    Study Notes

    Post Incident Air Monitoring

    • The Incident Commander (IC) or Safety Officer is responsible for implementing the air monitoring process.

    • All firefighters must wear full Personal Protective Equipment (PPE), including SCBA, until authorized by the IC to remove it 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 completed, the IC will request air quality monitoring to ensure it meets safe operational limits per NIOSH standards.

    • Multi-gas meters and HCN meters should be uses to monitor air quality in all areas of the structure.

    • Respiratory protection can be removed only if:

      • CO levels are less than 35 ppm
      • HCN levels are less than 4.7 ppm
      • O2 levels are between 19.5% and 23%
      • VOC levels are less than 100 ppm

    • Once the IC or Safety Officer determines that SCBA is no longer required, the atmosphere in the structure must be monitored and rechecked every 15 minutes.

    • The guideline does not preclude a firefighter from wearing respiratory protection at any time, and the IC or Safety Officer may require personnel to wear breathing protection, regardless of air quality levels.

    Purpose

    • To establish guidelines for monitoring Carbon Monoxide (CO), Hydrogen Cyanide (HCN), and Oxygen (O2) levels in structure fire buildings to determine when respiratory protection is no longer required for firefighter safety.

    Policy Statement

    • All members must comply with this guideline.

    Scope

    • This guideline applies to all members.

    Responsibilities

    • The Incident Commander (IC) and/or Safety Officer are responsible for implementing the air monitoring process.

    • All members are to wear full Personal Protective Equipment (PPE) including SCBA until authorized by Command to doff them, based in part on air monitoring results.

    • When the incident is deemed safe by the IC or Safety Officer, the atmosphere in the structure will be monitored and rechecked every 15 minutes.

    Requirements for Removing Respiratory Protection

    • CO levels must be less than 35 ppm.

    • HCN levels must be less than 4.7 ppm.

    • O2 levels must be greater than 19.5% but less than 23%.

    • VOCs must be less than 100 ppm (monitor if equipment is available).

    • These exposure limits are for air levels only. If skin contact also occurs, you may be overexposed, even though air levels are less than the listed limits.

    Other Notes

    • If the oxygen levels are less than 20.9%, it is advisable to determine why the levels are low and what may be displacing the oxygen.

    • This guideline does not preclude a firefighter from wearing respiratory protection at any time.

    • The IC or Incident Safety Officer may require personnel to wear breathing protection at any time, regardless of the air quality levels obtained.
