Abstract:

Most of the water used in firefighting is not only wasted, it also contributes extensively to total damage. Water is an unusual chemical in that, due to hydrogen bonding, it is a liquid at room temperature and it also has a very high heat of evaporation. So, if one could make water adhere significantly to vertical and overhead surfaces, a great deal of fire protection could be bought because such surfaces could not get hotter than the boiling point of water 100 deg C and a great deal of heat energy would be required to evaporate it. This can be accomplished by making water glutinous, either by making a foam e.g., shaving cream or by thickening it e.g. gravy, or both. Calculations and experiment show that up to at least 10 times greater fire protection could be achieved with only about 120 - 150 the amount of water.
