PRE-TANK REPLACEMEmr Site Assessment Work Plan 420 WEST KETTLERAN LANE,L00i, CA. Aegis Project No. 89.013 Page 28 G. HAZARDOUS PROPERTY INFORMTION Explanations and footnotes 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 of these materials are water soluble at the gasoline. However, most rt er_._ per billion level. Gasoline for example, is insolubleminitheor part sense, and will be found as a discreet layer on top of the gross water. But certain gasoline constituents, such as benzene, ground and xylene will also be found in solution suthe part per millon or part per billion level. in ground water at the A. Water solubility expressed as 0,2 3 grams water at 20°C. g means 4.2 grams per 100 e. Solubility of metals depends on the compound in which they are rrt present. _ 1 � t C. 'Several chlorinated hydrocarbons exhibit no flash point in conventional sense, but will burn in presence of high energy ignition source or will form explosive mixtures at temperatures above 200*F. # D. Practically non-flammable under standard conditions. E. Expressed as mm Hg under standard co nditions • Explosive co ncentrations of. airborne dust can .occur in confined areas. G. Values for Threshold Limit Value Time Weighted Average (TLV-TWA) are OSHA Permissible Exposure Limits (PLL). except where noted in H. and I. H. TLV -.
