Public Comment No. 4-NFPA 495-2016 [ Section No. 5.2.8.1 ]

5.2.8.1 Type of Clothing.

Clothing to be worn by persons involved in the manufacturing process shall be of a type approved by management or the AHJ.

Statement of Problem and Substantiation for Public Comment

The issue with just allowing management approving use of the type of clothing worn is dealing with the management hazard of cost priority over personnel safety. In addition, the authority having jurisdiction over explosive safety at the site is sometimes not in a managerial position. Adding the option of getting approval from the authority having jurisdiction would provide enhanced safety of personnel and avoid the management hazard of buying non-compliant protective clothing due to costs.

The so called 8 millisecond rule was promulgated in response to the understood

inaccuracies of pyrotechnic initiation systems to try to reasonably provide separation of

delayed charges with the hope that at minimum holes would be less likely to sequence

out of order. Research and technology has proven in most cases with such systems eight

ms is not enough (see Lusk research test data graphic). With the advent of precise

electronic initiation systems as little 1ms of separation (for small near field charges) is

adequate to separate wave arrival. The wave cancelling benefits (destructive interference)

derived from signature analysis are dependent on precise (often less than 8ms) separation

of charges. Preserving the 8ms rule for electronic systems handicaps their effective use

and thereby presents a barrier to more wide spread introduction of this technology. More

importantly, when charges are reduced, they are by technical necessity spatially scaled

smaller. The timing interval must also reflect the same scaling in order to prevent an

under-confined detonation or destructive transient communication between closely

spaced charges. Forcing blast design outside recognized industry spatial relationship

standards, not only inhibits effective use of technology but could generate misfires or fly-

rock. At best, the eight millisecond reference has no technical basis that can provide any

substantiated benefit for design application when using precise initiation systems. At

worst, based on experience, insistence on its application to spatially scaled applications

presents a serious safety risk.

Public Comment No. 7-NFPA 495-2016 [ Section No. A.5.3.1 ]

A.5.3.1

The hazard classification, for example, Division 1.1, 1.3, and so forth, of explosive materials when packaged for transportation or storage could be different from the hazard classification for these same materials as the materials are moving within the manufacturing process. The differences in classification can be due to quantity or mass of material present, its physical form, the configuration (or arrangement) of the material, as well as other extrinsic or intrinsic factors. An in-process hazard classification is used to characterize the hazards of a given material as it exists outside of its packaging within the manufacturing process.

The hazard classification of high explosion hazard materials is generally considered to be the most severe. Materials that are known to have a high explosion hazard are treated as those that mass explode. The classification code allows the user to assume that the material presents a high explosion hazard, or to demonstrate that the in-process hazard classification is other than a high explosion hazard, through documentation, experience with a given process, or testing. An example of each method of demonstration is as follows:

(1) A documented method of demonstration can include explosives that are manufactured to a published military standard, or explosives manufactured to another established process that is documented by qualified operating procedures. To be qualified, the procedures should assign an in-process hazard classification that can be demonstrated, or a high explosion hazard classification can be assumed.

(2) An example of experience with a given process can include a process, equipment, and procedures that have been used by multiple manufacturers over a prolonged period of time so that there is an ample database with which to establish the incident history of the manufacturing process as to its hazards.

(3) By testing with an agreed-upon protocol, an in-process hazard classification can be assigned to one or more steps in the process.

The hazard classification of packaged explosive materials might vary as the material is removed from the original shipping container for use in an assembly operation. Similarly, the hazard classification for materials that are in the process of being formulated might vary and the hazard classification of the bulk form of the material can be quite different from that of the same material in its packaged state. The hazard classification of some materials can be said to be “package dependent,” with the hazard classification subject to change depending on the type or construction of the packaging used as well as the quantity contained within the package.

An analogy can be made between packaged materials and unpackaged materials that are being handled in processing operations through the use of mechanical equipment such as mixing, blending, or formulation processes. The quantity of material used and the shape of the containers (or configuration) that includes the physical dimensions can all have a bearing on the hazard classification of the material. The critical mass (critical height, and/or critical diameter) is frequently used as a measure of safety in establishing the parameters of the manufacturing process.

The intrinsic chemical or physical properties alone of a material can determine the hazard classification, or the hazard classification can be influenced by extrinsic factors such as temperature, pressure, arrangement, or the mechanical aspects of the process operations. Various methods can be used to establish the in-process hazard classification for the materials being manufactured or used within the manufacturing process. Some materials might have well-established process parameters where the nature of the process and the nature of the formulations have long been known. Other materials or processes to which the materials are exposed could be new, or the methods or equipment in which they are to be manufactured or handled are either new or outside of the established parameters. In all cases, an in-process hazard classification for the material being manufactured or used is required. When decisions are made regarding the siting, occupancy, or use of a building in which manufacturing occurs, it is critical that each step of the manufacturing process be evaluated so that the appropriate in-process hazard classification is assigned. The appropriate building location can then be established, and the area of the building being utilized can be assigned the proper occupancy classification.

When testing is used to establish the hazard classifications, tests defined by the Department of Defense (DOD), the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), United Nations Transport of Dangerous Goods (UN), or Department of Transportation (DOT) are generally used. Regardless of the specific tests being performed, the protocol as well as the acceptance criteria should be agreed upon between the user and the AHJ. Figure A.5.3.1(a) and Figure A.5.3.1(b) provide examples of a test protocol in which the in-process hazard classifications of materials are established by testing. Figure A.5.3.1(a) is used for the in-process classification of substances, and Figure A.5.3.1(b)c is used for the in-process classification for unpackaged articles. These figures and additional information can be found in the Explosives Testing Users Group (ETUG) Standard entitled: In-Process Classification of Explosives Standard: ETUG-GS01-15, 2015.

Public Comment No. 3-NFPA 498-2016 [ New Section after 4.1.2 ]

TITLE OF NEW CONTENT

Under no circumstances shall any safe haven be selected that is located within 1500 feet of a school or hospital.

Statement of Problem and Substantiation for Public Comment

The Technical Committee should address the proposed change to add additional separation distance between the Safe Haven and critical infrastructures containing children in a school room setting or hospitals that may contain individuals that would be difficult to move in case of an incident at the lot. An additional consideration for the committee would be add senior living or assisted living facilities for the same reason. Related Item Committee Input No. 1-NFPA 498-2016 [Section No. 4.1.2]

4.2.1.1

Before any vehicle is admitted to a safe haven, a thorough inspection shall be made of the vehicle. This inspection should be carried out by the driver(s) who are very familiar with the vehicle and its condition.

Statement of Problem and Substantiation for Public Comment

The current language in NFPA 498 Section 4.2.1.2 requires that a vehicle be inspected before it is allowed into the Safe Haven. This clarification states who shall do the inspection stipulated in the 2013 edition of NFPA 498.
