What type of gear is NFPA 2112 concerned with?

NFPA 2112 specifically addresses protective clothing designed for use in environments where there is a risk of exposure to flame and thermal hazards, which is often referred to as flash fire. The standard establishes requirements for the design, performance, labeling, and use of protective garments that are intended to provide a minimum level of protection for workers in industries where they may encounter such hazards. Therefore, gear that is compliant with NFPA 2112 would be categorized as flashover or flame-resistant gear, intended to protect against sudden bursts of flame and the heat from fire, making it specifically related to the type of hazard that can lead to flashover situations.

The other options refer to different types of protective gear addressing other specific hazards. Protective clothing for electrical hazards and chemical-resistant gear serve entirely different purposes, focusing on risks associated with electrical exposure and chemical exposure respectively, while high-altitude safety gear pertains to fall protection and safety measures necessary for operations at height. Each set of gear is designed to meet specific standards and protect against unique risks, making NFPA 2112's focus on flame and thermal hazards distinct from the others.
