Sicherheit und Schutzausrüstung
Disposal Methods
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
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.
Allowable Tolerances
Residues of calcium phosphate are exempted from the requirement of a tolerance when used as a solid diluent or carrier in accordance with good agricultural practices as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest. /Calcium phosphate/

Because calcium hydrogen phosphate is incongruently soluble, it is typically contaminated with various amounts (6-10%) of dicalcium phosphate and free phosphorus acid resulting from in-process disproportionation of the monocalcium salt.
Since phosphorus acid impurity may render the product hygroscopic and absorbed water and acid catalyzes further disproportionation, excess lime may be added to industrial monocalcium phosphate to ensure removal of residual free phosphoric acid. Therefore the product may contain dicalcium phosphate.
... The hygroscopic nature of anhydrous monocalcium phosphate limited its commercial applications. However, the addition of small amounts of potassium (+1), sodium (+1), and aluminum (+3) ions to the crystallization mother liquor ... results ... glassy coating protects the calcium phosphate from moisture and greatly improves its handling properties and performance in several applications ...
