Water delivered as a spray is more effective against hydrocarbon fires than a stream of water. Water as a mist is even more effective. The delivery system influences the effectiveness of water. The major problem with using water in a combat vehicle is freezing at low temperatures. Additives can be added to lower the freezing point Thus, water solutions may be usable under all expected operating conditions. Experiments have been conducted using sprays of water and water with additives to extinguish JP-8 pool fires. Additives were chosen to provide low freezing points to the water and to improve the fire extinguishing capability of the water. As expected, sprays of just water were not particularly effective for extinguishing JP-8 pool fires. Water with calcium chloride, added to give a -55 deg C freezing point, showed no improvement in fire suppression over the baseline water tests. Other additives, however, showed remarkable improvements over the water case.
