How often must fixed CO₂ fire extinguishing systems be inspected to confirm the cylinders are within 10% of the stamped full charge weight?

🔍 Key Concepts

• Fixed CO₂ fire extinguishing systems maintenance requirements • Inspection intervals specified in 46 CFR and SOLAS Chapter II-2 for CO₂ cylinders • What "within 10% of the stamped full charge weight" is checking (loss of agent vs. general system inspection)

💭 Think About

• Ask yourself: Is the check of cylinder weight a frequent routine check, or a less frequent special test? • Consider the difference between visual/operational inspections and weighing or otherwise verifying the actual CO₂ charge in each cylinder. • Think about how often cylinders could realistically be removed, weighed, or otherwise tested without disrupting vessel operations.

✅ Before You Answer

• Verify in 46 CFR Part 147 or SOLAS II-2 the specific interval for weighing or otherwise confirming CO₂ cylinder contents. • Distinguish between the interval for system inspections and the interval for agent quantity verification (within 10% of full charge). • Confirm that the option you choose matches the regulation phrase about "loss of more than 10%" or similar wording in the CO₂ maintenance section.
