           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 skin with plenty of water for at least 15
                   minutes while removing contaminated clothing and shoes. Wash 
                   clothing before reuse. 
   If in EYES:     Immediately flush eyes with gentle but large stream of water
                   for at least 15 minutes, lifting lower and upper eyelids 
                   occasionally. Call a physician immediately. 
   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.
=============================================================================
           Section 5 -- FIRE FIGHTING MEASURES
-----------------------------------------------------------------------------
EXTINGUSING MEDIA
   Use agents appropriate for surrounding fires.
SPECIAL FIRE FIGHTING PROCEDURES:  Wear self-contained breathing apparatus 
   (SCBA) and other protective clothing.  Hazardous decomposition products 
possible (see Section 10).  Evacuate immediate area.  
UNUSUAL FIRE AND EXPLOSION HAZARDS:  Toxic fumes of chlorine, and HCL may be 
produced in fire.
=============================================================================
           Section 6 -- ACCIDENTAL RELEASE MEASURES
-----------------------------------------------------------------------------
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:  Evacuate area and 
keep upwind until gas has dispersed.  Dike spill.  Dilute with water fog 
(direct application of alkali may cause violent splattering).  Neutralize with
sodium bicarbonate.  Persons not wearing protective equipment and clothing 
should be restricted from areas of spills or leaks until clean up has been 
completed.  
=============================================================================
           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.  
This product will attack glass, concrete and certain metals.  Store only in 
plastic containers.  DO NOT USE METAL CANS.
