Which equipment requires stripping, cleaning, and overhaul at least once every two years?

• A. Lifeboat limit switches, winches, and falls
• B. EPIRB devices
• C. Lifeboats, rescue boats, and rigid-type liferafts
• D. Fire extinguishers

Answer: (C)

Focusing on periodic, thorough maintenance of life-saving appliances that are exposed to harsh sea conditions helps you understand why this specific group is singled out. Lifeboats, rescue boats, and rigid-type liferafts undergo a complete overhaul at least every two years. This means they are stripped down, cleaned, inspected in detail, and rebuilt where needed — including the launching gear, falls, release mechanisms, davits, and associated fittings, plus the raft canister, buoyancy components, painter lines, and sea anchor for rigid liferafts. The goal is to uncover hidden wear, corrosion, or deterioration that routine checks might miss and to verify that the entire system will perform reliably when called upon. EPIRBs and fire extinguishers have maintenance needs too, but on different schedules and scopes. EPIRBs are serviced and battery conditions checked regularly, with replacements aligned to battery life and regulatory requirements, rather than a full two-year overhaul. Fire extinguishers are inspected and recharged on shorter cycles, with hydrostatic tests required at specific intervals depending on the type, not a comprehensive stripping and overhaul like the life-saving appliances mentioned above. So, the equipment that requires stripping, cleaning, and overhaul at least once every two years is lifeboats, rescue boats, and rigid-type liferafts.
