An explosimeter measures the atmospheric conditions inside which location?

An explosimeter measures the atmospheric conditions inside which location?

• A. A laboratory fume hood
• B. A storage closet
• C. The petroleum tank
• D. Inside a building's storage tank environment

Answer: (C)

Explosimeters are used to assess whether the air in a space is capable of supporting an explosion by measuring flammable vapor concentration and other atmospheric conditions. The petroleum tank is a classic location where flammable vapors from the liquid can accumulate in a confined space, creating an explosive atmosphere. Before entering such a space, you’d check the air to ensure safety. A lab fume hood is designed to vent fumes and isn’t the typical environment where you assess explosivity, and a storage closet or a building’s storage tank environment could also have vapors, but the petroleum tank represents the standard scenario where monitoring the atmosphere with an explosimeter is essential.
