5.6 DisposalMethodsSRP: 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.

5.7 Formulations/PreparationsTypical specifications of commercial chloroformates: purity, 98%; phosgene,Commercial products have concentrations of 97-99 wt% /chloroformic esters/97%

5.8 Other Preventative MeasuresSRP: 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 protectionequipment should be worn even when contact lenses are in place.

5.9 Protective Equipment and ClothingVery irritating to eyes and skin.
