This list represents the membership at the time the Committee was balloted on the text of this edition. Since that time changes in the membership may have occurred.

The Supplementary P, eport of the Committee on Recreational Vehicles is presented for adoption in 2 parts.

Part I of this Supplementary Report was prepared by the Technical Committee on Recreational Vehicles, and proposes for adoption a Supplementary Report which documents its action on the public comments received on its Report on NFPA 501C-1990, Standard on Recreational Vehicles, published in the Technical Committee Reports for the 1992 Fall Meeting.

Part I of this Supplementary Report has been submitted to letter ballot of the Technical Committee on Recreational Vehicles which consists of 18 voting members; of whom at least 2 /3 voted affirmatively on each of the proposed actions on comments, as calculated in accordance with Section 12-4 of Regulations Governing Committee Projects. One ballot ~as not returned (Mr. Rivers).

Committee members who voted negatively or abstained on the Committee Action on certain comments, a~ld their reasons for so voting, follows: (Vote is negative unless otherwise noted.)

Comment 501 C-8 (2-2 7.:.) Exception) (Log #17)

Mr. Bond: This change will allow the LP-Ga.s containers to be located where access to the containers main shut-off valve would be hindered by the vehicle's frame or other parts. I fa leak should develop between the containers main shut-off valve and a remote electronic shut-off val~ e, a person would be put in a hazardous position crawling under the vehicle to attempt to close off the containers main shut-off valve. Although the commi,ttee accepted the change, they asked for input

from NFPA 58 panel and I feel that we need that intmt before this is allowed.

Mr. Crawford: The present language of 2-2.7.2 should be retained unchanged. The container should be located so the manual strut-off valve is within 18 in. of the outside wall of the vehicle. This will provide accessibility for positive manual shut-off waive could still be provided, but the manual valve must be easily accessible as a back-up in case tile electric valve fails to close in an emergency situation.

Comment 501C-11 (2~1.2(0) (Log #9)

Mr. Crawford: The comnfittee action was to reject the o:munent which opposes the proposed revision to 2-4.2(0. The rt-vision

~ roposed by the coumfittee allows flexible nonmetallic tubing or ose to be used as RV g~s piping material if the hose is listed and

used in conjunction with listed fittings. The comnfittee has deleled the phrase requiring that the hose be listed fi)r the intended use.

The only standarcks I am aware of under which flexible nonmetallic gas hose can be listed for use with LP gas art: UL 5B9 and LIL 21. [ IL 569 applies only to a complete flexible hose connector assembly as required by the present language of 2-4.2(t). UL 21 ap[,lies to the hose without fittings, but this standard specifically states in paragraph 1.3-C that it does not apply to "hose intended for use in automotive applications or hose intended for use in e,~nliued areas." In my opinion, a recreational vehicle is an automotive application and certainly it is a confined area. ttence it appears that [ rL 51iLA is the only existing stancLard covering flexible nonmetallic gas h,~se f~w use ill RV applications.

Based on the above analysis, the present language ot 2-4.2(t5 should be retained.

Comment 501 (2-16 (3-2.5) (Log #11)

Mr. Crawford abstained with the following commeut: "The requirements for exit opening size shouM be consistent with

corresponding coverage in ANSI A119.5 for park trailers."

Comment 501 (5-17 (3-4.1) (I ,og #.t)

Mr. Bloom: It is agreed that a minimum 5 B:C extinguisher can sulfice in non-

motorized equipment, such as for a tent trailer, pull trailer, camper, and fifth wheel vehicles. However, equipment with gas,l ine ,,r diesel engines should be considered in a different category, ~ the fuel load and fire potential are vastly different. For those recreational vehicles, required. These units carry a large amounl . f gasoline, are equipped with transmissions subject to boil-over, and use rubber fuel lines that are subject to deterioration.

Comment 501G-19 (34.1) (Log # 15)

Mr. Bloom: There is no ~greater satety risk associated with the size o fa III B:C

fire extinguisher than a 5 B:C. Many 10 B:C extinguishers are the same diameter ,as the 5 B:C and are sligbtly longer, which allows for mount ing the larger extinguisher in the same b~cation as the smaller.

As far as I have been able to determine from available information from fire data, state and municipal fire marshal's officers, and insurance claims officers, there are no documented cases oflire extinguishers becoming a deadly projectile as the resuh of an accident. Mounting brackets are designed to prevent this scenario.

However, there are numerous documented cases of persons with a small fire in the engine comparunent or transmission of a motorhome who have stated that the 5 B:C extinguisher did not have enough agent, and could have had the fire out if only the extinguisher was the next larger model, h~stead of a small fire whicb could have been extinguished, the vehicle and contents became a total loss.

