Cylinders should be chained in a vertical position?

• A. True
• B. False
• C. Only when full
• D. Never

Answer: (A)

Gas cylinders must be secured upright to prevent tipping and protect the valve and regulator. When a cylinder is chained in a vertical position, it can’t roll or fall, which avoids valve damage, gas leaks, or a sudden release in a crowded workspace. This safety practice applies whether the cylinder is full or empty, so keeping them vertical and chained is the safest standard. Storing them on their side or not securing them increases the risk of damage and injury, which is why the statement is true.
