          Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
   Irritation to eyes, nose and throat; drowsiness, narcosis, tremors and 
   other CNS effects at high concentration.
ROUTE OF EXPOSURE, SIGNS AND SYMPTOMS
INHALATION
   Nasal and respiratory irritation, dizziness, narcosis, headache, nausea,
CNS depression and unconsciousness.
EYE CONTACT
   Watering, blurred vision, inflammation and irritation which can result in
corneal injury.
SKIN CONTACT
   Irritation, dermatitis.
INGESTION
   Nausea, vomiting; CNS depression; irritation of gastrointestinal tract,
liver and peritoneal wall; lung congestion.
SUMMARY OF CHRONIC HAZARDS
   Skin irritation and dermatitis.  Possible liver and kidney damage.
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 exposures.
=============================================================================
          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 flush with large amounts of water for at least 
                   15 minutes.  Get prompt medical attention.
   If in EYES:     Flush eyes with large amounts of water for 15 minutes.
                   Get medical attention.
   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.

EXTINGUSING MEDIA
   Foam, dry chemical, carbon dioxide or water fog.
SPECIAL FIRE FIGHTING PROCEDURES:  Wear self-contained breathing apparatus 
   (SCBA) and other protective clothing.  Hazardous decomposition products 
   possible (see Section 10).
UNUSUAL FIRE AND EXPLOSION HAZARDS:  Combustible - moderate flash point. 
   Vapors heavier than air and may travel along the ground or to low spots 
   at considerable distances to a source of ignition resulting in potential
   flashback.  Burning liquid may float on water.  Heat may build up   
   pressure and rupture containers. 
=============================================================================
          Section 6 -- ACCIDENTAL RELEASE MEASURES
-----------------------------------------------------------------------------
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:  Remove all 
   sources of ignition.  Use absorbent materials to prevent footing hazard 
   and to contain.  Ventilate area with natural or explosion-proof, forced 
   air ventilation.  Avoid flushing into sewers, drains, waterways, and soil. 
   Wear protective clothing and respiratory protection during cleanup.  
=============================================================================
          Section 7 -- HANDLING AND STORAGE
-----------------------------------------------------------------------------
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING:  Keep container closed and
   upright when not in use.  Do not store near heat, sparks, or open flames. 
OTHER PRECAUTIONS:  Avoid prolonged or repeated contact with skin or 
   clothing.  Empty containers may contain residues; treat as if full and
   observe all products precautions.  Do not reuse empty containers.  
   KEEP OUT OF REACH OF CHILDREN.
