🔍 Key Concepts

• Annual CO2 cylinder inspection looks for loss of charge by weight • Net CO2 charge = gross weight − tare weight for each cylinder • A cylinder must be recharged if the loss in CO2 weight exceeds 10% of its full charge

💭 Think About

• First, compute the CO2 content in pounds for each cylinder in the table; which ones are clearly lower than the rest? • Assume a normal full charge based on the best-filled cylinders in the list; what does 10% of that value look like? • Compare each cylinder’s CO2 content to that minimum acceptable value; which cylinders fall below it?

✅ Before You Answer

• Be sure you subtract tare from gross (not the other way around). • Use the same ‘full-charge’ reference for all cylinders when applying the 10% rule. • Confirm that any cylinder you select is more than 10% below the normal charge, not just slightly below.
