          Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
   Overexposure may cause coughing, shortness of breath, dizziness, central
nervous system depression, intoxication and collapse.  It may cause 
irritation to the respiratory tract and to other mucous membranes.
ROUTE OF EXPOSURE, SIGNS AND SYMPTOMS
INHALATION
   Overexposure may cause coughing, shortness of breath, dizziness, central
nervous system depression, intoxication and collapse.  It may cause 
irritation to the respiratory tract and to other mucous membranes.	      
EYE CONTACT
   Severely irritating.  If not removed promptly, will injure eye tissue,
which can result in permanent damage.   
SKIN CONTACT
   Frequent or prolonged contact may irritate and cause dermatitis.  Low
order of toxicity.
INGESTION
   Low order of toxicity.  Small amounts of the liquid aspirated into the
respiratory system during ingestion, or from vomiting, may cause 
bronchiopneumonia or pulmonary edema.   
SUMMARY OF CHRONIC HAZARDS
   Repeated or prolonged exposure may cause signs of central nervous system 
depression and respiratory irritation.  This material has been shown to
induce tumors in laboratory animals.   
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 flush with large amounts of water; use soap 
                   if available.  Remove contaminated clothing.
   If in EYES:     Immediately flush with large amounts of water for at least 
                   15 minutes.  Get prompt medical attention.
   If SWALLOWED:   If swallowed, DO NOT induce vomiting.  Keep at rest. Get 
                   prompt medical attention.

FLASH POINT                         LEL      UEL
    19 F (-7 C) SETA CC             2%       11.8%
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:  Extremely flammable - very low flash  
   point.  Vapors are heavier than air and may travel along ground or to low  
   spots at considerable distance to a source of ignition resulting in 
   potential flashback.  Burning liquid may float on water.  Heat may build 
   up pressure and rupture closed 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. 
   If transferring this material to other containers, ground all containers
   to avoid static electricity buildup and discharge which may ignite
   flammable    vapors.
OTHER PRECAUTIONS:  Avoid prolonged or repeated contact with skin or 
   clothing.  Empty containers may contain residues and vapors; treat as if 
   full and observe all products precautions.  Do not reuse empty containers.
   KEEP OUT OF REACH OF CHILDREN.
=============================================================================
          Section 8 -- EXPOSURE CONTROLS/PERSONAL PROTECTION
-----------------------------------------------------------------------------
RESPIRATORY PROTECTION (SPECIFY TYPE):  In confined poorly ventilated areas,
   use NIOSH/MSHA approved air purifying or supplied air purifying or 
   supplied air respirators.
VENTILATION - LOCAL EXHAUST:  Acceptable 
SPECIAL:  Explosion-proof equipment.
MECHANICAL (GENERAL):  Preferable
OTHER:  N/A
PROTECTIVE GLOVES:  Wear rubber gloves.

WORK/HYGIENIC PRACTICES:  Where use can result in skin contact, wash exposed
   areas thoroughly before eating, drinking, smoking, or leaving work area. 
   Launder contaminated clothing before reuse.
