Study Notes
Post-Incident Air Monitoring
- The Incident Commander (IC) or Safety Officer is responsible for air monitoring after a fire.
- All firefighters must wear full PPE, including SCBA until authorized by Command to remove them based on air monitoring results.
- Air monitoring begins when the IC deems it appropriate.
- Once the fire is extinguished and ventilation is complete, the IC will request air quality monitoring to ensure 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.
Respiratory Protection Removal Criteria
- Respiratory protection can only be removed if CO levels are less than 35 ppm, HCN levels are less than 4.7 ppm, O2 levels are between 19.5% and 23%, and VOC levels are less than 100 ppm.
- The atmosphere in the structure must be monitored and rechecked every 15 minutes after SCBA is removed.
- The IC or Safety Officer may require personnel to wear breathing protection at any time, regardless of air quality levels obtained.
Additional Information
- The guideline does not preclude a firefighter from wearing respiratory protection at any time.
- If oxygen levels are less than 20.9%, the IC should determine why the levels are low and what may be displacing the oxygen.
- This guideline applies to all members.
- It is important to note that skin contact with contaminated materials can lead to overexposure, even if air levels are below recommended limits.
