The stamped full weight of a 100 lb. CO₂ cylinder is 314 pounds. What is the total minimum weight of the cylinder before it must be recharged?

🔍 Key Concepts

• CO₂ fixed fire-extinguishing systems typically allow a 10% loss of charge before requiring recharge • Understand the difference between cylinder tare weight, charge (agent) weight, and full (stamped) weight • You must calculate what minimum acceptable full weight is, given the allowable percentage loss of CO₂

💭 Think About

• What percentage of the CO₂ charge can be lost before the cylinder must be recharged, according to standard practice and regulations? • If the stamped full weight is 314 lbs for a 100 lb charge, what part of that 314 lbs is just the CO₂ and what part is the empty cylinder? • Once you know the allowed loss of CO₂, what new total weight (cylinder plus remaining CO₂) corresponds to that maximum allowed loss?

✅ Before You Answer

• Be sure you correctly separate empty cylinder weight from CO₂ charge weight before doing any percentage calculation • Confirm you are applying the allowable loss to only the CO₂ charge, not to the full cylinder weight • After computing the minimum acceptable weight, check which choice is closest but not greater than your calculated value
