“Thermal Protective Aid”的意思、由来-开放百科全书

A Thermal Protective Aid (TPA) is an aluminized polyethylene suit with heat sealed seams that protects from the elements and prevents hypothermia.

It is defined by the International Life-Saving Appliance (LSA) Code^[1] as follows:

A thermal protective aid shall be made of a waterproof material having a thermal conductance of not more than 7,800 W/(m²K) and shall be so constructed that, when used to enclose a person, it shall reduce both the convective and evaporative heat loss from the wearer's body.

1. cover the whole body of persons of all sizes wearing a lifejacket with the exception of the face. Hands shall also be covered unless permanently attached gloves are provided;

2. be capable of being unpacked and easily donned without assistance in a survival craft or rescue boat; and

3. permit the wearer to remove it in the water in not more than 2 min, if it impairs ability to swim.

The thermal protective aid shall function properly throughout an air temperature range -30°C to +20°C.|author=International Convention for the Safety of Life at Sea (SOLAS)}}

Every survival craft should have 2 thermal protective aid suits or 10% of its total carrying capacity whichever is greater.^[2] For the purpose of high visibility in all weather conditions the suit is coloured in international orange.^[3]

Some manufacturers currently construct suits with discrete size bands (XS–XXL) and others of a single ‘universal’ size.^[4] Due to its usage conditions it should be suitable to be worn over bulky clothing and lifejacket.^[5]
