What standard governs the Open-Circuit Self-Contained Breathing Apparatus for fire and emergency services?

The standard that governs Open-Circuit Self-Contained Breathing Apparatus (SCBA) for fire and emergency services is NFPA 1981. This standard establishes the minimum requirements for the performance, design, testing, and certification of SCBA that firefighters use in hazardous environments. Adhering to NFPA 1981 ensures that these breathing apparatuses provide adequate protection for users in smoke-filled or toxic atmospheres while allowing them to perform their duties effectively.

For those studying or working in fire safety, understanding this standard is crucial for ensuring the safety and operational efficiency of personnel in emergency situations. The other options listed refer to different standards that cover other types of equipment or components related to fire service operations, but they do not specifically address SCBA requirements.
