.3.5 & 9.2.5 Fire Protection – Would combination of fire resistance, fire detection and portable/fixed extinguishers meet the highest level of AHJ requirements? 7.6 Heating Appliances – Would Flex-Station options (generator, compressor, PV collectors, batteries) be considered “heat producing appliances”, and would 7.6 apply to the canopy top since not in a building (implied)? 9.2.1 & 9.2.2 Delivery & Control – Are alternate fuels intended to meet NFPA 385 bulk delivery and inventory control requirements, or different ones? 9.2.5.4 & 9.5.3 Warning Placards – Are other items specific to the Flex-Station needed on warning placards? Ch 8 & 12 - See separate Classified Areas Assessment for Flex Station Modules with Different Fuels for additional gap analysis and questions specific to these chapters.

CLASSIFIED AREAS ASSESSMENT for FLEX-STATION MODULES with DIFFERENT FUELS

NFPA 30A references NEC 70 for electrical wiring & equipment, and uses the Article 500 System to classify location ratings (Class, Division, Group): Class I = Electrical equipment use in hazardous areas where flammable or explosive vapors may exist; Div 1 = Hazard is present in normal conditions Div 2 = Hazard is present in abnormal conditions Group A = N/A (acetylene) Group B = Processed gasses >=30% H2 (includes GH2) Group C = MESG >0.45 to <=0.75 mm and MIC Ratio >0.4 to <=0.80 mm Group D = MESG >0.75 mm and MIC Ratio >0.80 (includes Gasoline, LPG & CNG) Please ref the (AAIZ) Guide for additional information on Hazardous Locations. With respect to NFPA 30A identification of classified locations & installation requirements for electrical wiring & equipment, there are general references to NFPA 58 (LPG), NFPA 52 (CNG), NFPA 2 (GH2) and NFPA 70, (all fuel types). However specific requirements in Ch 8 for traditional liquid fuels (Class I gasoline & gasoline blends) and Ch 12 for alterative gaseous fuels (LPG, CNG, but not specifically GH2) are applicable if dispensed in a mixed fueling facility. The following summary of these requirements applies to the Flex Station modular design: Par 8.3.1 & 8.3.2 (for traditional liquid fuels) – Class I (Gasoline) and use Table 8.3.2 & Fig 8.3.2 to determine if a Div 1 or 2 area. Par 12.6.2 (for alternate gaseous fuels) – Class I (LPG & CNG) and use Table 12.6.2 (revised by TIA) to determine if a Div 1 or Div 2 area. Note 1 - Although GH2 is identified as a Class I, Div 1 or Div 2, Group B fuel, it is not specifically covered by NFPA 30A Ch 12. NFPA 2 Ch 10 has better information on GH2 fueling stations. Note 2 - Class II (Diesel) fuels are unclassified locations, except if within a “hazardous” location of adjacent Class I fuel. However, UL Listed dispensers assume, and are rated for installation next to gasoline dispensers. Potential Problems we see with the Flex Station modular design to locate fuel tanks and electrical equipment in the canopy, which if connected to adjacent canopies with different fuels, as intended. This would not comply with minimum separation distances per 12.3.4 – Where, the minimum 20’ separation distance applies between tanks and/or dispensers of different fuels. However, it may be possible to apply exceptions for sealed enclosures per 8.3.3 or exceptions in Table 8.3.2 “where effectively cut off by walls or partitions”, to reduce either: a) Classified locations (hazardous to unclassified), or b) Division ratings (Div 1 to Div 2), or c) Distances related to the above ratings. Therefore, the above questions, and fundamental question of - were the “aboveground” requirements developed only for “at grade” tanks, or can they also apply to “elevated” tanks – should be submitted to the NFPA 30A TC for a response.

Optional Electrical Accessories or Systems either a) in adjacent canopy boxes (such as power panels, generators, batteries & wiring), b) on the canopy/cover (such as PV panels & lightning protection) or under the canopy (such as lights & sensors) must be rated for the hazardous location. Note if CNG compressor units are used, they will be separate from the Flex Station. (?) Consideration must be given to different gas/vapor properties that may collect within/under or escape from various dikes or enclosures. ($) It is also unknown at this time if barriers intended to eliminate or reduce hazardous locations are applicable to the canopy box design.

(*) = Measured in any direction from grade.

(Not in 12.4) NFPA 2 T10.3.1.16.1 – If compression/ancillary equipment is in the canopy, unsure if the Div 2 <=15’ distance is mitigated by canopy or other barriers. Also unsure if the tank relief device Div 1 @ <=5’ and Div 2 @ <=15’ within 15 deg of discharge is mitigated by canopy or other barriers. NFPA 2 T10.3.2.3.1.3 - See separation distances from different GH2 components & operations when considering the site location. ($) It may be possible to apply exceptions for sealed enclosures per 8.3.3 or exceptions in Table 8.3.2 “where effectively cut off by walls or partitions“, to reduce either: a) Classified locations (hazardous to unclassified), or b) Division ratings (Div 1 to Div 2), or c) Distances related to the above ratings. The tank/pipe pressure relief device & design should consider a resulting fire, where the outlet position must point upwards, or otherwise in directions that will prevent a) flame contact on adjacent tanks, equipment, buildings and properties, & b) gas collection or extended hazard zones for different heavier vs lighter than air types.
