           Section 3 -- HAZARDS IDENTIFICATION
-----------------------------------------------------------------------------
SUMMARY OF ACUTE HAZARDS
   Irritation to respiratory system from fumes evolved during soldering. 
Eye contact may cause intense irritation and injury.
ROUTE OF EXPOSURE, SIGNS AND SYMPTOMS
INHALATION
   Irritation to respiratory system from fumes evolved during soldering.
EYE CONTACT
   Contact may cause intense irritation and injury.
SKIN CONTACT
   May cause skin irritation.
INGESTION
   Nausea, vomiting, irritation to digestive system.
SUMMARY OF CHRONIC HAZARDS
   Short term effects to liver and kidneys can occur. Chemical irritation
from continued skin contact can occur.  Continuous industrial use in small 
unventilated areas may result in sufficient inhalation of solder and flux 
fumes to cause lung damage and irritation of respiratory tract.
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 wash with soap and water.  Remove and wash 
                   any contaminated clothing.
   If in EYES:     Flush eyes with large amounts of water for 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.

EXTINGUSING MEDIA
   Foam, dry chemical, carbon dioxide or water fog.
SPECIAL FIRE FIGHTING PROCEDURES:  Wear self-contained full face piece
breathing apparatus and other protective clothing.  Hazardous decomposition
products possible (see Section 10).  May release ZnO and HCl fumes.
UNUSUAL FIRE AND EXPLOSION HAZARDS:  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:  Wipe up spills to
prevent footing hazard.  Avoid flushing into sewers, drains, waterways and
soil.  Wear protective clothing during clean up.
=============================================================================
           Section 7 -- HANDLING AND STORAGE
-----------------------------------------------------------------------------
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING:  Keep container closed and 
upright when not in use.   Store flux at ambient conditions.  Wash thoroughly 
after handling to remove all residue.
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. 
=============================================================================
           Section 8 -- EXPOSURE CONTROLS/PERSONAL PROTECTION
-----------------------------------------------------------------------------
RESPIRATORY PROTECTION (SPECIFY TYPE):  In confined, poorly ventilated areas,
use NIOSH/MSHA approved air purifying or supplied air respirators during
soldering  operations until fumes have dissipated. 
VENTILATION - LOCAL EXHAUST:  Acceptable 
SPECIAL:  N/A
MECHANICAL (GENERAL):  Acceptable 
OTHER:  N/A
PROTECTIVE GLOVES:  Wear rubber gloves.
EYE PROTECTION:  Safety glasses (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.
