A mercury vacuum is a vacuum cleaner specifically designed to collect mercury (the metallic element, not the planet), for instance to clean up spills of the element. It is a requirement of the U.S. EPA that a mercury vacuum cleaner be used to clean up mercury spills (if an alternative method is used, a description of the method must be submitted to the EPA Administrator in a Notification of ...
Mercury vapor is the primary hazard of elemental mercury. As a result, containers of mercury are securely sealed to avoid spills and evaporation. Heating of mercury, or of compounds of mercury that may decompose when heated, should be carried out with adequate ventilation in order to minimize exposure to mercury vapor.
Spill containment is where spills of chemicals, oils, sewage etc. are contained within a barrier or drainage system rather than being absorbed at the surface. One method is to use an inflatable stopper or pneumatic bladder which is inserted into the outflow of a drainage system to create a containment vessel.
Mercury cell chlor-alkali production is a significant user of mercury and a source of mercury releases to the environment. The mercury used in this process acts as a catalyst in the chlorine production process. Best practices, such as proper waste management, can minimize the release of mercury.
Mercury can enter seas and the open ocean as a result of the down stream movement and re-deposition of contaminated sediments from urban estuaries. [12] For example, high total Hg content up to 5 mg/kg and averaging about 2 mg/kg occur in the surface sediments and sediment cores of the tidal River Mersey, UK, due to discharge from historical industries located along the banks of the tidal ...
The mercury contamination in Kodaikanal originated at a thermometer factory owned by Hindustan Unilever. Unilever acquired the thermometer factory from cosmetics maker Pond's India Ltd. Pond's moved the factory from the United States to India in 1982 after the plant owned there by its parent, Chesebrough-Pond's, had to be dismantled following increased awareness in developed countries of ...
Mercury contamination in Grassy Narrows was an uncontrolled discharge of between 9,000 kilograms (20,000 lb) and 11,000 kilograms (24,000 lb) of mercury from the Dryden Mill's chloralkali plant in Dryden into the headwaters of the Wabigoon River in the Kenora District of Northwestern Ontario from 1962 until 1970.

A spill pallet is a bunded secondary containment item that is designed to hold containers of oil, hazardous liquids, and fuels, typically in either a 200-litre (44 imp gal; 53 US gal) drum or in an intermediate bulk container. It is called a 'secondary containment item' because it is designed to catch the leaks and spill of the container's ...
