HAZARDOUS PROPERTY INFORMATION <br /> EXPLANATIONS AND FOOTNOTES <br /> Water solubility is expressed in different terms in differ I ent references. Many references <br /> use the term *insoluble" for materials that will not readily mix with Water, such as gasoline. <br /> However, most of these materials are water soluble it the part per million or part per billion <br /> level. Gasoline, for example, is insoluble in the gross sense, =4 will!"be round as a discreet <br /> layer on top of the ground water. But certain gasoline.constituents, such as benzene, toluene, <br /> and xylene will also be round in solution in the ground water at the part per million: of part per <br /> billion level. <br /> a. Water solubility expressed as 0.4 means 0.2 grams per 100 grams water at 200C. <br /> b. Solubility of metals depends on the compound in which they are present. <br /> C. Several chlorinated hydrocarbons exhibit no flash point in conventional sense, but will <br /> burn in presence of high energy ignition source or will f6rm explosive mixtures at <br /> tt temperatures above 2000F. <br /> d. Practically non-flammable under standard conditions. <br /> e. Expressed as mm H& under standard conditions_ <br /> f. <br /> Explosive concentrations of airborne dust can occur in confined areas. <br /> S. Values for Threshold Limit Value-Time Weighted Average (TLV-TWA) are-OSHA <br /> Permissible Exposure Limits except where noted in h and L <br /> h- TLV-TWA adopted by the American Conference-of Governmental Industrial.Hygienists, <br /> which is lower than the OSHA PEL. <br /> i, TLV-TWA recommended by the national institute for Occupational Safety and Health <br /> (NIOSH). A TLV or PEL has not been adopted by ACGIH or OSHA. <br /> j. A - corrosive <br /> B - flammable <br /> C - toxic <br /> D - volatile <br /> E - reactive <br /> F - radioactive <br /> G - carcinogen <br /> H - infectious <br /> A3014-CP <br /> July 1,1M <br /> 7 <br />
