The net weight of a CO2 cylinder is within which range?

• A. 50 ± 3 pounds
• B. 60 ± 2 pounds
• C. 45 ± 5 pounds
• D. 52 ± 4 pounds

Answer: (A)

Net weight refers to the amount of CO2 inside the cylinder, excluding the container itself. For this CO2 cylinder, the standard net weight is 50 pounds, with a small tolerance to account for manufacturing variation. The range that fits this spec is 50 ± 3 pounds, which is 47 to 53 pounds. This tight tolerance helps ensure consistent discharge performance and manageable handling on the job. The other options imply too much or too little content or use a broader tolerance that isn’t standard, so they don’t align with the typical net weight specification.
