At what temperature should no part of a compressed gas cylinder be exposed to?

A compressed gas cylinder should not be exposed to temperatures above 125°F, as excessive heat can cause increased pressure within the cylinder, leading to the risk of an explosion or rupture. The correct choice indicates a conservative temperature of 85°F, which is well below the critical threshold where safety becomes a concern.

Maintaining the temperature below this level helps prevent the potential for pressure build-up and ensures safe handling and storage of gases. This is crucial for safety protocols in environments where compressed gases are used, as it contributes to minimizing the risk of accidents and injuries associated with gas cylinder failures.
