^` I. HAZARDOUS PROPERTY INFORMATION <br /> Explanations and footnotes <br /> Water solubility is expressed in different terms in different 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 at the part per millon or part per <br /> billion level. Gasoline for example, is insoluble in the gross sense, and will be found as <br /> a discreet layer on top of the groundwater. But certain gasoline constituents, such as <br /> benzene,toluene, and xylene will also be found in solution in the groundwater at the part <br /> per millon or part per Million level. <br /> A. Water solubility expressed as 0.2g means 0.2 grams per 100 grams water at 20°C. <br /> B. Solubility of metals depends on the compound in which they are present. <br /> C. Several chlorinated hydrocarbons exhibit no flash paint in conventional sense, but <br /> will burn in presence of high energy ignition source or will form explosive mixtures <br /> at temperatures above 200°F. <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 <br /> Permissible Exposure Umits (PEL) except where noted in H. and I. <br /> H. TLV - TWA adopted by the American Conference of Government Industrial <br /> Hygienists (.ACGIH)which is lower than the OSHA PEL. <br /> I. TLV - TWA recommended by the National Institute for Occupational Safety and <br /> Health (NIOSH). A TLV or PEL has not been adopted by the 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 /> ti. mom <br />
