What are the four types of hypothermia clothing used by the Coast Guard?

The correct answer identifies the four types of hypothermia clothing used by the Coast Guard: wet suits, dry suits, insulated overalls, and thermal layers. Each of these clothing types plays a crucial role in preventing heat loss in cold water or inclement weather conditions.

Wet suits are designed to keep the body warm by allowing a thin layer of water to enter, which is then warmed by the body heat. They are primarily used in aquatic environments.

Dry suits, on the other hand, provide a waterproof barrier that keeps water away from the body entirely. This suit does not allow water in, which is particularly valuable in extremely cold conditions, ensuring that the wearer remains dry and warm.

Insulated overalls provide additional warmth and insulation, typically used in combination with other clothing to protect against extreme cold.

Thermal layers are crucial for maintaining body heat. These include specially designed fabrics that trap heat close to the body, preventing it from escaping. Each of these clothing types is essential for protecting Coast Guard personnel from the dangers of hypothermia while on duty, especially during search and rescue missions or operations in cold water environments.