There are also documented cases of persons, including two cases that I have been involved with, involving paraplegics, who bare been trapped inside burning units, whicb could have been extinguished in its initial fire stage with a slightly larger extinguisher.

Comment 501 G-g0 (34.1) (Log # 14)

Mr. Bloom: The justification for a larger (10 B:C) fire extinguisher is well

documented in both fire department and insurance loss records. The committee must realize that a motorhome witl~ its engine, generator, and available flammable fuelpresents a ~vtstly different fire potential than a travel trailer which does not contain gasoline. Tile cost difference to the manufacturer is almost negligible, and presents a much greater degree of fire safety potential to the consunler.

In closing, this commit tee is charged with FIRE SAFETY. As an ex- firefighter and presently a fire cause investigator who sees recreational vehicles in a non-showroom condi t ion on n u m e r o u s occasions each year, I canno t stress too strongly the impor tance of having a m i n i m u m 10 B:C ext inguisher r equ i r emen t for fueled equipment . I would hate to have to have our commit tee reconsider this request in a subsequen t mee t ing as the result of a fire fatality or injury tha t could h a v e b e e n avoided by requir ing an ext inguisher only the next size larger, and at minimal cost to the manufacturer .

Part II of this Supplementary Report was prepared by tile Technical Commit tee on Recreational Vehicles, and proposes for adoption a Supplementary Report which documen t s its action on the public comment s r ece ivedon its Report on NFPA 501D-1990, Standard on Recreational Vehicle Parks and Campgrounds , publ ished in the Technical Commit tee Reports for the 1992 Fall Meeting.

Part II of this Supplementary Report has been submit ted to letter ballot of the Technical Commit tee on Recreational Vehicles which consists of 18 vot ing members ; of whom 17 voted affirmatively, and 1 ballot was not re tu rned (Mr. Rivers.)

PART I

(Log # 16) 501C-1 - (1-2.2 (New)): Accept SUBMITTER: Kent Perkins, RecreationalVehicle Industry Assoc. COMMENT ON PROPOSAL NO: 501C-2 RECOMMENDATION: Delete the first portion of the first sentence "The provisions of this document are" and move the remainder of the sentence to the end of the sentence in section 1-2.1 Applicability. Also add the rest of the recommendat ion to existing 1-2.1. SUBSTANTIATION: The creation of a whole new paragraph is not warranted since this information deals wifla applicability rather than retroactivity. COMMITTEE ACTION: Accept.

(Log # 10) 501C- 2- (1-2.2): Accept SUBMITTER: Robert E. Wozniak, Fleetwood Enterprises, Inc. COMMENT ON PROPOSAL NO: 501C-2 RECOMMENDATION: Delete the words "and property" in the first sentence. SUBSTANTIATION: NFPA 501C is a safety standard that deals primarily with firesafety criteria for recreational vehicles. Product durability has not and should not be a dominant factor in this Recreational Vehicle Fire and Life Safety standard. Therefore, the words "and property" should be deleted. COMMITTEE ACTION: Accept.

(Log # 23) 501G- 3 - (1-3): Accept in Principle SUBMITTER: Bruce A. Hopkins, Recreational Vehicle Industry Assoc. COMMENT ON PROPOSAL NO: 501C-5 RECOMMENDATION: 1. Reject the proposed change to RV by deleting the term park trailer from this definition.

2. Revise TT to read as follows: "Travel Trailer: Avehicular unit, mounted on wheels, designed to

provide temporary living quarters for recreational, camping, or travel use, and designed for daily transits by its owner or operator, of such size of weight as not to require special highway movement ~ermits when towed by a motorized vehicle (~ .d of/~ . . . . k, ~ilcl . . . . , c s s aaaa ~,~ sq , , / . (See Recreauonal Veh cle. )

3. Delete the existing GTA definition. SUBSTANTIATION: The existing federal law defines manufactured home as "a structure, transportable in one or more sections, which in the traveling mode, is 8 body ft or more in width or 40 body ft or more in length or when erected onsite is 320 or more sq f t . . ." . This definition encompasses park trailers and large travel trailers.

However, under this law, HUD only regulates manufactured homes that are defined as structures that exceed 400 sq ft when measured in accordance with HUD's Manufactured Housing Interpretive Bulletin A-1-88. Anything less than 400 sq ft is classified by HUD as an RV and is not regulated as a manufactured home.

