SDS . EXPLANATIONS AND FOOTNOTES: a Water solubility is expressed in different terms in different references. Many references use the term"insoluble"for materials that will not readily mix with water, such as gasoline. However, most of these materials are water soluble at the part per million or part per billion level. Gasoline,for example, is insoluble in the gross sense, and will be found as a discrete layer on top of the ground water. But certain gasoline constituents, such as benzene,toluene, and xylene,will also be found in solution in the ground water at the part per million or part per billion levels. b Solubility of metals depends on the compound in which they are present. Several chlorinated hydrocarbons exhibit no flash point in a conventional sense, but will burn in the presence of high energy ignition source or will form explosive mixtures at temperatures above 200 ❑F. d Expressed as mm Hg under standard conditions. e Explosive concentrations of airborne dust can occur in confined areas. Cal/OSHA Time-weighted Average(TWA) Permissible Exposure Limits(PELs)except where noted in g.The substances designated by"Skin" in the PEL column may be absorbed into the bloodstream through the skin,the mucous membranes and/or the eye, and contribute to the overall exposure."C"notation indicates the number given is a ceiling value. 9 TLV-TWA adopted by the American Conference of Governmental Industrial Hygienists(ACGIH). Currently,there is no Cal/OSHA PEL. h The substances with a"Ca" notation in the IDLH column are considered to be potential occupational carcinogens by NIOSH. Odor thresholds values extracted from"ODOR THRESHOLDS for Chemicals with established Occupational Health Standards",American Industrial Hygiene Association, 1997. (d) Odor detection threshold: Lowest concentration at which a stimulus is being detected. (r) Odor recognition threshold: Lowest concentration at which a definite odor character is detected.
