Health Hazards Acute and Chronic:HELIUM IS NONTOXIC, BUT MAY CAUSE
SUFFOCATION BY DISPLACING OXYGEN IN THE AIR. EXPOSURE TO
OXYGEN-DEFICIENT ATMOSPHERES MAY CAUSE DIZZINESS, NAUSEA, VOMITING,
DIMINISHED MENTAL ALERTNESS, LOSS OF CONS CIOUSNESS, AND DEATH. IT
SHOULD BE RECOGNIZED THAT COLLAPSE & ASPHYXIATION MAY OCCUR WITHOUT
ANY OF THE ABOVE SYMPTOMS.

FRESH AIR. IF VICTIM IS NOT BREATHING, ADMINISTER ARTIFICIAL
RESPIRATION. IF BREATHING IS DIFFICULT, ADMINISTER OXYGEN. OBTAIN
PROMPT MEDICAL ATTENTION.

Extinguishing Media:MATERIAL NONFLAMMABLE. HELIUM NEITHER
BURNS/SUPPORTS COMBUSTION. USE EXTINGUISH MEDIA APPROPRIATE FOR
SURROUNDING FIRE.
Fire Fighting Procedures:NONE. HELIUM WILL ACT AS A SIMPLE ASPHYXIANT
IF IT DISPLACES OXYGEN. IF POSSIBLE, REMOVE HELIUM CYLINDERS FROM
FIRE AREA OR COOL W/WATER. SCBA MAY BE REQUIRED.
Unusual Fire/Explosion Hazard:PRESSURE CAN BUILD UP DUE TO HEAT AND
CYLINDER MAY EXPLODE IF PRESSURE RELIEF DEVICES SHOULD FAIL TO
RELIEVE PRESSURE.

Spill Release Procedures:EVACUATE UNNEEDED PERSONNEL. SHUT OFF HELIUM
SOURCE IF POSS VENT ENCLOSED AREAS OR REMOVE CYLINDERS TO OUTDOORS
TO PREVENT FORMATION OF OXYGEN-DEFICIENT ATMOSPHERES. IF LEAKING
FROM CONTAINER/VALVE, C ONTACT CLOSEST BIG THREE INDUSTRIES OR
SUPPLIER.

Handling and Storage Precautions:STORE AND USE WITH ADEQUATE
VENTILATION. CYLINDERS SHOULD BE STORED UPRIGHT WITH VALVE

WHERE CYLINDERS ARE STOR ED TO EXCEED 125 F (52 C).

Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS OR
POSITIVE PRESSURE AIR LINE WITH MASK IN OXYGEN-DEFICIENT
ATMOSPHERES. RESPIRATORS WILL NOT FUNCTION.
Ventilation:ADEQUATE TO AVOID LOWERING OXYGEN CONTENT TO BELOW 19.5%
(OXYGEN DEFICIENT ATMOSPHERE). LOCAL/MECHANICAL EXHAUST-YES.
Eye Protection:SAFETY GLASSES RECOMMENDED.
Other Protective Equipment:SAFETY SHOES WHEN HANDLING CYLINDERS.
