Mist fire pumps provide what duration of fresh water and at a flow rate of?

• A. 10 min; 180 GPM
• B. 12 min; 200 GPM
• C. 20 min; 240 GPM
• D. 15 min; 230 GPM

Answer: (D)

Mist firefighting uses a fine water spray drawn from the ship’s potable water system to absorb heat and smother flames. The pump for this system is rated to deliver a steady 230 gallons per minute, and it can run for about 15 minutes before the potable water supply is exhausted. This combination—230 GPM for 15 minutes—provides enough mist output to control and suppress fires while other firefighting actions are coordinated and additional water sources are brought online.
