• A. Gas detectors
• B. Combustion gas indicators
• C. Combustible gas indicators
• D. Gas monitors for flammables

Answer: (C)

CGIs are devices that help you assess whether vapors in air can ignite. In hazmat training, they are called Combustible Gas Indicators. The term emphasizes that the instrument is specifically for detecting combustible gases or vapors and indicating their concentration relative to the lower explosive limit, so you can judge if an area is safe to enter or if you need ventilation and precautions. Other phrasings like “gas detectors” or “gas monitors for flammables” are general descriptions, and “combustion gas indicators” would imply measuring combustion products rather than detecting flammable vapors in the atmosphere.
