Proficiency in Gas Detection Urged for All Firefighters
A recent article highlighted in the fire service community is urging all firefighters, not just hazmat specialists, to master gas detection equipment and protocols. The piece argues that understanding atmospheric monitoring is a fundamental tactical skill essential for safety at a wide range of incidents, including routine medical calls and structure fires. This reflects a push for broader skill sets among fire service personnel.
- The overhaul phase of a fire, when crews search for hidden embers after the main blaze is extinguished, presents a significant atmospheric hazard; a 2017 NIOSH investigation found a 54-year-old fire captain died from carbon monoxide toxicity after collapsing during overhaul operations. - Beyond visible smoke, structure fires produce a hazardous mix of invisible gases, most notably carbon monoxide (CO) and hydrogen cyanide (HCN), often called the "toxic twins." These two chemical asphyxiants interfere with the body's ability to use oxygen and are a primary cause of death from smoke inhalation. - The increased use of synthetic materials in modern construction and furnishings has led to a higher prevalence of hydrogen cyanide (HCN) in structure fires; HCN exposure can cause dizziness and confusion, potentially leading to firefighters making life-threatening errors. - Gas detection is also a critical tool for safety on routine medical calls. Emergency responders often use personal carbon monoxide monitors when entering a residence for a medical emergency to rule out the "silent killer" as the cause of a patient's vague, flu-like symptoms. - In one documented case, a crew responding to a report of heat exhaustion used a noninvasive carbon monoxide detector on the patient, which revealed a reading of 9% carboxyhemoglobin; this prompted a wider search of the factory, where crews found CO levels as high as 556 ppm and evacuated over 100 employees. - The Seattle Fire Code mandates the installation of carbon dioxide detection and alarm systems in commercial facilities where CO2 is stored or used, with alarm thresholds set at 5,000 parts per million. - National Fire Protection Association (NFPA) 1500, the Standard on Fire Department Occupational Safety, Health, and Wellness Program, requires that all fire department facilities have carbon monoxide detectors installed in sleeping and living areas.
