What standard is referenced for extinguishers in terms of efficacy and performance?

The correct reference for the efficacy and performance standards of fire extinguishers is ANSI/UL626. This standard specifically addresses the testing requirements, performance, and safety features of portable fire extinguishers. It ensures that the extinguishers are reliable and function as intended when needed during a fire emergency.

This standard outlines the criteria for different types of extinguishers, evaluating their ability to suppress various classes of fires, which ensures consistent performance across products. By adhering to ANSI/UL626, manufacturers can guarantee that their extinguishers meet necessary safety and effectiveness benchmarks for consumer use.

The other options do not specifically focus on extinguishers. NFPA 101 (Life Safety Code) deals more with building safety and occupancy, NIOSH focuses on occupational safety and health, and OSHA 1910 sets forth general industry safety standards but does not specifically target fire extinguisher performance.
