First "tentatively adopted as a guide" in ,  and revised several times since then, it defines the colloquial " Safety Square " or " Fire Diamond " used by emergency personnel to quickly and easily identify the risks posed by hazardous materials. This helps determine what, if any, special equipment should be used, procedures followed, or precautions taken during the initial stages of an emergency response. The four divisions are typically color-coded with red on top indicating flammability , blue on the left indicating level of health hazard, yellow on the right for chemical reactivity , and white containing codes for special hazards.

Flammable and combustible liquid fires are much more volatile than fires fueled by ordinary combustibles, such as wood, paper, and cloth. Flammable vapors ignite with explosive force, and the resulting fire gives off more than twice as much heat as ordinary combustibles. The rate of temperature rise is greater, and burning liquids produce billowing clouds of thick, toxic, black, and acrid smoke. Flammable liquid fires also spread rapidly when spilled material flows into low lying areas, sometimes many feet away from the original spill. Because of these hazards, special precautions are required when storing, handling, and using flammable liquids. The flash point of a liquid is defined as the minimum temperature at which a liquid gives off sufficient vapor to ignite in the presence of a source of ignition. Remember, it is the vapor that burns and not the liquid.
