4. FIRST AID MEASURES
General
Likely Routes of Exposure: Skin contact and inhalation
Eye contact
No more than slightly irritating based on toxicity studies. The dry powder may cause foreign body
irritation in some individuals. Immediate first aid is not likely to be required. However, this
material can be removed with water. Remove material from eyes, skin and clothing. Wash
heavily contaminated clothing before reuse.
Skin contact
No more than slightly toxic or slightly irritating based on toxicity studies. Prolonged contact with
the dry powder may cause drying or chapping of the skin. Immediate first aid is not likely to be
required. However, this material can be removed with water. Remove material from eyes, skin
and clothing. Wash heavily contaminated clothing before reuse.
Inhalation:
This product may cause coughing, chest tightness, runny nose, chest pain, and burning throat. If
inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult,
give oxygen.
Ingestion
No more than slightly toxic if swallowed based on toxicity tests. No significant adverse health
effects are expected to develop if only small amounts (less than a mouthful) are swallowed.
Swallowing large quantities may cause gastrointestinal tract irritation, nausea, vomiting, and
diarrhea. If swallowed, immediate first aid is not likely to be required. A physician or Poison
Control Center can be contacted for advice.
5. FIRE FIGHTING MEASURES

basis. Flush residual spill area with water.
Refer to Section 13 for disposal information and Sections 14 and 15 for reportable quantity
information.
7. HANDLING AND STORAGE
Handling
Avoid breathing dust.
Keep container closed.
Use only with adequate ventilation.
Emptied container retains product residue. Observe all labeled safeguards until container is
cleaned, reconditioned or destroyed.
Engineering measures
Provide natural or mechanical ventilation to control exposure levels below occupational exposure
limits. The use of local mechanical exhaust ventilation is preferred at sources of air
contamination such as open process equipment. Consult National Fire Protection Association
(NFPA) Standard 91 for design of exhaust systems.
Storage
Store in a cool, dry place to maintain product performance.

Respiratory protection
Avoid breathing dust. Use NIOSH/MSHA approved respiratory protection equipment when
airborne exposure limits are exceeded (see below). Consult the respirator manufacturer to
determine appropriate type equipment for a given application. Observe respirator use limitations
specified by NIOSH/MSHA or the manufacturer. Respiratory protection programs must comply
with 29 C.F.R. 1910.134.
Hand/skin protection
Although this product does not present a significant skin concern, minimize skin contamination by
following good industrial practice. Wearing protective gloves is recommended. Wash hands and
contaminated skin thoroughly after handling.
Eye protection
This product does not cause significant eye irritation or eye toxicity requiring special protection.
Use good industrial practice to avoid eye contact.

Rats fed Sodium Tripolyphosphate Anhydrous in their diet for two years exhibited decreased
growth, increased kidney/body weight ratios, and kidney changes. No birth defects were noted in
rabbits given Sodium Tripolyphosphate Anhydrous orally during pregnancy. No effects were
seen on the ability of male and female rats to reproduce when fed Sodium Tripolyphosphate
Anhydrous for 3 successive generations. Sodium Tripolyphosphate Anhydrous has generally
produced no genetic changes in a variety of standard tests using animals and animal or bacterial
cells. Genetic changes were reported in a standard test using yeast cells.
