MIS is a unique formulation that transforms liquid mercury into an immobile solid amalgam, which almost completely suppresses the emission of mercury vapours. Mercury is a highly toxic material and its release into the atmosphere and the water system can have a serious impact. When mercury is spilled, hazardous vapour levels can quickly develop, thus it is important to treat these spills promptly and effectively. Once activated, works on contact, the solid granules can be easily and safely removed with pick up tools or vacuum devices. Effective on spills in drains and to make mercury waste safer for transport. Weight 14kgs.
