Safety, Fire & Survival · Survival — Thermal Protective Aid
How does a thermal protective aid (TPA) carried in survival craft help a casualty?
- AIt provides buoyancy in the water like a lifejacket
- BIt is a waterproof, low-conductivity bag/suit that reduces convective and evaporative body-heat loss in the survival craft✓ Correct
- CIt signals rescue aircraft
- DIt purifies seawater for drinking
Explanation
A TPA is a bag or suit of waterproof material with low thermal conductance that covers all but the face, cutting convective and evaporative heat loss for a survivor in a lifeboat or raft. It is not a flotation device and is intended for use out of the water after recovery.
