An immersion suit and an anti-exposure suit are both designed to keep a person safe and protected in cold water environments. However, there are some key differences between the two.
An immersion suit is designed to provide full-body protection from hypothermia in case of a sudden immersion in cold water. The suit is made of a waterproof material that keeps water out and traps body heat inside. The suit is usually rigidly constructed with thick neoprene or closed cell foam and features built-in gloves, boots, and a hood to seal out water. Immersion suits are commonly used on ships and offshore facilities that must comply with safety regulations, such as the SOLAS requirements.
On the other hand, an anti-exposure suit is designed to keep a person dry and protected from wind, rain, and spray while working in a cold or wet environment. The suit offers some insulation and buoyancy, but it is not as rigid and thick as an immersion suit. Anti-exposure suits are often made of breathable materials such as nylon, polyester, or Gore-Tex and feature adjustable cuffs, collars, and waistbands to customize the fit. These suits are mainly used by commercial fishermen, marine construction workers, and other outdoor professionals who work in cold, wet conditions.
Both immersion suits and anti-exposure suits serve a vital purpose in protecting workers and sea travelers from the dangers of cold water. While they differ in design and function, both types of suits provide necessary protection against hypothermia and other cold water risks.
