What does NFPA 1981 specifically address?

NFPA 1981 specifically addresses the standards for open-circuit self-contained breathing apparatus (SCBA) used by firefighters. This standard outlines the performance requirements, testing protocols, and certifications necessary to ensure that SCBAs provide adequate respiratory protection in environments that may be immediately dangerous to life or health.

The emphasis on open-circuit SCBAs is crucial because these devices allow firefighters to breathe clean air from a tank while providing protection from smoke, toxic gases, and hazardous atmospheres encountered at fire scenes. Understanding the standards defined in NFPA 1981 helps ensure that firefighters are equipped with reliable and effective breathing apparatus to perform their duties safely.

While the other options mention related topics in firefighting, they do not specifically cover the details and requirements set forth for open-circuit SCBAs, which are critical for ensuring the safety and well-being of firefighters operating in hazardous conditions.
