Carbon dioxide cylinders must be recharged when the weight of the charge has diminished to what percent?

Question 1 of 27070

Carbon dioxide cylinders must be recharged when the weight of the charge has diminished to what percent?

🔍 Key Concepts

• Fixed CO₂ fire-extinguishing systems inspection requirements in 46 CFR • Allowable loss of extinguishing agent before recharging is required • Difference between full charge and the minimum acceptable percentage of charge

💭 Think About

• Think about how much weight loss (as a percentage of the original charge) is typically allowed before the system is considered unsafe or ineffective. • Which of these percentages would represent a reasonable safety margin so the system still works properly, but does not require constant recharging? • Compare these values to the idea of a 10% loss vs. a 5% loss of extinguishing agent — which one matches standard inspection limits for CO₂ cylinders?

✅ Before You Answer

• Verify in 46 CFR that CO₂ cylinders must be recharged when the loss in weight exceeds a certain percentage of the charge. • Confirm whether the regulation speaks in terms of maximum percentage loss allowed (e.g., 10%) or minimum percentage of charge remaining (e.g., 90%). • Make sure the option you choose matches the idea: recharge when weight has diminished to X% of the original charge, not when it is still nearly full.
