    Study Notes

    Fire Department / Harris County ESD No. 7 - Carbon Monoxide Monitoring

    • Standard Operating Line (SOL) SFD.012, Revision 2, was issued on July 17, 2024, and will be reviewed on July 1, 2025.
    • The SOL is applicable to all members who may work with CO monitoring equipment.
    • The Fire Department is responsible for determining if a CO problem exists and providing emergency medical care if needed.
    • To determine the presence of CO, several steps are involved:
      • Prepare the instrument: Ensure the CO monitor is functioning and select an appropriate multi-gas instrument that measures at least O2 and CO.
      • Sample outside air: Take a reading away from the structure and vehicles to establish a background reading.
      • Initial Occupant Contact: Immediately evacuate the structure and call for a medic unit if anyone displays symptoms of CO poisoning (headaches, nausea, vomiting, disorientation).
      • Test oxygen (O2) content inside the structure: If below 19.5%, SCBA must be used by all personnel entering the structure.
      • Check areas related to the suspected source:
        • Gas-fired appliances: Inspect all furnaces, boilers, space heaters, and gas water heaters for proper flue connection and operation.
        • Gas clothes dryer: Inspect for proper flue connection and take readings while it operates.
        • Fireplace: Take a reading in front of the hearth and ensure proper drafting and flue unobstruction.
        • Other possible sources: Investigate potential CO production from sources like smoking, auto engine exhaust, grills, etc.
      • Document all readings and locations in applicable reports.
    • If high CO readings are obtained:
      • Notify the gas company if readings exceed 10 ppm in residential structures and 35 ppm in commercial/industrial structures.
      • Shut off the fuel supply if the source can be easily identified.
      • Ventilate the building as necessary.
    • CO detectors in residence:
      • Recommend occupants check their detectors according to manufacturer instructions.
      • Fire personnel should not disconnect or deactivate any homeowner-owned CO detectors.
    • CO is an odorless, tasteless, colorless gas that can be deadly.
    • Many home appliances can produce CO under faulty conditions, and the source may not always be easily detectable.
    • This SOL clarifies the responsibilities and procedures of the Fire Department in responding to potential CO incidents, ensuring both public safety and appropriate emergency response measures.

    Carbon Monoxide Information

    • CO is odorless, tasteless, and colorless.
    • It is a byproduct of combustion or fuel-burning.
    • CO can cause symptoms that mimic the flu, unconsciousness, and even death.
    • Many appliances around the home can produce CO.
    • Since the source may be transient in nature, the source may not always be detectable.

    Executive Summary

    • Fire Department personnel must assess the presence of CO, provide emergency medical care and evacuate the structure
    • CO monitors should be functional and suitable for multi-gas measurement
    • If occupants display symptoms of CO poisoning, a medic unit must be called
    • Areas near suspected CO sources (furnaces, appliances) must be checked for CO levels
    • Homeowners should check their CO detectors as per the manufacturer’s recommendations
    • CO is odorless, colorless and tasteless, posing a serious health risk
