Make repairs promptly. Keep all containers covered to prevent evaporation and spillage. Provide secondary containment in areas where solvents are stored. Keep waste streams separate to increase their potential for reuse, recycling, or treatment. Don't allow nonhazardous materials to become contaminated with hazardous materials, as this will result in all of the waste needing to be treated as hazardous waste.
Clean lint screens regularly to avoid clogging of fans and condensers.
Modifying processes, equipment, and operating practices. More major modifications may be economically feasible when all savings, such as avoided disposal costs and avoided liability, are taken into consideration. Use spigots and pumps when dispensing new materials and funnels when transferring wastes to storage containers to reduce the possibilities of spills. Modify processes and equipment to reduce solvent vapor loss of to recover solvents for reuse. Add-on carbon adsorption or refrigeration units can recover valuable solvent.
