           Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
   Exposure to human tissue will result in irritation and chemical burns.
ROUTE OF EXPOSURE, SIGNS AND SYMPTOMS
INHALATION
   Extremely corrosive to respiratory system.
EYE CONTACT
   Corrosive, contact causes severe eye burns.
SKIN CONTACT
   Corrosive to skin.
INGESTION
   Poison!  Swallowing large quantities can cause death and burns to digestive 
system.
SUMMARY OF CHRONIC HAZARDS
      Exposure to human tissue will result in irritation and chemical burns. 
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
  Individuals with pre-existing or chronic diseases of the eyes, skin 
or persons with chemical sensitivity 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:     Flush with large amounts of water.  If irritation or burns 
                   occur, seek immediate medical attention.
   If in EYES:     Flush with large amounts of water for at least 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.

   None                             N/A      N/A
EXTINGUSING MEDIA
   Use agents suitable for surrounding fires.
SPECIAL FIRE FIGHTING PROCEDURES:  Wear self-contained breathing apparatus 
   (SCBA) and other protective clothing.  Hazardous decomposition products 
possible (see Section 10).  Dike area as run-off may create additional 
environmental contamination 
UNUSUAL FIRE AND EXPLOSION HAZARDS:  Decomposition forms toxic fumes of sodium
oxide.  Flammable gas may be produced on contact with metals.
=============================================================================
           Section 6 -- ACCIDENTAL RELEASE MEASURES
-----------------------------------------------------------------------------
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:  Keep people away. 
Wear chemical protective clothing.  Stop discharge if possible.  Isolate and 
remove discharged material.  Flush and clean area with water 
=============================================================================
           Section 7 -- HANDLING AND STORAGE
-----------------------------------------------------------------------------
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING:    Keep container closed  and 
upright when not in use.  Store only in polyethylene or glass containers.  DO 
NOT USE METAL CONTAINERS.
OTHER PRECAUTIONS:  Do not permit workers to handle Renewz without proper 
training or proper protective equipment.  Store in well-sealed containers, 
which are protected from physical damage. Empty containers may contain residues 
and vapors; treat as if full and observe all product precautions.  Do not 
reuse container. 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 self-contained breathing apparatus.  None required for 
normal use in adequately ventilated areas where TLV is not exceeded.  
VENTILATION - LOCAL EXHAUST:  Acceptable
SPECIAL:  Explosion proof
MECHANICAL (GENERAL):  Preferable
OTHER:  N/A
PROTECTIVE GLOVES:  Rubber or neoprene 
EYE PROTECTION:  Chemical splash goggles (ANSI Z-87.1 or equivalent)
OTHER PROTECTIVE CLOTHING OR EQUIPMENT:  Coveralls recommended.
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.
