Every Lifebuoy should,

> have an outer diameter of not more than 800 mm and an inner diameter of not less than

400 mm

> Constructed by an inherently buoyant material

> Support 14.5 kg of iron in fresh water for a period of 24 Hours

> have a mass of not less than 2.5 kg

> resist the fire upto 2 second

> Able to sustain a drop of 30m or the height of stowage, whichever is greater

> be filled with a grabline not less than 9.5 mm in diameter and not less than 4 times the

outside diameter of the body of the buoy in length.

>  The grabline shall be secured at four equidistant points around the circumference of the buoy to form four equal loops

> At least 50% lifebuoys fitted with self igniting lights

> 2 buoys with lights to have smoke and be able to be released from the bridge.

> all types to be evenly distributed on both sides

> Minimum No.--
