LIFE BUOY WEIGHT OVER 2.5KGS, MED APPROVED 330159

Use this code for the ordinary positions and order the bridge-wing quick-release buoys separately as IMPA 330160 (over 4 kg, MED). Since MSC.207(81), a lifebuoy that operates the quick-release for smoke signals and lights must weigh not less than 4 kg. A 2.5 kg buoy is not enough for that position.^[2]

Say which buoys get which fittings, because the rules keep lifelines and lights apart. Under US rules at least one lifebuoy on each side carries a buoyant lifeline, at least twice the stowage height or 30 m long, whichever is greater. Buoys with lifelines may not carry self-igniting lights. At least half the buoys carry lights, divided equally between the sides. Order the lifeline length and the lights as separate lines.^[3]

The other 2.5 kg codes differ only in approval: Hong Kong (330151), UK DOT (330156), DNV (330157) and USCG (330158). Order the one the flag accepts, and ask for the ship’s name and port of registry in block capitals on each buoy.^[3]

The LSA Code sets the lifebuoy itself: outer diameter not more than 800 mm, inner diameter not less than 400 mm, inherently buoyant material, support of at least 14.5 kg of iron in fresh water for 24 h, and a mass of not less than 2.5 kg. It must survive a drop from its stowage height or 30 m, whichever is greater, and carry a grabline of at least 9.5 mm diameter, at least four times the buoy’s outside diameter long, secured at four points to form four equal loops.^[1]

A buoyant lifeline must be non-kinking, at least 8 mm in diameter and of at least 5 kN breaking strength.^[1]

Lifebuoys are item MED/1.1 under the Marine Equipment Directive, with standards updated by Implementing Regulation (EU) 2025/1533 from 23 September 2025. Conformity is shown by the wheel mark and a Declaration of Conformity.^[4]
