What does NOAA recommend?
A basic procedure if one has to dive in high risk water involves reducing the exposure of the diver. NOAA has pioneered a sophisticated SOS (suit over suit) system that will virtually isolate the diver from any contact with the water. This system is somewhat complex inasmuch as it requires complete system integrity from the times the diver dresses out until the system has been decontaminated following the dive. Strict procedures are followed to ensure that the divers body does not contact the fluid in which it is immersed. Previously, many public safety divers wore a single dry suit and a full face mask during their dives. However, Stephen Barsky now states that “Full-face masks only provide minimal protection and should only be used in environments where the pollutants are known, and do not pose a threat of death or permanent disability. In environments where the pollutants are not known, or where they lead to death or permanent disability, a helmet should be worn connected to a matin
