    Study Notes

    Air Monitoring Guideline

    • The Incident Commander (IC) or Safety Officer is responsible for implementing air monitoring procedures.
    • All firefighters must wear full Personal Protective Equipment (PPE), including SCBA, until authorized by Command.
    • Air monitoring for Immediately Dangerous to Life or Health (IDLH) atmospheres will begin when the Incident Commander deems it appropriate.
    • After 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.
    • 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%, and VOC levels are less than 100 ppm.
    • Once the IC or Safety Officer determines SCBA is no longer required, the atmosphere must be monitored and rechecked every 15 minutes.
    • The guideline does not prevent firefighters from wearing respiratory protection at any time.
    • The IC or Safety Officer may require personnel to wear breathing protection regardless of air quality levels.

    Purpose and Scope

    • The purpose of the guideline is to establish procedures for monitoring CO, HCN, and O2 levels in structure fires to determine when respiratory protection is no longer required.
    • The guideline applies to all members of the fire department.

    Exposure Limits

    • For respiratory protection to be removed, the following exposure limits must be met:
      • CO: Less than 35 parts per million (ppm)
      • HCN: Less than 4.7 ppm
      • O2: Greater than 19.5%, but less than 23%
      • VOCs: Less than 100 ppm
    • These are air level limits only. Skin contact can lead to overexposure even if air levels are below the limits.

    Oxygen Levels

    • If oxygen levels are less than 20.9%, it is advisable to determine the cause and potential oxygen displacement.

    Additional Notes

    • The guideline does not preclude a firefighter from wearing respiratory protection.
    • The IC or Incident Safety Officer may require personnel to wear breathing protection at any time.
    • Contact the appropriate contact office for questions or comments on the guidelines.

    Post-Incident Air Monitoring

    • The Incident Commander (IC) and/or Safety Officer is responsible for monitoring air quality during and after incidents.
    • Firefighters must wear full Personal Protective Equipment (PPE) including SCBA until authorized by the Incident Commander based on air monitoring results.
    • Air quality monitoring for Immediately Dangerous to Life or Health (IDLH) atmospheres will start when the Incident Commander deems it appropriate.
    • After the fire is extinguished and ventilation is completed, 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 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%, and VOC levels are less than 100 ppm.
    • The atmosphere must be monitored and rechecked every 15 minutes after SCBA is deemed unnecessary by the IC or Safety Officer.
    • The Incident Commander or Safety Officer may require personnel to wear breathing protection at any time, regardless of the air quality levels obtained.
    • If 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.

    Post-Incident Air Monitoring

    • The Incident Commander (IC) and/or Safety Officer is responsible for air monitoring.
    • All firefighters must wear full Personal Protective Equipment (PPE), including SCBA, until authorized by Command based on air monitoring.
    • Air monitoring will begin when the IC deems it appropriate.
    • After the fire is extinguished, the IC will request air quality monitoring to ensure safe operational limits per NIOSH standards.
    • Multi-gas meters and HCN meters will be used to assess air quality.
    • 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 (if equipment is available).
    • The atmosphere must be monitored and rechecked every 15 minutes after SCBA is no longer required.
    • Firefighters are not prohibited from wearing respiratory protection at any time.
    • The IC or Safety Officer may require personnel to wear breathing protection regardless of air quality.
    • If oxygen levels are less than 20.9%, further investigation is advised.

    Incident Commander (IC) and Air Monitoring Responsibility

    • The Incident Commander (IC) and/or Safety Officer are responsible for implementing the air monitoring process in fire incidents.
    • The IC determines when the air monitoring process for Immediately Dangerous to Life or Health (IDLH) atmospheres begins.

    Full PPE Requirements During Fire Incidents

    • All firefighting personnel must wear full Personal Protective Equipment (PPE) including Self-Contained Breathing Apparatus (SCBA) until authorized by Command.
    • Command's authorization to remove SCBA is based on air monitoring results.

    Post-Fire Air Monitoring for Safe Operations

    • After the fire is extinguished, the IC requests air quality monitoring in the structure.
    • Air quality monitoring includes measuring CO, HCN, O2, and VOC levels.
    • Monitoring is conducted to ensure levels meet safe operational limits per NIOSH standards.

    SCBA Removal Criteria and Monitoring Frequency

    • 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%, and VOC levels are less than 100 ppm.
    • The atmosphere in the structure must be rechecked every 15 minutes after the IC authorizes SCBA removal.

    IC Discretion and Firefighter Safety

    • The IC or Safety Officer can require personnel to wear breathing protection at any time, regardless of the air quality levels obtained.
    • Firefighters are not precluded from wearing respiratory protection at any time.
    • If oxygen levels are less than 20.9%, the cause of displacement should be investigated.
