OSHA and ACGIH have established limits for particulates not otherwise regulated (PNOR) and
particulates not otherwise classified (PNOC) which are the least stringent exposure limits
applicable to dusts.
Respiratory protection
Avoid breathing dust. In case of insufficient ventilation, use approved respiratory protective
equipment as described in U.S. OSHA 29 CFR 1910.134 or European Standard EN149.
Hand/Skin protection
Wear protective gloves is recommended; wash hands and contaminated skin thoroughly after
handling.

11. TOXICOLOGICAL INFORMATION
Laboratory data
Data from ICL Performance Products LP single-dose (acute) animal studies with this material are
given below:
Oral - rat LD50: > 2980 mg/kg; slightly toxic
Dermal - rabbit LD50: > 7940 mg/kg; practically nontoxic
Eye Irritation - rabbit: 11.1/110.0; moderately irritating

12. ECOLOGICAL INFORMATION
ICL Performance Products LP Material Safety Data Sheet
Material: Tetrapotassium Pyrophosphate Anhydrous Page 5 of 6
Reference No.: AST10058 November 1, 2005
Environmental toxicity
The following data have been classified using the criteria adopted by the European Economic
Community (EEC) for aquatic organism toxicity
48-hr EC50 Daphnia magna: > 100 mg/l, Practically Nontoxic
96-hr LC50 Mysid Shrimp > 100 mg/l, Practically Nontoxic
96-hr LC50 Rainbow trout: > 100 mg/l, Practically Nontoxic
Environmental fate
This product is considered to have low toxicity to aquatic and estuarine species. Inorganic
phosphates, including this product, at high concentrations in the environment have the potential
to cause eutrophication in aquatic systems. This condition is characterized by excessive algal
growth, and subsequent decreases in oxygen levels. In general, proper use and disposal of this
product should pose no adverse ecological risk.
Inorganic compounds in contact with the soil, sub-surface or surface waters may be taken up by
plants and utilized as essential nutrients. Phosphates may also form precipitates, usually with
calcium or magnesium. The resultant compounds are insoluble in water and become a part of the
soil or sediment. The term biodegradability, as such, is not applicable to inorganic compounds.
13. DISPOSAL CONSIDERATIONS
