Shot in Los Angeles with the cooperation of the LAFD, it dates to 1962. The film opens with scenes of firemen working to put out a fire on a rooftop (:07) as well as fire ambulances running down a main drag in a city area (:10). Main titles (:37). A firefighter uses a hose to put out a burning building (:44). Large smoke clouds are seen in the background as two firemen prepare to fight the flames (:56). The film shows the various methods of how fires are put out (1:04) by a large city fire department. (The station shown at 1:30 is Station 30, which now houses the Los Angeles Fire Department Museum) Within the fire department laboratory technicians learn the principles of fire control (1:17). The three factors which contribute to a fire starting are pointed to as a combustible object; or a fuel (1:29), heat (1:36) and gas (1:52). A glass cylinder is set over the burning ball of paper to show how a lack of oxygen puts out the fire (1:58). When these three ingredients are set together; this is what the film refers to as the ‘fire triangle’ (2:23). Various types of fuels are pointed out (2:37). Various fuels are heated with an electric coil or bunsen burner (2:59). An instrument is pointed to which will dictate the temperature of the coil (3:06). As the temperature of the oil rises over 900 degrees; it begins to burn (4:02). The film turns to show a scene of a burning building (4:49). In order to put out a fire, the fire fighters must remove one of the three elements contributing to the fire (5:16). The film asks what must be done in order to fight a forest or brush fire, also known as a wildfire (5:19). In this instance, the fuel can be removed as men hack away at dry timber and shrubs (5:24) which are in the path of the fire. A bulldozer is introduced to the effort to clear away the brush (6:00). In another scene of a fire moving through a small town, the firemen work to remove the heat (6:06) with water hoses. Aerial footage from the roof show firefighters working to put out the flames as another fire truck pulls up to assist (6:28). The third method for controlling a fire is to remove the oxygen (6:53). A fire extinguisher is zoomed in on to show the main ingredient of carbon dioxide (7:06). At a laboratory, the extinguisher is tested to show how it works (7:18). Carbon dioxide; which is heavier than air is poured from a beaker over a flame (7:34). The flames are put out (7:41). Oxygen removal is helpful in oil or gasoline fires as well (8:14). When the fire fighter tries to put out the flame with water it only adds to the flame (8:19). Airport firemen roll up to a B-47 bomber plane, which has been set on fire as part of a drill (8:55) spraying a chemical foam (9:03). The foam smothers the fire (9:12). An electrical fire also requires special techniques to put out (9:57). A demonstration follows showing why the use of water on an electrical fire is dangerous (10:19). The water still acts as a conductor (10:29). A fireman is shown shutting off the electricity in a building which is the first step in fighting electrical fires (10:43). A chemical is sprayed in order to remove the oxygen (10:54). The film wraps up as it goes over the three elements which are used to fight fire (11:41).