The definitions relating to recreation vehicles, travel trailers, and park trailers are an administrative issue, not one of safety. The requirements of safety that are detailed within the text of the standards that apply to RV products, however they are defined.

Our intent is to eliminate the on-going confusion by redefining travel trailer and park trailer to reflect the primary functions of these products. The functicnal distinction are as follows:

Travel Trailer - Frequently moved and not designed for destination or seasonal camping.

Park Trailer - Seldom moved and designed primarily for destination or seasonal camping, not designed to be a permanent dwelling.

NOTE: "Supporting material is available for review at NFPA Headquarters."

COMMITTEE ACTION: Accept in Principle. Revise the definitions for Recreational Vehicle and Gross Trailer

Area, add new definitions for Fifth Wheel Trailer, and Park Trailer, and add new Appendix D as follows:

Fifth Wheel Trailer. A vehicular unit, mounted on wheel, designed to provide temporary [Mng quarters for recreational, camping, or travel use, of such size or weight as not to require special highway movement permit(s), of gross trailer area not to exceed 400 sq t , and designed to be towed by a motorized vehicle that contains a towing mechanism that is mounted above or forward of the tow vehicle's rear axle. (See "Recreational Vehicle.")

Gross Trailer Area. The total plan area measured to tile maximum horizontal projections of exterior walls in the set-up mode. (See Appendix D.)

Park Trailer. See ANSI A119.5, Standard for Park Trailers. Recreational Vehicle. Avehicular type unit primarily designed as

temporary living quarters for recreational, camping, travel or seasonal use, that either has its own motive power, or is mounted on, or towed by another vehicle. The basic entities are: camping trailer, fifth wheel trailer, motor home, park trailer, travel trailer and truck camper (see individual definitions.)

Travel Trailer. (No change.) Appendix D In calculating the square footage, measurements shall

be taken on the exterior. Square footage includes all siding, corner trims, moldings, storage spaces, areas enclosed by windows but not the roof overhangs (Ref. HUD Interpretive Bulletin A-1-88.)

Expandable room sections, regardless of height shall be included. Storage lofts contained within the basic unit shall have ceiling heights less than 5 ft and would not constitute additional square footage. COMMITrEE STATEMENT: The committee voted unanimously to accept the definitions relating to RV's, 5th wheels, a ndpa rk trailers as developed and approved by the ANS A119 on RV andParks at their May 5, 1992 meeting in Laughlin, NV.

(Log # 8) 501C- 4 - (1-3): Accept in Principle SUBMITTEI~ Joseph C. Anicich, Skyline Corp. COMMENT ON PROPOSAL NO: 501C-5 RECOMMENDATION: Revise text as follows:

Recreational Vehicle: Avehicle-type unit 400 sq ft or less primarily designed as temporary living quarters for recreational, camping, or travel use, which either has its own motive power or is m o u n t e d o n or t ~ l - d r a w r l by another vehicle. Tile basic entities are: travel trailer, Dark trailer, camping trailer, truck camper, and motor home.

Travel'Trailer: A vehicular unit mounted on wheels, designed to provide temporary living quarters for recreational, camping, or travel use, of such size or weight as not to require special highway movement permits when towed by a motorized vehicle, and ,,f ~,i ,,~.~, ~i ailcl al ca less d,an 320 sq f~ primarily designed for daily transit by its owner or ot)erator. (See "Recreational Vehicle")

Park Trailer:" (See ANSI A119.5 Standard) "Park Trailer: A vehicular unit that meets tile following criteria: (a) Build on a single chassis mounted on wheels. (b) Primarily designed as a temporary living quarters for seasonal

or destination camping which may be connected to utilities necessary for operation of installed fixtures and appliances. (See "Recreational Vehicles")." SUBSTANTIATION: HUD bas an exemption from the National Manufactured Housing Construction and Safety Act of 1974 for Recreational Vehides that have an overall size limitation, in the set- up mode, of 400 sq ft or less. Therefore, all recreational vehicles should have a maximum size limitation, in the set-up mode, of 400 sq ft. Also, if park trailers are to be recognized as recreational vehicles they should be included into the "Recreational Vehicle" definition. COMMITrEE ACTION: Accept in Principle. COMMI'IWEE STATEMENT: See Committee Statement under 501Cr3 (Log #23).

(Log # 5) 501C- 5 - (1-3): Accept in Principle SUBMITTER~ James L. Bond, State of Arizona, Office of Manufac- tured Housing COMMENT ON PROPOSAL NO: 501C-5 RECOMMENDATION: Revise Travel Trailer to read as follows and add new definition of Fifth Wheel Trailer.

