🔍 Key Concepts

• CO₂ extinguisher maintenance standards under 46 CFR (fire protection regulations) • Difference between volume of charge and weight of charge in CO₂ systems • Normal allowable loss of CO₂ charge over time before recharging is required

💭 Think About

• Ask yourself: Which method of checking a CO₂ extinguisher’s condition is most practical and commonly used on board—measuring volume or weighing the cylinder? • Consider what the regulations treat as an acceptable percentage loss over time before a cylinder is considered unserviceable. • Think about the difference between scheduled inspections and the specific condition that actually triggers mandatory recharging.

✅ Before You Answer

• Verify whether regulations talk about weight loss percentage, not just visual level or volume. • Check that you can distinguish between inspection intervals (when you look at it) and service criteria (when it must be recharged). • Confirm what is considered the maximum allowable loss of CO₂ charge before the extinguisher is removed and recharged.
