In firefighting, fires are identified according to one or more fire classes. Each class designates the fuel involved in the fire, and thus the most appropriate extinguishing agent. The classifications allow selection of extinguishing agents along lines of effectiveness at putting the type of fire out, as well as avoiding unwanted side-effects. For example, non-conductive extinguishing agents are rated for electrical fires, so to avoid electrocuting the firefighter.
Multiple classification systems exist, with different designations for the various classes of fire. The United States uses the NFPA system. Europe use the European Standard "Classification of fires" (EN 2:1992, incorporating amendment A1:2004). Australasia uses yet another.

Famous quotes containing the words fire and/or classes:
“Bare night is best. Bare earth is best. Bare, bare,
Except for our own houses, huddled low
Beneath the arches and their spangled air,
Beneath the rhapsodies of fire and fire,
Where the voice that is in us makes a true response....”
—Wallace Stevens (1879–1955)
“Classes struggle, some classes triumph, others are eliminated. Such is history; such is the history of civilization for thousands of years.”
—Mao Zedong (1893–1976)
