                     IN EXTREME CASES UNCONSCIOUSNESS MAY OCCUR.  ASPHYXIATION
                     MAY BE NOTED BY A SUDDEN LOSS OF CONSCIOUSNESS;  DEATH MAY
                     QUICKLY FOLLOW.

EYE CONTACT:  IF DIRECT LIQUID CONTACT OCCURS, FLUSH EYES WITH WATER.  GET
              MEDICAL ATTENTION.
SKIN CONTACT: IF DIRECT LIQUID CONTACT OCCURS, FLUSH WITH WATER.  IF FROSTBITE
              OR BURN OCCURS, GET MEDICAL ATTENTION.
INHALATION:   REMOVE VICTIM TO FRESH AIR AND PROVIDE OXYGEN IF BREATHING IS
              DIFFICULT.  GIVE ARTIFICIAL RESPIRATION IF NOT BREATHING.  GET
              MEDICAL ATTENTION.

SECTION VI                       SUPPLEMENTAL HEALTH INFORMATION
_______________________________________________________________________________
WHILE THERE IS NO EVIDENCE THAT EXPOSURE TO INDUSTRIALLY ACCEPTABLE LEVELS OF
HYDROCARBONS HAVE PRODUCED CARDIAC EFFECTS IN HUMANS, ANIMAL STUDIES HAVE SHOWN
THAT INHALATION OF HIGH VAPOR LEVELS OF BUTANE HAVE PRODUCED CARDIAC
SENSITIZATION.  SUCH SENSITIZATION MAY CAUSE FATAL CHANGES IN HEART RHYTHMS.
THIS LATTER EFFECT WAS SHOWN TO BE ENHANCED BY HYPOXIA OR THE INJECTION OF
ADRENALIN-LIKE AGENTS.

SPECIAL FIRE FIGHTING PROCEDURES AND PRECAUTIONS:
  DANGER.  EXTREMELY FLAMMABLE.  CLEAR FIRE AREA OF UNPROTECTED PERSONNEL AND
  ISOLATE.  DO NOT ENTER CONFINED FIRE SPACE WITHOUT FULL BUNKER GEAR (HELMET
  WITH FACE SHIELD, BUNKER COATS, GLOVES AND RUBBER BOOTS), INCLUDING A
  POSITIVE PRESSURE NIOSH APPROVED SELF-CONTAINED BREATHING APPARATUS.  COOL

_______________________________________________________________________________
SECTION X                        EMPLOYEE PROTECTION
_______________________________________________________________________________
RESPIRATORY PROTECTION:
  USE A NIOSH-APPROVED RESPIRATOR AS REQUIRED TO PREVENT OVEREXPOSURE.  IN
  ACCORD WITH 29 CFR 1910.134, USE EITHER AN ATMOSPHERE-SUPPLYING RESPIRATOR OR
  AN AIR-PURIFYING RESPIRATOR FOR ORGANIC VAPORS.
PROTECTIVE CLOTHING
  AVOID LIQUID CONTACT WITH EYES.  WEAR SAFETY GLASSES OR GOGGLES AS
  APPROPRIATE.  AVOID LIQUID CONTACT WITH SKIN.  WEAR PROTECTIVE CLOTHING AS
  APPROPRIATE.
ADDITIONAL PROTECTIVE MEASURES:
  USE EXPLOSION-PROOF VENTILATION AS REQUIRED TO CONTROL VAPOR CONCENTRATIONS.
_______________________________________________________________________________
SECTION XI                       ENVIRONMENTAL PROTECTION
_______________________________________________________________________________
SPILL OR LEAK PROCEDURES:
  DANGER!  EXTREMELY FLAMMABLE.  ELIMINATE ALL SOURCES OF IGNITION.  ISOLATE
  HAZARD AREA AND DENY ENTRY TO UNNECESSARY OR UNPROTECTED PERSONNEL.  STAY
  UPWIND AND KEEP OUT OF LOW AREAS.  NOTIFY LOCAL FIRE DEPARTMENT.  DISPERSE
  ANY VAPOR CLOUD WITH A SUSTAINED FLOW OF WATER SPRAY.  SHUT OFF SOURCE OF
  LEAK ONLY IF IT CAN BE DONE SAFELY.
_______________________________________________________________________________
SECTION XII                      SPECIAL PRECAUTIONS
_______________________________________________________________________________
KEEP LIQUID AND VAPOR AWAY FROM HEAT, SPARKS AND FLAME.  SURFACES THAT ARE
SUFFICIENTLY HOT MAY IGNITE EVEN LIQUID PRODUCT IN THE ABSENCE OF SPARKS OR
FLAME.  EXTINGUISH PILOT LIGHTS, CIGARETTES AND TURN OFF OTHER SOURCES OF
IGNITION PRIOR TO USE AND UNTIL ALL VAPORS ARE GONE.  VAPORS MAY ACCUMULATE AND
TRAVEL TO IGNITION SOURCES DISTANT FROM THE HANDLING SITE; FLASHFIRE CAN
RESULT.  KEEP CONTAINERS CLOSED WHEN NOT IN USE.  USE WITH ADEQUATE VENTILATION.
CONTAINERS, EVEN THOSE THAT HAVE BEEN EMPTIED, CAN CONTAIN EXPLOSIVE VAPORS.
DO NOT CUT, DRILL, GRIND, WELD OR PERFORM SIMILAR OPERATIONS ON OR NEAR
CONTAINERS.
STATIC ELECTRICITY MAY ACCUMULATE AND CREATE A FIRE HAZARD.  GROUND FIXED
EQUIPMENT.  BOND AND GROUND TRANSFER CONTAINERS AND EQUIPMENT.
THE MERCAPTAN ODOR OF THIS MATERIAL MAY DISSIPATE OR MAY OTHERWISE NOT BE
DISCERNIBLE BY SOME INDIVIDUALS.  EXTRA PRECAUTIONS SHOULD BE OBSERVED AROUND
POSSIBLE POINTS OF LPG RELEASE.
