It is felt, however, that the installation of these facilities encouragescarelessness in the fueling process. When a fueling plant has been properly designed and operated there is a negligibleamount of fuel loss and fire hazards are at the minimum, but since we can expect acci-dents to occur, the design of the plant should include properly engineered fire fires have a small beginning, and to prevent a major catastrophe portable extinguish-ers of the proper type for oil fires should be strategically located and readily accessible. Water, Oil, and Sanitation Services 449. Fig. 5—Concreted roadway with collecting trough sloped to a sump,using stub ties for rail support. A review of the plant layout will suggest where fires are most apt to start, and portableextinguishers should be placed in convenient protected enclosures. They should be simpleand standardized so that it will be unnecessary to instruct each individual employee howto operate them for best results. A permanent fire-fighting facility should be based on the premise that there are onlythree methods of controlling a major oil fire, viz, by blanketing it with foam to stopthe release of the flammable vapor, by rapid cooling with water fog to stop the heatrequired for vaporization, or control by agitation with gas. Fire hydrants should be carefully located so that in case of a major fire they are notin an untenable locality.
