A lifebuoy on a ship is more than just an orange donut. Its characteristics are clearly defined in international documents:
π’ SOLAS (Chapter III) β basic requirements for life-saving appliances.
π’ LSA Code (Chapter II, 2.1) β technical characteristics of lifebuoys.
π’ IMO MSC.81(70), Part 1 β testing procedures.
The main IMO lifebuoy tests are:
- Temperature cycling test β checking operation after sudden temperature changes
- Drop test β can the lifebuoy withstand a drop onto a steel deck?
- Oil resistance test β 24 hours in diesel fuel: should it not lose buoyancy?
- Fire test β 2 seconds in a flame to prevent igniting?
- Flotation test β the lifebuoy with a 14.5 kg iron weight must float for 24 hours?
- Strength test β checking tensile strength/load?
- Light & smoke signal test β how it works with light and smoke?
- Self-activating smoke signal test β testing the signal itself?
βοΈ All these tests are conducted at the type approval stage β that is, when the lifebuoy model is approved. βοΈ On board, the crew conducts periodic inspections (usually every 6 months) and records in the LSA Log/PMS to ensure the lifebuoys maintain their properties.
β οΈ Bottom line: if a lifebuoy fails even a simple on-board inspection (for example, noticeable water absorption), it’s a signal to replace it. SOLAS and the LSA Code require that all lifesaving equipment on board be in working order at all times.