Travel Trailer. A vehicular unit, mounted on wheels, designed to provide temporary living quarters for recreational, camping, or travel use, of such size or weight as not to require special highway movement permits of ~ross trailer area less than 320 so ft and designed to be when towed by a motorized vehicle containing a towing mechanism that is mounted behind the tow vehicle's bumper (or equal). , . d , , i~ . . . . h~ilci hi ca 1c53 tl~i~l 320 sq f~ (See "Recre- ational Vehicle.")

(See "Recreational Vehicle"). SUBSTANTIATION: As stated in the proposal it is necessary to have further clarification between travel trailers and park trailers. However, in working to make this clarification it was recognized that fifth wheel trailers should not be classified as park trailers and size

limitations between Travel Trailers and Fifth Wheel Trailers needed to be different. The suggested changes will better address the proposal submit ter ' s concerns while providing addit ional guidance and direction to those involved with standards. COMMITTEE ACTION: Accept in Principle. COMMITTEE STATEMENT: See Commit tee Sta tement unde r 501 C-3 (Log #23).

(Log # 6) 501C- 6 - (1-3 and Appendix E (New)): Accept in Principle SUBMITTER: James L. Bond, State of Arizona, Office of Manufac- tured Hous ing COMMENT ON PROPOSAL NO: 501C-5 RECOMMENDATION: Change Gross Trailer Area and Recreation Vehicle definit ions as shown mid add Appendix E.

(Log # 24) 501C- 7 - (1-3 and Appendix E (New)): Accept in Principle. SUBMITTER: Gary Wight, Nat'l C a m p g r o u n d Owners Assn. COMMENT ON PROPOSAL NO: 501 C-5 RECOMMENDATION: Revise text as follows:

Recreational Vehicle: A vehicular-type uni t primarily des igned to provide travel and dest inat ion RVing, that e i ther has its own motive power or is m o u n t e d on or towed by ano the r vehicle and is of such size and weight as no t to require special highway m o v e m e n t permits. The basic uni ts are travel trailer, 5th wheel trailer, park trailer, camping trailer, truck camper, and motor home. (See Appendix E).

Travel Trailer. A recreational vehicle, m o u n t e d on wheels, designed to provide travel and dest inat ion RVinm of a gross trailer area less than 320 sq ft and des igned to be when ' towed by a motor ized vehicle conta in ing a towing mechan i sm that is m o u n t e d beh ind the towvehicle ' s b u m p e r (or eoualL

Fifth Wheel Trailer. A recreational vehicle des igned to provide travel and destination RVinm m o u n t e d on wheels, des igned to be towed by motor ized veh ic lecon ta in ing a towing mecha~nism tha~ is m o u n t e d vertically above or forward of the tow vehicle 's rear axle(s).

Park Trailer. A recreation vehicle des igned to provide destination RVinm built on a single chassis, mountecl on wheels and which may reaui re snecial hiffhwav m o v e m e n t oermits.

Camoin'~ Trailer~ A recreational vehicle designed to provide travel and dest ination RVinm that is m o u n t e d on wheels and 'cons t ruc ted v with collapsible oartial side walls tha t fold for towin~ bv ano the r vehicle an'd unfold for use.

Truck Camoer. A recreat ion vehicle designed to orovide travel and dest inat ion lOVing and consisting of a roof,f loor, and sides des igned to be loaded onto and un loaded f rom the bed o f • pickup truck.

Motor Home. A recreational vehicle des igned to orovide travel and dest inat ion RVing built on or permanendy~attache~t to a self- propelled motor vehicle chassis or on a chassis cab or van that is an integral part of the comple ted vehicle.

Appendix E RVs are not in tended to exceed 400 so ft in the t ransoortat ion or

set-uo mode. To de te rmine total size use HUD's Inte(nretive Bulletin A-1-88, The applicable port ions are t ) rovided]n the blocked text below.

By regulation, the Dena r tmen t of Hous ing and Urban Develop- men t h~as exemoted recreational vehicles fr'om the reuu i rements for manufac tu red laomes in the Standards Act of 1974 ("Act"). Recreational vehicles are def ined in Ùart as "a vehicle which i s . . . 400 square feet or less when measured at the largest horizontal nroiections. , " 24 C.F.R. Section 3282.8(g)(~). It has corne to the i)et~artment 's at tent ion that confusion exists in both the manufactured housin~ and recreational vehicle industries. Snecificallv, quest ions havre arisen concern in~ the correct metho~t of measure- men t of homes for purposes of d~eterminin~ the applicabilitv of the recreational vehicle e x e m o d o n at 24 C.F.R~'Section 3282(~ . In Darticular. there seems to 'be confusion about what is m e a n t bv tbe largest horizontal projection and what parts of the h o m e are included in calculat i@ the 400 square feet.

