Hose Control Devices

Hose control devices are used aboard aircraft carriers and amphibious aviation ships (LHA's and LHD's) to direct AFFF and/or water to cool down any exposed and at-risk explosives during and after a fire on the flight deck, and possibly the hangar deck, while exposing a minimum number of personnel to a cook-off hazard. After the device is clipped to an aircraft tie-down, hose and nozzle connected, agent on, and stream aimed at the target, the crew can move farther away from the potential explosion hazard. In windy conditions however, one person must stay with the device to adjust the aim of the stream to compensate for the winds blowing the stream off the target.

The ship's allowance of hose control devices are provided free of charge by NAVSEA. The 1 1/2-inch hose control device is under stock number 2S 4210-LL-HAL-4948. The 2 1/2-inch hose control device is available under stock number 2S 4210-LL-HAL-4949.
