Immersion suits are specialized protective gear designed to provide thermal insulation and buoyancy in cold water, increasing survival chances in maritime emergencies. Made from waterproof and insulating materials, immersion suits help prevent hypothermia by reducing heat loss in freezing conditions. These suits are commonly used on ships, offshore platforms, and rescue operations to ensure crew safety in case of vessel abandonment. Regular inspection, proper fit, and correct usage of immersion suits are essential for maximizing their effectiveness in life-threatening situations.
