Disposal Methods · 1 Eintrag

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.

Preventive Measures · 1 Eintrag

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.

DefinitionThe two most important crystalline sodium polyphosphates are the pyrophosphate (n = 2) and the tripolyphosphate, also called the triphosphate (n = 3). The term sodium polyphosphate also includes the system of vitreous sodium phosphates for which the mole ratio of Na2O/P2O5 is between 1 and 2.
