What is the approximate weight range for CO2 cylinders?

• A. About 50 pounds, plus or minus 3 pounds
• B. About 60 pounds
• C. About 40 pounds
• D. About 70 pounds

Answer: (A)

The weight commonly used for a CO2 extinguisher cylinder is about 50 pounds when full, with a small tolerance. That means a full cylinder is typically around 50 pounds, plus or minus about 3 pounds, so roughly 47 to 53 pounds. This range accounts for slight variations in manufacturing and fill density. The other weights are farther from the standard full-cylinder weight, which is why they aren’t used for estimating handling or storage. Remember, as the cylinder empties, it becomes lighter, but the expected full-weight figure is around 50 pounds.
