NFPA Standard Explorer

Performance and certification requirements for personal alert safety systems (PASS). PASS devices detect firefighter immobility and emit an audible alarm to aid rescue—NFPA 1982 establishes minimum signal output, activation, and durability standards.

PASS alarm activation is a critical Mayday signal trigger. Devices that fail to activate, produce insufficient volume, or are worn without activation have been identified in LODD investigations. Consistent PASS activation discipline—every entry, every time—is a non-negotiable habit supported by proper maintenance.

• Minimum alarm signal strength and tonal characteristics (conceptual)
• Automatic activation motion-sensing concepts (high level)
• Manual activation requirements and interface design concepts
• Environmental durability and heat resistance concepts
• Integration with SCBA unit concepts (integrated vs. stand-alone PASS)
• Certification and labeling requirements

• Verifying PASS device activation before every interior assignment
• Incorporating PASS alarm recognition drills into annual SCBA training
• Coordinating PASS maintenance with SCBA service intervals
• Training RIT/RIC members to locate a PASS alarm signal in zero-visibility conditions
• Post-incident review: was PASS activated, did it alarm, was it audible to RIT?

• PASS activates automatically, so manual activation isn't needed (manual activation should always be a habit—automatic backup, not primary).
• You can hear a PASS anywhere on the fireground (noise, distance, and building construction significantly reduce alarm range).
• A beeping PASS means someone is OK (a manual alarm could indicate a conscious firefighter in distress).

• Make 'PASS ON' a mandatory verbal part of the accountability process at every entry
• Run PASS alarm recognition drills: can your crew locate a PASS signal in smoke conditions?
• Include PASS in post-incident SCBA inspection to confirm it was activated and functioned
• Establish a PASS replacement/inspection cycle tied to SCBA service records
