NFPA 2113 Standards to Ensure Accurate Selection and Maintenance
Standard on Selection, Care, Use, and Maintenance of Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire
Purpose: The purpose of the NFPA 2113 standard shall be to reduce the health and safety risks associated with the incorrect selection and use of flame-resistant garments and those risks associated with incorrectly maintained, contaminated, or damaged flame-resistant garments.
Scope: The NFPA 2113 standard shall specify the minimum selection, care, use, and maintenance requirements for flame-resistant garments for use by industrial personnel in areas at risk from flash fires or short-duration flame exposure that are compliant with NFPA 2112, Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire.
Frequently Asked Questions:
Under NFPA 2113 is a hazard assessment really necessary?
Under NFPA 2113, a hazard assessment must be conducted that will deliver a quantified energy level for the various tasks that workers perform. To properly conduct a hazard assessment the following are critical questions to be answered:
- What materials are burning? Or What is your fuel source?
- How much air is available to mix with the fuel to support combustion?
- How long will it take for a person to identify they are in trouble and do something about it?
- Are workers wearing gear that would slow them down?
Isn't knowing the duration of the fire critical in selecting the proper thermal personal protective equipment (PPE)?
Knowing the duration of a fire is usually important in understanding potential damage to infrastructure and fire escalation factors (as has occurred in large industrial incidents). However, for the selection of PPE it is the duration of the potential thermal exposure a person might experience during escape that’s important. This is normally determined through a site and task hazard analysis. Several tools can assist in this process. The Center for Chemical Process Safety of the American Institute of Chemical Engineers (CCPS) and the NFPA 2113 standard have been recognized by OSHA as guides to assist in this process and to select the appropriate thermal protective PPE.
NFPA 2113 refers to “Flash” fires, Are “Flash” fires the only industrial fire hazard that can cause burn injury?
No. There are many other fire hazard risks in process industries that work with or handle flammable materials. These fire hazards occur from unplanned equipment failures that release, with subsequent ignition, process gasses, liquids, and solids from spills or pressurize line breaks. Many of these fires begin when a flash, or vapor cloud fire burns back to the source of the release. Overall, industrial fire hazards are generally classified as:
- vapor cloud fires, with:
a) no explosion,
b) resulting from explosion, and
c) resulting in explosion,
- fireballs (instantaneous release and ignition of liquefied gas above boiling point),
- jet flames (directed fire from flammable materials escaping under pressure),
- flammable liquid fires, forming one or both:
a) pool fires, and
b) running liquid fires,
- solids fires, in the form of:
a) dust fires, or
b) fires of solid materials (i.e., pyrophoric metals),
- structural fires (i.e., fires of warehouse, office, and support buildings), and
- fires associated with oxygen.
