A mercury vacuum cleaner should be designed to prevent generation of airborne mercury typically through the use of an activated carbon charcoal filter in addition to any particulate filters. The ends of hoses should be capped after each use; and after vacuuming, the area should be washed down. Users of mercury vacuum cleaners should be trained in the handling of hazardous materials.
In order to minimize environmental risks, a mercury vacuum cleaner should be designed with safety features that prevent airborne mercury emission, such as activated carbon charcoal filters and particulate filters. Users must also follow proper procedures for disposing of used hoses and cleaning the area after use, and receive training on safe handling practices for hazardous materials.
