| Portable extinguishers — annual inspection and servicing | Annual | SOLAS II-2 Reg. 14.2.2, to the guidelines for marine portable fire extinguishers in IMO Res.

|---|
| Portable extinguisher bodies — hydraulic pressure test | 10-yearly | SOLAS II-2 Reg. 14.2.2, to IMO Res. A.951(23) §9.1.2 — all extinguisher bodies together with propellant cartridges hydraulically tested to the recognized standard or the maker's instruction at intervals not exceeding ten years | cylinders that fail the test are withdrawn and replaced |
|---|
| Spare charges for portable extinguishers | Carried on board | SOLAS II-2 Reg. 10.3.3 | 100% of the first ten, 50% of the remainder capable of recharge on board; sixty required at most |
|---|
| Fixed CO₂ cylinders — hydrostatic test | 10-yearly | SOLAS II-2 Reg. 14.2.2, to the guidelines in MSC.1/Circ.1318/Rev.1, which supersedes MSC.1/Circ.1318 and is the instrument MSC.1/Circ.1432 §1 refers to for fixed carbon dioxide systems | at each ten-year inspection 10% of the agent and pilot cylinders are internally examined and hydrostatically tested — 50%, then all, if any fail; before the 20-year anniversary and every ten years thereafter all cylinders are tested |
|---|
| Fire hoses and nozzles — pressure test | Annual sample; every hose within 5 years | SOLAS II-2 Reg. 14.2.2, to the guidelines in MSC.1/Circ.1432 §7.1.4 as amended by MSC.1/Circ.1516 | a sample is pressure tested each year at maximum fire main pressure, chosen so that every hose is tested within five years; hoses that fail are withdrawn from service and replaced |
|---|
| Fixed foam concentrate — replacement after analysis | On failed analysis | SOLAS II-2 Reg. 14.2.2, to the guidelines in MSC.1/Circ.1432 as amended by MSC.1/Circ.1516 — periodical foam concentrate analysis | sample drawn on the attendance; concentrate replaced where it fails |
|---|
| SCBA spare air charges | Carried on board | SOLAS II-2 Reg. 10.10 | two per required set; one only where cylinders recharge on board — not on ships carrying over 36 passengers |
|---|
| Inflatable liferafts and inflatable lifejackets — servicing at an approved station | ≤12 months | SOLAS III/20.8 | equipment pack, gas cylinder and firing head renewed; extendable to 17 months where servicing at 12 months is impracticable and the Administration so permits |
|---|
| Disposable hydrostatic release units — renewal | At marked expiry | Manufacturer's marked expiry date — no IMO instrument sets this interval | non-disposable units are serviced at ≤12 months under SOLAS III/20.9 |
|---|
| Launching falls — periodic inspection and renewal | 5-yearly | SOLAS III/20.4 as amended by IMO Res. MSC.404(96), in force 1 January 2020 | inspected periodically with special regard to areas passing through sheaves; renewed on deterioration or at five years |

|---|
| Pyrotechnic distress signals — renewal | At marked expiry | Manufacturer's marked date of expiry; the LSA Code requires the expiry date to be marked and sets the performance standard, but does not fix the service life | expired signals landed for disposal, never retained on board |
|---|
| Lifting appliances and loose gear — examination and load test | Annual, with 5-yearly load test | ILO Convention No. 152 and its Code of Practice; examination required under SOLAS II-1/3-13, in force 1 January 2026 | wire rope renewed to ISO 4309 discard criteria; every replacement entered in the register |
