4.1 Other Preventative Measures: SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

4.2 Hazard Class: 6.1

4.2 Hazard Declaration: H301-H331-H373-H410

4.2 DisposalMethods: SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Recycling: As the price of selenium is very high, recovery of it by processing selenium-containing waste is economical. For example, selenium refineries are equipped with wet scrubbers that employ an approx 50% soln of hydrobromic acid containing free bromine. The acid fumes are adsorbed in a lime and soda bed, and the selenium separated from the hydrobromic acid soln by distillation is recycled. Otherwise, solid or sludgy selenium-containing wastes from the manufacture or repair of xerox drums or from paint production are disposed of in special dumps. Recommendable methods: Chemical reduction, solidification & landfill. Not recommendable methods: Thermal destruction & discharge to sewer. Peer review: Reduction with SO2 /sulfur dioxide/ to SE /selenium/ metal. Do not use metal and acids to reduce disodium selenate as this will produce toxic gaseous hydrogen selenide.
