(Source: Amended at'3 111. Reg. 124. effective July 28. 1979) Section 215.182 Cold Cleaning a) Operating Procedures: No person shall operate a cold cleaning degreaser unless: 1) Waste solvent is stored In covered containers only and not' disposed of In such a manner that more than 2OX of the waste solvent (by weight) is allowed to evaporate Into the atmosphere; 2) The cover of the degreaser is closed when parts are not being handled; and 3) Parts are drained until dripping ceases. b) Equipment Requirements: No person shall operate a cold cleaning degreaser unless: 1) The degreaser'Is equipped with'a cover which is closed whenever parts are not being handled In the cleaner. The cover shall be designed to be easily operated with one hand or with the mechanical assistance of springs, counter-weights or a powered system if: A) The solvent vapor pressure Is greater than 2 kPa (IS mdg or 0.3 psl) measured at'38*C (100*F); 8) The solvent Is agitated: or C) The'solvent ;1s heated above ambient room temperature. . . 2) The degreaser-is equipped with a facility . for draining cleaned.parts. The drainage facility shall be constructed so that parts-are-enclosed under the cover while draining unless:" 1 A) The Solvent vapor pressure Is less . than 4.3 kF (32 anffg or 0.6 psl) measured-et 38*t(10QF); or-- B) An' Internal .drainage facility cannot be fitted into the cleaning system. v In wtfrcfr case the drafnage raclTIty jmay be external. 3.)
