Cylinders should never be placed near active welding processes, heated processes, or other processes that could possibly throw sparks or slag.

• A. True
• B. False
• C. Only When Supervised
• D. Only With Protective Shields

Answer: (A)

Cylinders must be kept away from welding and any heat, flame, or spark-generating activity because they are pressurized vessels that can fail or ignite if exposed to heat or ignition sources. Heat raises the pressure inside a cylinder and can weaken valves or the vessel itself; acetylene is particularly sensitive to high temperatures, and oxygen can dramatically accelerate combustion if a leak occurs. A spark or slag striking a cylinder valve can cause a dangerous release or rupture, creating a serious fire or explosion risk. For these reasons, store and handle cylinders in a well-ventilated area, upright and secured, away from ignition sources, with caps in place when not in use.
