330 . <br /> FUEL OIL NO. 2 <br /> Combustible Liquid <br /> TECHNIQUE <br /> FOAM . . :Firefighting foam applied to the surface of liquid pools may slow the release of fuel oil no. 2 <br /> vapors into the atmosphere(where necessary.) <br />' CONSEQUENCE <br /> The effects of foam may be short term. As the foam breaks down, release of vapors will increase. <br /> Products of foam breakdown will add to the volume of spilled material. <br /> MITIGATION <br /> Continue foam applications until spilled product is removed. Contain increased volute <br /> LAND SPILL <br /> TECHMQUE <br /> CONTAINMENT DIKES ... FueI oil no. 2 may be contained by building dikes or barriers using soil, <br /> sand or other materials. <br /> CONSEQUENCE <br /> Contained fuel oil no. 2 may percolate into soil or seep through dike material.This may result <br /> m loss of contained product and spread of contaminat wmL <br /> MITIGATION <br /> Remove contained product as soon as possible to prevent spread ofcontamination. Be alert to <br /> conditions such as fire hose runoff or rainwater that may overfill impoundments. Where <br /> possible, line collection basins with compatible impervious material. <br /> TECHNIQUE <br /> EXCAVATION . .. A:trench or ditch may be e=vated to contain leaking product. <br /> CONSEQUENCE <br /> There may be increased potential for groundwater contamination in some cases. <br /> MITIGATION <br /> Remove contained products as soon as possible to prevent spread of contamination. Use surface <br /> dikes or barriers where groundwater contamination is possible or line collection basin with <br /> compatible impervious material. <br /> TECHNIQUE <br /> PUMPING/VACUUM SUCTION...Accumulated liquid pools may be recovered using appropriate <br /> ham, pumps and gage containers or vacuum trucks. <br /> CONSEQUENCE <br /> Equipment that is incompatible with the spilled product may become damaged or develop leaks. <br />' MITIGATION <br /> Use equipment compatible with spilled product. <br /> TECIMIQUE <br /> ABSORPTION ... Spreading of spilled product may be controlled by absorbing liquid with send,earth, <br /> may, fly ash, cement powder,peat moss,saw dust, straw,commercial sorbenta,or other compatible <br /> substances. <br /> CONSEQUENCE <br /> Once used,sarbent materials pose the acme hazards as the spilled product Their use adds to <br /> the overall volume of contaminated material. <br /> MITIGATION <br /> Deplete accumulated liquid pools with pumps or vacuum trucks if possible before applying <br /> sorbenta. Remove contaminated sorbents to safe storage by mechanical means. <br />
