Materials

Kapok:

Kapok, often used to manufacture life jackets and cushions, is contained in vinyl coverings which are easily punctured.  Kapok deteriorates quickly and loses its buoyancy.  Kapok can support 25 times its weight.

Single-cell foam:

Polyethylene and airex are two very common types of foam.  Foam is a very long-lasting buoyant material.

Maintenance

Regularly check that life jackets or PFD's are still properly buoyant. The foam should not be too rigid. Kapok sacks must be light, soft to the touch and puncture-free.

Life jackets and PFD's should be worn on board.  They should not be used for kneeling, sitting or as a fender.

When wet, rinse flotation gear in fresh water and hang to dry in the open air or a well-ventilated location.  Do not expose them to direct heat.

Store life jackets and PFD's in a cool, well-ventilated area.

Clean with mild soap and water. Strong detergents, dry cleaning and petroleum products can damage flotation gear.
