Which statement about cylinder safety on the job site is true?

• A. Cylinders should be placed near welding operations.
• B. Cylinders should be stored away from heat sources.
• C. Cylinders should be kept in direct sunlight.
• D. Cylinders can be left on the job site when you leave.

Answer: (B)

Storing cylinders away from heat sources is essential because heat increases the pressure inside a compressed gas cylinder. When a cylinder gets hot, the gas inside expands and the internal pressure rises; in a worst-case scenario, this can lead to a cylinder venting, leaking, or even a rupture, especially if the cylinder is damaged or near ignition sources. Keeping cylinders cool and out of direct heat or sun minimizes that risk and helps preserve valve integrity and overall safety on the job site. Placing cylinders near welding operations exposes them to sparks, flames, and radiant heat, which can ignite leaking gas or damage the cylinder, so that choice is unsafe. Leaving cylinders on the job site when you leave creates a risk of leaks, tampering, or being knocked over, which is also unsafe. Storing in direct sunlight subjects the cylinder to heat as well, so that option is not consistent with safe practice.
