           Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
   Causes irreversible eye damage and skin irritation.
ROUTE OF EXPOSURE, SIGNS AND SYMPTOMS
INHALATION
   N/A 
EYE CONTACT
   Corrosive: Causes irreversible eye damage.
SKIN CONTACT
   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
  May induce severe gastroenteric distress (vomiting, gastroenteric pain, and
local corrosion and hemorrhages), prostration, anuria, hematuria, anemia, 
increase in white blood cells, icterus, coma,respiratory difficulties, and 
circulatory failure. 
=============================================================================
           Section 4 -- FIRST AID MEASURES
-----------------------------------------------------------------------------
   If INHALED:     N/A
   If on SKIN:     Immediately wash with soap and water.  Remove and wash

   If in EYES:     Flush eyes with large amounts of water for 15 minutes.
                   Get medical attention if irritation persists. 
   If SWALLOWED:   Call a doctor or get medical attention.  Do not induce 
                   vomiting or give anything by mouth to an unconscious person.
                   Drink promptly a large quantity of milk, egg whites, gelatin 
                   solution, or if these are not available, drink large
                   quantities of water.  Avoid alcohol.
