Personal cooling system for shipboard firefighters

A method of reducing heat stress in at least one firefighter onboard a ship comprising the steps of:

• reducing pressure the of pressurized cooling water received from a shipboard pressurized water source at a first pressure to a second pressure in an in-line flow regulator;
• feeding said pressurized cooling water at said second pressure through a feeder hose connected to said in-line flow regulator;
• conducting said pressurized cooling water at said second pressure from said feeder hose through a tube suit worn by a firefighter;
• and
• transferring heat by said tube suit between said firefighter and said conducted pressurized cooling water at said second pressure.

A system for reducing heat stress in at least one shipboard firefighter comprising:

• means for providing pressurized cooling water at a first pressure onboard a ship;
• means connected to said pressurized cooling water providing means for reducing pressure of said pressurized cooling water at said first pressure to a second pressure;
• means coupled to said pressure reducing means for feeding said pressurized cooling water at said second pressure;
• means connected to said feeding means for conducting said pressurized cooling water at said second pressure over a firefighter to reduce heat stress of said firefighter.
