Water-safety products provide equipment for individuals working on, in, or around bodies of water to protect themselves or others. Emergency personnel typically utilize this equipment when reacting to water rescues and floods. Immersion survival and rescue suits keep you dry, protect you from hypothermia, and let you float. In deep or unpredictable waters, life jackets and PFDs keep people afloat. Ring buoys for assisting troubled swimmers and rescue boats for escape sinking or capsized ships are examples of water-rescue equipment.
