(1) All surfaces must be maintained as free as practicable of accumulations of cadmium.
(2) All spills and sudden releases of material containing cadmium must be cleaned up as soon as possible.
(3) Surfaces contaminated with cadmium must, wherever possible, be cleaned by vacuuming or other methods that minimize the likelihood of cadmium becoming airborne.
(4) HEPA-filtered vacuuming equipment or equally effective filtration methods must be used for vacuuming. The equipment must be used and emptied in a manner that minimizes the reentry of cadmium into the workplace.
(5) Shoveling, dry or wet sweeping, and brushing may be used only where vacuuming or other methods that minimize the likelihood of cadmium becoming airborne have been tried and found not to be effective.
(6) Compressed air must not be used to remove cadmium from any surface unless the compressed air is used in conjunction with a ventilation system designed to capture the dust cloud created by the compressed air.
(7) Waste, scrap, debris, bags, containers, personal protective equipment, and clothing contaminated with cadmium and consigned for disposal must be collected and disposed of in sealed impermeable bags or other closed, impermeable containers. These bags and containers must be labeled in accordance with WAC
