🔍 Key Concepts

• CO2 fire extinguisher charging requirements under 46 CFR (see fire protection regulations) • Difference between volume and weight when checking contents of a CO2 extinguisher • How inspectors and crews practically verify that a CO2 extinguisher is adequately charged

💭 Think About

• Ask yourself: In real shipboard practice, what is the easiest, most reliable way to tell if a CO2 extinguisher is low on charge? • Consider whether CO2 in a portable extinguisher is normally measured by how much space it fills or by how heavy the cylinder is. • Think about whether the rule is triggered by a specific percentage below required contents and whether that is tied to volume or weight.

✅ Before You Answer

• Verify whether portable CO2 extinguishers are normally marked with required charge weight (in pounds or kilograms). • Check which is more practical to measure during an inspection: remaining charge weight vs. remaining volume. • Confirm that the regulation speaks in terms of a percentage below required charge and note whether that applies to weight or volume.
