=====================  Hazards Identification  =====================

LD50 LC50 Mixture:NOT RELEVANT
Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:TARGET ORGANS:NONE. ACUTE- HELIUM IS A
    SIMPLE ASPHYXIANT. HELIUM IS NONTOXIC, BUT CAN PRODUCE SUFFOCATION
    BY DISPLACING OXYGEN. PROLONGED INHALATION OF HIGH CONCENTRATIONS
    CAN CAUSE UNCONSCIOUSNESS, C ONVULSIVE MOVEMENTS, POSSIBLE DEATH.
    THIS PRODUCT IS A GAS. CANNOT BE SWALLOWED OR CONTACTED. CHRONIC-
    NONE.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:DIZZINESS, DROWSINESS, HEADACHE, NAUSEA,
    VOMITING, EXCESS SALIVATION, DIMINSHED MENTAL ALERTNESS,
    UNCONSCIOUSNESS, DEATH
Medical Cond Aggravated by Exposure:NONE

=======================  First Aid Measures  =======================

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
    OVEREXPOSURE. RESCUE PERSONNEL SHOULD WEAR SELF-CONTAINED BREATHING
    APPARATUS. INHALED:REMOVE TO FRESH AIR. PROVIDE OXYGEN/CPR IF
    NEEDED. EYE/SKIN /ORAL:UNLIKELY (GAS)

=====================  Fire Fighting Measures  =====================

Flash Point:NONE
Lower Limits:NOT RELEVANT
Upper Limits:NOT RELEVANT
Extinguishing Media:USE WATER FOG, CARBON DIOXIDE, FOAM, OR DRY
    CHEMICAL FOR SURROUNDING FIRE. KEEP FIRE-EXPOSED CYLINDERS COOL
    WITH WATER.
Fire Fighting Procedures:WEAR PROTECTIVE CLOTHING AND NIOSH-APPROVED
    SELF-CONTAINED BREATHING APPARATUS IF NEEDED.
Unusual Fire/Explosion Hazard:CYLINDERS MAY VENT RAPIDLY AND RUPTURE
    VIOLENTLY. MOST CYLINDERS ARE DESIGNED TO VENT CONTENTS WHEN
    EXPOSED TO ELEVATED TEMPERATURES.

==================  Accidental Release Measures  ==================

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
    APPROPRIATE PROTECTIVE EQUIPMENT. VENTILATE AREA. IF LEAK IS FROM
    CYLINDER OR ITS VALVE, CONTACT AIR PRODUCTS. THE ATMOSPHERE MUST
    HAVE AT LEAST 19.5% OX YGEN BEFORE PERSONNEL CAN BE ALLOWED INTHE
    AREA.
Neutralizing Agent:NOT RELEVANT

======================	Handling and Storage  ======================

Handling and Storage Precautions:STORE CYLINDERS UPRIGHT, SECURE, IN
    COOL, DRY, VENTILATED AREA BELOW 125F. PROTECT FROM PHYSICAL
    DAMAGE. FULL & EMPTY CYLINDERS SHOULD BE SEGREGATED.
Other Precautions:WARNING! EXPOSURES TO FATAL CONCENTRATIONS OF HELIUM
    COULD OCCUR WITHOUT ANY SIGNIFICANT WARNINGS. EXPOSURE TO
    ATMOSPHERES CONTAINING 8-10% OR LESS OXYGEN WILL BRING
    UNCONSCIOUSNESS SO QUICKLY THAT IN DIVIDUALS CANNOT HELP
    THEMSELVES.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:IF OXYGEN LEVEL IS BELOW 19.5%, USE
    NIOSH-APPROVED SELF-CONTAINED BREATHING APPARATUS OR SUPPLIED AIR
    RESPIRATOR, OPERATED IN POSITIVE PRESSURE MODE.
Ventilation:ADEQUATE
Protective Gloves:LEATHER WHEN HANDLING CYLINDERS
Eye Protection:GOGGLES/GLASSES RECOMMENDED
Other Protective Equipment:SAFETY SHOES WHEN HANDLING CYLINDERS
Work Hygienic Practices:OBSERVE GOOD INDUSTRIAL HYGIENE PRACTICES AND
    RECOMMENDED PROCEDURES.
