• Use closed containers for collecting and storing recovered or new solvent.
• Keep lids on all containers at all times.
• Minimize the time machine doors and traps remain open:
• Open button traps and lint baskets only long enough to clean them.
• Put clothes in the machine and close the machine quickly.

• Clean the filters that precede the carbon filters weekly.
• Clean drying sensors weekly.
• Clean lint screens daily to avoid clogging fans and condensers.
• Clean lint buildup on cooling condenser coils weekly.

Manage Materials Safely and Wisely—

• Properly label all perc and waste containers.
• Size garment loads correctly for the machine you are using.
• Keep storage and work areas clean and well-organized.
• Use spigots, pumps, and funnels when transferring materials and wastes.

• Conduct weekly visual inspections of all machines and components.
• Check air relief valves for proper closure.
• Properly adjust the perc/water separator to keep perc out of sewered wastewater.
• Adjust the in- and out-temperatures on the heater's condensing coil to within 10º F of each other to improve perc recovery.
• Check the baffle assembly in the cleaning machine biweekly.
• Keep an accurate and up-to-date log of all inspections.
• Use solvent leak detectors to locate and repair leaks.
• Measure perc emissions weekly using a colorimetric tube test.
• Secure hose connections and couplings to reduce emissions.

• If you find a problem, fix it immediately or ASAP.
• Periodically replace gaskets, seals, and valves:
• in old transfer machines;
• on the door to the button trap;
• on dryer deodorizer and aeration valves; and
• around cleaning machine door.
• Tighten the enclosure around the cleaning machine.
• Repair holes in air and exhaust ducts.
• Keep a log of all repairs made to machines and other equipment.
