🔍 Key Concepts

• Small passenger vessel fire protection requirements in 46 CFR Subchapter T • Required inspection procedures for fixed and portable CO2 extinguishers at an inspection for certification • Difference between weight checks, pressure checks, and hydrostatic tests

💭 Think About

• Think about what test or check is practical to perform on every CO2 extinguisher during each inspection, without taking all equipment out of service for long periods • Consider which procedures are normally done on a periodic schedule (e.g., every several years) versus those done every inspection • Ask yourself which method best confirms that a CO2 extinguisher still contains the proper amount of agent, given that CO2 extinguishers usually do not have a conventional pressure gauge

✅ Before You Answer

• Verify in 46 CFR Part 176 – Inspection and Certification and associated fire protection sections what is required at each inspection for certification • Check which maintenance items (like hydrostatic testing) have multi‑year intervals and would not be required at every inspection • Confirm how CO2 charge condition is normally determined: by weight, by pressure, or by discharging the unit
