Study Notes
Post-Incident Air Monitoring
- The Incident Commander (IC) or Safety Officer is responsible for air monitoring.
- All firefighters must wear full PPE including SCBA until authorized by Command based on air monitoring results.
- Air monitoring for Immediately Dangerous to Life or Health (IDLH) atmospheres will begin when the IC deems it appropriate.
- After the fire is extinguished and ventilation is complete, the IC will request air quality monitoring to confirm levels meet safe operational limits per NIOSH standards.
- Multi-gas meters and HCN meters will be used to monitor air quality in all areas of the structure.
- For respiratory protection to be removed, all of these criteria must be met:
- CO levels must be less than 35 ppm.
- HCN levels must be less than 4.7 ppm.
- O2 levels must be between 19.5% and 23%.
- VOC levels must be less than 100 ppm (if equipment is available).
Air Monitoring After SCBA Removal
- The IC or Safety Officer will recheck the air quality in the structure every 15 minutes after SCBA removal.
- This guideline does not preclude a firefighter from wearing respiratory protection at any time.
- The IC or Safety Officer may require personnel to wear breathing protection regardless of air quality levels.
- If oxygen levels are less than 20.9%, investigate the cause and potential oxygen displacement.
Responsibilities
- Every member must comply with this guideline.
- The IC and/or Safety Officer implement the air monitoring process.
