HAZARDOUS PROPERTY INFORMATION <br /> EXPLANATIONS AND FOOTNOTES <br /> Water solubility is expressed in different terms in different references. Many references use the term <br /> "insoluble"for materials that will not readily mix with water, such as gasoline. However,most of <br /> these materials are water soluble at the part per million or part per billion level. Gasoline, for <br /> example,is insoluble in the gross sense, and will be found as a discrete layer on top of the <br /> groundwater. But certain gasoline constituents, such as benzene, toluene, and xylene will also be <br /> found in solution in the groundwater at the part per million of part per billion level. <br /> a. Water solubility expressed as 0.2 g 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 burn <br /> in presence of high energy ignition source or will form explosive mixtures at temperatures <br /> above 2000F. <br /> d. Practically non-flammable under standard conditions. <br /> e. Expressed as mm Hg under standard conditions. <br /> f. Explosive concentrations of airborne dust can occur in confined areas. <br /> g. Values for Threshold Limit Value-Time Weighted Average (TLV-TWA) are OSHA Permissible <br /> Exposure Limits except where noted in h and I. <br /> h. TLV-TWA adopted by the American Conference of Governmental Industrial Hygienists, which <br /> 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 /> k. Dermal Toxicity data is summarized in the following three categories: <br /> Skin Penetration <br /> A - negligible penetration (solid-polar) <br /> + B - slight penetration(solid-nonpolar) <br /> ++ C - moderate penetration(liquid/solid-nonpolar) <br /> — +++ D - high penetration(gas/liquid-nonpolar) <br /> Systemic Potency <br /> E slight hazard -LD,0 = 500-15,000 mg/kg <br /> lethal dose for 70 kg man = 1 pint-1 quart <br /> G:\WP\GDMGF141017G.356 0•2 <br />
