What is a combustible gas indicator (CGI)?

• A. A device that detects radiation levels
• B. A device that measures the concentration of flammable gases
• C. A portable unit for emergency lighting
• D. A temperature sensor for hazardous materials

Answer: (B)

A combustible gas indicator (CGI) is a device specifically designed to measure the concentration of flammable gases in the atmosphere. It works by detecting various combustible gases and vapors, which is essential for ensuring safety in environments where such gases may be present, such as in hazardous materials incidents or confined spaces. The ability to measure the concentration of these gases helps responders assess the risk of fire or explosion, enabling them to take appropriate action to mitigate hazards. This tool is critical in hazardous materials response, ensuring that first responders can navigate potentially dangerous situations effectively and safely.
