What is an explosimeter?

• A. A device that measures humidity inside a tank
• B. A device that measures tank pressure
• C. A device that measures temperature inside a tank
• D. A device that measures how explosive or toxic the atmosphere is inside the petroleum tank

Answer: (D)

An explosimeter is a safety instrument used to check the atmosphere inside a tank for hazards before entry, specifically to detect explosive or toxic gases. This makes it the right choice because it directly describes measuring how explosive or toxic the atmosphere is inside the petroleum tank. Humidity, tank pressure, and temperature are different environmental properties and do not assess flammability or toxicity, so they don’t describe the purpose of an explosimeter.