Accordingly, HUD interorets section 3282(g) as follows: In calcula'tiiag the square footage of a home. measu remen t s shall be

taken on the exterior of the home. The square footage includes all siding, corner trim. and molding, storage space, and area enclosed bv windows but no t the roof overhand.

Expandable room sections, regardless of he igh t would be included. Storage lofts contained within the basic 400 s~uare feet having ceilin~ heights less tharl 5 feet would not constitute additional" s c l u a r e f o o t a g e .

SUBSTANTrATION: Definitions of park trailer and 5th wheel trailer are no t included in the 1990 edition of this standard. Revised definitions of recreational vehicle 's basic units were made to simplify language and reflect the above definit ion of recreational vehicle, and to clarify the confusion between travel trailer and park trailer. Listing all the types of recreational vehicle units unde r the definition of recreational vehicle will fur ther help el iminate confusion.

The word "RVing" is being used t h r o u g h o u t the industry to better define the actual use of recreational vehicles ra ther than the word "camping" which is more indicative of tent ing and dry camping ra ther than the use of an RV in an RV resort park.

RVing: A life style. Traveling a n d / o r living independent ly where one chooses. Camping for the en joyment of the outdoors. A way of life. To use a recreational vehicle for recreation. To be associated with the fraternity of other like RVers. To use a recreational vehicle for its in tended use. To exercise ones liberty to room unrestr icted for a day, a season, or a lifetime. To enjoy the good life.

The terms boat ing and flying have been used for years and can be found in almost all dictionaries. However, the te rm RVing is no t in any dictionary that could be found. Al though this may be true, the te rm RVing is used in many publications i.e., "Guide to Full-time RVing" by Trailer Life, 1982. COMMITTEE ACTION: Accept in Principle.

(l,og # 17) 501C- 8 - (2-2.7.2 Exception (New)): Accept SUBMITTER: Kent Perkins, Recreational Vehicle IndusnTAssoc. COMMENT ON PROPOSAL NO: 501C-8 RECOMMENDATION- Accept original proposal as submitted. SUBSTANTIATION: Pamphle t 58 3-6.2.6 H states: main shu t off valves on a container for liquid and vapor shall be readily accessible without the use of tools, or o ther means shall be provided to shu t off the container valves.

Texas Railroad Commiss ion Division 5 9.175.C states: containers shall be installed in such m a n n e r that access to main shutoff valves is no t h indered by the vehicle 's frame, body, or any eq u ip m en t or appur tenance a t tached or m o u n t e d on the vehicle. This is no t to be cons t rued to prohibi t the installation of containers inside a vehicle's passenger or luggage compar tmen t s where access doors to these

120

N F P A 5 0 1 C - - F 9 2 T C D

compar tments may be locked to secure the vehicle and its contents. Neither code has an 18 in. r equ i r emen t on location of manual

shutoff valve. Propane and natural gas are recognized by E.P.A. and non-

a t t a inment states as d e a n burn ing al ternate fuels. Fleets and gove rnmen t vehicles a~e manda t ed to convert to a clean burn ing fuel. Propane is gaining popularity as an alternate fuel for recreational vehicles as well.

If any motor ized RV manufac tu re r wanted to offer clean burn ing p ropane as an engine fuel, he would install the tank by complying with Pamphle t 58 or the Railroad Commiss ion rules and regulations. He could, in fact, install Ibis tank between the frame rails. The manua l shutoff valve must be accessible, but no 18 in. r equ i r emen t is mandated . Keep in m,tn(t this is liquid service and liquid expands 270 times to vapor. Both codes with safety in mind, consider their installation guidel ines safe.

General Motors and Ford, with safety in mind, install gasoline tanks between frame rails on vans and pickups. A propane tank on a motorized RV would be as safe, if no t safer, between the frame rails even without an additi:mal electronic listed shutoff ~,qlve.

Modern technology and industry experience allows for easier and safer ways to accomplish manual methods .

We feel an accessible vapor service manua l shutoffvalve between tile rails is safe. We would have addit ional safety with the additional electronic normally closed valve that can be shut off f rom inside the coach by loss of power caused by an accident or fire or by a gas leak detector [laving an integl al solenoid shut-off valve activated by the sensor commonly used today in motorized RV's. COMMITTEE ACTION: Accept. COMMITTEE STATEMENT: Al though this proposal was accepted (Voting: 5 yes, 4 no) the commit tee agreed that this c o m m e n t should be sent to the NFPA 58 panel for their inpu t and re~iew.

