To prevent <br />contamination of :se parts washer by listed* solvents, db not <br />spray listed aerorris over the unit <br />Change vehicle <br />fluids (oil.'bcake <br />fluid, antifreeze* <br />etc.) - <br />These diemtcals ciut compound <br />waste management problem's by <br />contaminating water and <br />sludge with hazardous materials. <br />Use drip pans imier vehicle to collect fluids. <br />Recyxie transmission arid brake fluids with used oil.' . v <br />Drain radiators be.*bte Cushing and recycle waste antifreeze. <br />Clean shop floors Hosing down the floors with <br />water or solvent can flush <br />contaminants into floor drains, <br />contaminating liquids and <br />sludges in the drain sy stem. <br />Use drip pans to ccllect fluids. Use dry sweeping compounds. <br />Reuse them as Icr.z as they remain absorbent. Combustible <br />sweeping compc.r.ds tray be burned to heat your shop if <br />burned in an apprrved burning device. <br />\ccidentally spill <br />material <br />Many materials used in vehicle <br />maintenance may be hazardous <br />and can contaminate other <br />wastes in the plumbing system. <br />Clean up spills izimediately.

Store solvents in a <br />“flammablcs*’ cabirct. Do not use solvents near drains. <br />Store waste vehicle <br />fluids in a room . <br />with a floor drain <br />Spilled or leaked solvents arid <br />their vapors are dmigerous and <br />can contaminate other wastes in <br />the plumbing system <br />Keep containers sealed when not in use. Keep waste <br />containers in a separate storage area with no floor draim . <br />Install a curb or benn to contain any wastes that may leak from <br />storage containers. Inspect containers for leaks on a we^ly <br />basis See htPCA Hazardous Waste fact sheet #2.41, <br />Documeniing Cor.:ainer Inactions. <br />Wash engines The resulting wastewater is <br />likely to be hazardous from <br />greases, oils and solvents. <br />Only wash engines if absolutely necessary-. <br />If y ou do, separa:: the resulting wastevvater and evaluate h. <br />• Latedtoi\tnU on F-tui Ule mfthiUnt cniondt. mdthyi tihyi :t:raehiaru r.ltrt :oiutne and nttv <br />iWliliiJ
