There are a large number of complex chemical occupational hazards present at the fire investigation site,posing a great threat to the occupational safety and health of fire investigators.To achieve the monitoring of chemical occupational hazards at the fire inspection site,the type and concentration of gas detected were determined through hazard factor identification.A portable gas analyzer was designed using gas sensor array technology,and the detection effectiveness of the gas analyzer was verified using standard gases and material pyrolysis to produce smoke.The results indicated that the portable gas analyzer can detect the concentration of mixed acute and chronic toxic gases and inhalable particulate matter,providing reference for the assessment and protection of chemical occupational hazards for fire control personnel.