(Log # 7) 501 C- 9 - (2-2.8.3(a) Exception): Accept in Principle SUBMITTER: James L. Bond, State of Arizona, Office of Manufac- tured Hous ing COMMENT ON PROPOSAL NO: 501C-10 RECOMMENDATION: Revise Exception to 2-2.8.3(a) as follows:

"Entry ~ , d w , , e ~ i t . . . . . . t doors not having windows that open or screens below the level of the ,~as compa r t men t vents or doors to sealed storage compar,:ments. SUBSTANTIATION: 2-2.8.3(a) 1 requires that there be "no openings into the recreational vehicle". If the storage compa r tmen t door is open and the c o m p a r t m e n t is not sealed o f f f rom the vehicles interior, t hen the vehicle does no t mee t the requ i rements of 2-2.8.1 (a) 1.

The r equ i r emen t in the exception for no "windows that open or screens below the gas compa r t men t vent", is a feeble a t tempt to meet the requ i rements of 2-2.8.3(a) 1 in order to allow entry doors within the controlled a.rea, As feeble as it is, it still is an a t t empt to not allow openings into the vehicle. The allowing of unsealed compar tments within the controlled area is a complete disregard of safety. COMMITTEE ACTION: Accept in Principle.

Revise to read ,as follows: Exception: Unventi la ted c o m p a r t m e n t doors containing ei ther

door or body side seals;, and entry doors not containing screens or enable windows below the level of the LP discharge outlet(s). MMITTEE STATEMENT: The commit tee agrees with the

submit ter ' s intent, but the revised language more clearly identifies the criteria for exception.

( L o g # 18) 501(3- 10 - (2-2.8.3(c)): Accept in Principle SUBMITTER: Kent Perkins, Recreational Vehicle Industry Assoc. COMMENT ON PROPOSAL NO: 501C-10 RECOMMENDATION: Revise the first part of the first sentence to read:

"Compar tment , and entry doors no t having windows. . ." . SUBSTANTIATION: This editorial revision better states the intent. C o m p a r t m e n t doors t~pically do not have windows or screens. COMMITTEE ACTION: Accept in Principle. COMMITTEE STATEMENT: See Commit tee Sta tement unde r 501G-9 (Log #7).

(Log # 9) 501C- 11 - (2-4.2(F)): Reject SUBMITTER: Ronald Mell, Marshall Brass Co. COMMENT ON PROPOSAL NO: 501C-11 RECOMMENDATION: Reject original proposal and the Commit tee ' s r e c o m m e n d e d changes. SUBSTANTIATION: Any proposed change in the s tandard should improve safety. There is no th ing in the submit ters substantiation which proves that this change would improve safety. Nor does the commit tees substantiation allowing "Design Flexibility" provide adequate reason for allowing this change, pp. 1-2.3 of 501C requires "Sufficient evidence be submit ted to substantiate any claims made regarding the safety of" alternative materials, pp. 24.2 requires that materials used in the piping s ~ t e m in a recreational vehicle have a mel t ing point of not less than 1,450°F (788°C) and that they "be listed for the specific use intended", pp. 2-4.2 A th rough E lists the acceptable material for use in this application and 2-4.2 F specifically requires that "flexible, non-metallic tubing shall be part of an assembly that is listed for the use in tended." pp. 2-4.12 specifies, again, that materials used for gas connect ions in a recreational vehicle (except as excepted) shall conform to pp. 2-4.2. Nowhere in pp. 2-4.2 is the proposed material referenced. Tile non-metall ic flexible hose and fittings proposed by the submit ter does not comply with any applicable paragraphs in 501C and nei ther the submit ter nor the commit tee have presented the d o c u m e n t e d evidence required by pp. 1-2.3. pp. 2-4.2 (F) allows all the flexibility necessary for use on noi>metallic tubing but is correct in requir ing that the tubing be part of a listed assembly, The proposed change would eliminate the necessity of listing file assembly and wouh ton ly require tha t the componen t s be listed. The proposed change would allow the use of listed componen t s in an application not covered by their listing. This change, if adopted, would not enhance the s.'ffety of the L.P. system of a recreational vehicle and would open the door to the use of "Listed Materials" in applications not covered by their listing. I urge file rejection of tile proposed change to pp. 2-.t.2(F) of 501C and propose the cur rent wording be left as is. COMMITTEE ACTION: Reject. COMMITTEE STATEMENT: The commit tee disagrees with the submit ter ' s substantiation. Listed fittings would address application and installation.

