WebFlammable liquids must be handled in a fume hood, unless it is known that the permissible exposure limit (PEL) and lower explosion limit (LEL) will not be exceeded. The LEL is defined as the minimum concentration of a particular flammable or combustible vapor necessary to support combustion in air. Web(NFPA, 2010) General Description A clear colorless to amber colored, volatile liquid with a petroleum-like odor. Flash point below 0°F. Less dense than water and insoluble in water. Hence floats on water. Vapors heavier than air. Leaked vapors may travel to a source of ignition and then flash back to the source. Hazards What is this information?
