Health Hazards Acute and Chronic:SULFUR HEXAFLUORIDE IS NONTOXIC AND IS
A SIMPLE ASPHYXIANT, LIBERATION OF A LARGE AMOUNT IN A CONFINED
AREA COULD DISPLACE THE AMOUNT OF OXYGEN IN AIR NECESSARY TO
SUPPORT LIFE.
Explanation of Carcinogenicity:THIS COMPOUND CONTAINS NO INGREDIENTS AT
CONCENTRATIONS OF 0.1% OR GREATER THAT ARE CARCINOGENS OR SUSPECT
CARCINOGENS.
Effects of Overexposure:EFFECTS OF EXPOSURE TO HIGH CONCENTRATIONS
WHICH DISPLACE THE OXYGEN IN THE AIR NECESSARY FOR LIFE ARE
HEADACHE, DIZZINESS, LABORED BREATHING AND EVENTUAL
UNCONSCIOUSNESS.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.
======================= First Aid Measures =======================
First Aid:INHALATION: CONSCIOUS PERSONS SHOULD BE TO FRESH AIR, IF
BREATHING HAS STOPPED, RESUSCITATE & GIVE O2. GET PROMPT MEDICAL
ASSISTANCE.
===================== Fire Fighting Measures =====================
Flash Point:NONFLAMMABLE
Extinguishing Media:NONFLAMMABLE INERT GAS
Fire Fighting Procedures:IF POSSIBLE WITHOUT RISK, MOVE CYLINDERS AWAY
FROM FIRE AREA. FROM A SAFE DISTANCE COOL CYLINDERS WITH A WATER
SPRAY UNTIL WELL AFTER FIRE IS OUT.
Unusual Fire/Explosion Hazard:CYLINDERS EXPOSED TO HEAT OR FLAMES MAY
VENT RAPIDLY OR EXPLODE.
================== Accidental Release Measures ==================
Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
APPROPRIATE PROTECTIVE EQUIPMENT. IF LEAK IS IN USER'S EQUIPMENT,

WHEN CONNECTING CYLINDER TO LOWER PRESSURE PIPING OR SYSTEMS. DO
NOT HEAT CYLIN DER BY ANY MEANS TO INCREASE DISCHARGE.
============= Exposure Controls/Personal Protection =============
Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH MASK OR SELF-
CONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR EMERGENCY
