Water-safety products provide equipment for people to protect themselves or assist others who are working on, in, or near bodies of water. This equipment is commonly used by emergency teams responding to water rescues and floods. Immersion survival and rescue suits block out water, protect against hypothermia, and aid flotation. Life jackets and PFDs keep people afloat in deep or unpredictable waters. Water-rescue equipment includes ring buoys for helping distressed swimmers and rescue boats for escaping sinking or capsized ships.