SUBSTANTIATION: This change would be consistent with the title of UL569 "Pigtails and Flexible Hose Connectors for LP-Gas." C O M M I T r E E ACTION: Accept.

(Log # 1) 501C- 14 - (2-6.7.$ (New)): Hold for Fur ther Study SUBMITrER: Douglas MacGregor, Terralab Engineers COMMENT ON PROPOSAL NO: N / A RECOMMENDATION: Add a new paragraph 2-6.7.3 as follows:

"The use of combust ible material as range covers shall no t be allowed." SUBSTANTIATION: T he use o f combust ible materials, with or without metal facings, such as Gorian and Formica, is presendy being allowed if the material has a f lame spread rating o f 25 or less (ASTM E~4) . The ASTM E84 tests the rate of f lame spread, based on a 24-ft

sample length. It is no t a n applicable s t andard for this purpose , since the accidental closing o f the cover with the bu rne r opera t ing generates a kindl ing effect in which the hea ted material will burst into flame.

A low f lame spread index does n o t indicate a non-combust ib le material, bu t o n l y a relative f lame spread rate. The f lame spread rate is immaterial in this application since the typical r ange cover is less than 5 sq ft.

Table 2-6.7.2 does no t allow combustible material this dose to the burners.

Placing a combust ible material in this type o f an ignition si tuation could easily cause it to becomes the ignition source for a construction-wide c o n f l a g ~ tion. COMMITTEE A-CTION: Hold for Fur ther Study. C O M M I T r E E STATEMENT: No proposal was submi t ted on 2-6.7.$ in the TCR and the Commit tee considers this to be new material. Also, the commit tee wants to review this issue further . T he submit ter indicated he had submi t ted a TIA on this issue to NFPA, but stated he would forward a letter into Mr. Cote request ing a 90 day q~old" on the TIA unt i l addit ional investigation and research could be completed.

"One exit mus t communica t e direcdy to the exterior f rom the bedroom or s leeping area." SUBSTANTIATION: Per the cur ren t code, the exits in the bedroom are acceptable. However, in the living room area the pa th to the second exit is passing the first exit and is ~ e r e f o r e not acceptable.

The in tent of this section is to safely evacuate persons f rom the un i t in case of an emergency. To achieve this, e a c h b e d r o o m should have a direct m e a n s of exit to the exterior of the unit. With the addit ion of this r e q u i r e m e n t and a reasonable interpreta t ion of s leeping area as a r o o m instead o f the bed plus 6 1 / 2 in. would resolve the issue. It should be no ted tha t tile word bed room and sleeping area are used as equals in the code.

Sleeping area mus t be considered grea te r t han the bed and 6 1 /2 in. location where your feet hi t t he floor. In the code bedroom and sleeping area are equal. Per the cur ren t code, the exits in the bed room are acceptable.

However, in the living room area the pa th to the second exit is passing the first exit a nd is therefore no t acceptable.

The intent of this section is to safely evacuate persons f rom the un i t in case of an emergency. To achieve this, each bed room should have a direct m e a n s of exit to the exterior of the unit. With the

addit ion o f this r e q u i r e m e n t a n d a reasonable interpretat ion of s leeping area as a r o o m instead of the bed plus 6 1 /2 in. would resolve the issue. It should be no ted tha t the word bed room an d sleeping area are used as equals in the code. COMMITTEE ACTION: Accept in Principle. Add to the end of the last sentence: " . . . except when any part of a bed in its normal s leeping configura-

t ion is within 24 in. of the neares t des ignated exit." COMMYI'IT.E STATEMENT: T h e revisions address the submit ter ' s concerns bu t keeps the exist ing requ i rements intact.

(~69 610 ram) a n d a m ino r axis o f ~ 17 in. (~0~- 452 ram). (See Appendix A, Figure A-3-2.5.) An exterior passage door if used for an al ternate exit shall provide an unobs t ruc ted open ing with a m i n i m u m horizontal d imens ion of 18 in. (457 ram) and a m i n i m u m vertical d imens ion of 48 in. (1.2 In). SUBSTANTIATION: An open ing of 15 in. by 22 in. is n o t a sufficient open ing of unohs t rnc ted passage for the average person, especially u n d e r the condi t ion of emergencies which causes confusion and panic.

