           Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
   May cause irritation to skin, eyes, and respiratory tract. May be harmful 
if swallowed or inhaled.  Many of the systemic effects given below were taken 
from toxicity information for other phosphates.
ROUTE OF EXPOSURE, SIGNS AND SYMPTOMS
INHALATION
   May cause irritation to the respiratory tract. Symptoms may include coughing
and shortness of breath.
EYE CONTACT
   May cause irritation, redness and pain.
SKIN CONTACT
   May cause skin irritation.
INGESTION
   Phosphates are slowly and incompletely absorbed when ingested, and seldom 
result in systemic effects.  Such effects, however, have occurred. Symptoms 
may include vomiting, lethargy, diarrhea, blood chemistry effects, heart 
disturbances and central nervous system effects. The toxicity of phosphates is 
because of their ability to sequester calcium. Systemic acidosis may result as
this material is believed to hydrolyze into phosphoric acid when ingested.
SUMMARY OF CHRONIC HAZARDS
   None known.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
  Individuals with pre-existing or chronic diseases of the eyes, skin,
  respiratory system, cardiovascular system, gastrointestinal system, liver,
  or kidneys may have increased susceptibility to excessive exposure.
=============================================================================
           Section 4 -- FIRST AID MEASURES
-----------------------------------------------------------------------------
   If INHALED:     If overcome by exposure, remove victim to fresh air
                   immediately.  Give oxygen or artificial respiration as 
                   needed.  Obtain emergency medical attention.  Prompt 
                   action is essential.
   If on SKIN:     Immediately wash with soap and water.  Remove and wash 
                   any contaminated clothing.
   If in EYES:     Flush eyes with large amounts of water for 15 minutes.
                   Get medical attention if irritation persists. 
   If SWALLOWED:   If swallowed, call a physician immediately.  Only induce 
                   vomiting at the instruction of a physician.  Never give 
                   anything by mouth to an unconscious person.
