Which NFPA standard governs protective ensembles for first responders in hazmat situations?

• A. NFPA 1994
• B. NFPA 1991
• C. NFPA 1992
• D. NFPA 473

Answer: (A)

Protective ensembles for first responders at hazmat scenes are governed by a standard that specifies the clothing and ensembles emergency responders wear to protect the body during hazmat operations. NFPA 1994 sets the requirements for these protective clothing ensembles, including design, materials, performance, and labeling, so responders can select appropriate protection for the hazards they may face at the scene. The other standards cover different levels or aspects of protection: NFPA 1991 addresses vapor-protective ensembles for airborne hazards, NFPA 1992 covers liquid-splash protective ensembles for splash risks, and NFPA 473 relates to the competencies and training of hazmat responders. Because the question focuses on the protective clothing ensemble itself for first responders, NFPA 1994 is the correct standard.