The documen t s submi t ted are for substant iat ion for the reques ted change to 501C Section 3-2.5. The re are two parts to the substantia- t ion as follows:

(Log # 15) 501C- 19 - (3-4.1): Accept in Principle SUBMITTER: Michae lHannah , Nat'l RV Inc. COMMENT ON PROPOSAL NO: 501G-25 RECOMMENDATION: In 3-4.1 change to "5 B:C Fire Extin- guisher." SUBSTANTIATION: The 5 B:C fire extinguisher is more readily available than the 4 B:C. The 10 B:C is inappropriate due to weight and size. It is difficult for some people to use the 10 B:C due to their age and strength. The size of the 10 B:C makes it very difficult if no t impossible to install it within the requirements of other codes and its listing in the confined spaces in a P~V.. And third in an accident a 10 B:C fire extinguisher can become a deadly projectile because of its size and weight it has a serious installation and securing problem. We feel the safety hazards created by the size and weight of the

10 B:C fire extinguisher far exceed the possible benefits of it discharging more agent. The 5 B:C Fire Extinguisher is without a doubt the safest choice. COMMITI'EE ACTION: Accept in Principle. COMMITrEE STATEMENT: See Committee Action under 501C-20 (Log #14).

(Log # 14) 5OlG- 20 - (3-4.1): Accept SUBMITTER: Robert E. Wozniak, Fleetwood Enterprises, Inc. COMMENT ON PROPOSAL NO: 501C-25 RECOMMENDATION: Accept the original proposal for 5 B:C fire extinguisher (F/R), reject the committee 's recommendat ion for a 10 B:C. SUBSTANTIATION: The 501C standard is to address min imum safety requirements. This proposal was submitted to reflect that 4 B:C fire extinguishers were no t available but that 5 B:C fire extinguishers were. Without justification or documented need, the committee decided to double the size of the fire extinguisher based upon bigger was better.

NFPA 10, Appendix A, A-l-4.1 states, in part, that "Portable fire extinguishers are appliances to be used by the occupants of a fire- endangered building or area. They are primarily of value for immediate use on small fires." As such, the 5 B:C should remain the minimum standard size until justification or documented need shows differently. COMMITrEE ACTION: Accept.

(Log # 22) 501C- 21 - (3-4.5): Accept in Principle SUBMITTER: Kent Perkins, Recreational Vehicle Industry Assoc. COMMENT ON PROPOSAL NO: 501C-33 RECOMMENDATION: Revise existing text to read:

"All RVs equipped with .%cI ba~ .h .g cq~;t. , . .c,~ br designed with features to accommodate future installation of ~ach cqa;v,,~c..~ an internal combustion engine shall be installed with a listed CO detector installed in accordance with its listing. TL;~ ,c.t..L ~...~.,t ~:~,dl .~,A be,.,, . . . . ,.ff~,xi,~ u..dl .gcv;.,.,~L,., 1, 1L'33." SUBSTANTIATION: The intent of the original submitter of the dProposal that resulted in the current language was to require CO

etectors in RVs which contained or were designed to contain generators. To require a CO detector in any RV containing fuel burning equipment is far beyond the original intent, and would cause CO detectors to be required in virtually every RV. The concerns stated by the NFPA Committee were that the generator set is not the only source of CO. The source could be adjacent vehicles or internal LP gas appliances, ff the concern is RV interior LP gas appliances creating CO, NFPA 501C contains many requirements to address this potential problem. Appliances are required to be of the direct-vent type and must provide complete separation of the combustion system from the interior a tmosphere of the recreational vehicle (2-6.2.2). LP gas appliance vent terminations must be at least 3 ft f rom any motor driven air intake into the vehicle (2-6.3.3). Fuel burning cooking appliances must have a specific amount of venting to the exterior provided within a specified distance (2-6.3.4). Regard in~the potential for CO from adjacent vehicles this is a valid concern, ou t one that can be present in many situations besides RV

kS. (A crowded freeway for example.) Requiring CO detectors in that contain an internal combustion engine (primary mover

engine or generator) or are designed to have a generator installed later wouldprovide protection for the types of RVs that have had documen t edp rob l ems with CO in the past, and would accomplish the intent of the original submitter. Until a CO detector becomes standard equipment in automobiles and homes, to require one in virtually every RV made is overkill. COMMITrEE ACTION: Accept in Principle.

Revise first sentence to read: " A l l RV's equipped with an internal combustion engine or designed

with features to accomodate future installation of an internal combustion engine shall be equipped with a listed CO detector installed in accordance with its listing."

Delete last sentence talking about effective date of September 1, 1993. COMMI'ITEE STATEMENT: The revised language makes the proposed change read more clearly.
