Solvent supplier was required to furnish clean product with a flash point sufficiently high enough to insure that the spent stream did not exhibit any characteristics of ignitability. The interval between changing the solvent was also increased from 30 to 90 days.
In addition, purchasing personnel stopped buying any product that contained any form of chlorinated hydrocarbon to insure that the washing solvent is not contaminated in this manner.
By changing the solvent to a non hazardous stream, 4,500 to 5,000 lbs. of hazardous waste was eliminated annually.
