NFPA 1991 presents requirements for the highest level of protection for emergency responders to hazardous materials incidents where an unknown threat, a vapor threat, or a chemical or biological terrorism WMD threat is present or expected. Provisions cover the design, performance, testing, documentation, and certification of vapor-protective ensembles and ensemble elements used by emergency response personnel during hazardous materials incidents -- and for protection from chemicals, biological agents, and radiological and nuclear particulates (CBRN) encountered as terrorism agents. Additional optional criteria for escape protection from chemical flash fires encountered during hazardous materials incidents are also provided.
Changes in NFPA 1991 help fire service leaders and jurisdictions do more to protect personnel.
Adopted by the U.S. Department of Homeland Security (DHS) in its 2005 edition, and updated for the equipment and materials in use today, NFPA 1991 is an essential resource for fire service leaders and purchasers, Authorities Having Jurisdiction (AHJs), and manufacturers.
