LD50 LC50 Mixture:NONE SPECIFIED BY MANUFACTURER.
Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:BREATHING MIXTURES WITH LOW (18 MOLAR
%) OXYGEN CONCENTRATIONS AT ATMOSPHERIC PRESSURE CAUSE DIZZINESS,
DEEPER BREATHING DUE TO AIR HUNGER, POSSIBLE NAUSEA AND EVENTUAL
UNCONSCIOUSNESS. BREATHING MIXT URES OF HELIUM WITH ADEQUATE OXYGEN
TO SUPPORT LIFE MODIFIES THE VOICE SOUND SO THAT IT IS HIGHER (EFTS
OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZS:PITCHED. TOX PROPERTIES:MIXTURES WITH
LESS THAN 18 MOLAR % OXYGEN ARE INACTIVE BIOLOGICALLY AND
ESSENTIALLY NONTOXIC; THEREFORE, THE MAJOR PROPERTY IS THE
EXCLUSION OF AN ADEQUATE SUPPLY OF OXYGEN TO THE LUNGS.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

First Aid:PROMPT MED ATTN IS MANDATORY IN ALL CASES OF OVEREXP TO MIXS
CNTNG < 18 MOLAR % OXYG. RESCUE PERS SHOULD BE EQUIPPED
W/NIOSH/MSHA APPRVD SCBA. INGEST:CALL MD IMMED . EYES:IMMED FLUSH
W/POTABLE W ATER FOR MIN OF 15 MIN, SEEK ASSISTANCEFROM MD .
SKIN:FLUSH W/COPIOUS AMTS OF WATER. CALL MD . INHAL:CONSCIOUS
PERSONS SHOULD BE ASSISTED TO UNCONTAM AREA & INHAL FRESH AIR.
QUICK(SUPDAT)

Extinguishing Media:MEDIA SUITABLE FOR SURROUNDING FIRE . NONFLAMMABLE,
INERT GAS.
Fire Fighting Procedures:WEAR NIOSH/MSHA APPROVED SCBA & FULL
PROTECTIVE EQUIPMENT .
Unusual Fire/Explosion Hazard:NOT APPLICABLE.

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
APPROPRIATE PROTECTIVE EQUIPMENT. IF LEAK IS IN CONTAINER OR
CONTAINER VALVE, CONTACT CHEMTREC FOR EMERGENCY ASSISTANCE OR YOUR
CLOSEST MANUFACTURER LOCA TION.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:USE ONLY IN WELL-VENT AREAS. VALVE
PROT CAPS MUST REMAIN IN PLACE UNLESS CNTNR IS SECURED W/VALVE
OUTLET PIPED TO USE POINT.
Other Precautions:DO NOT DRAG, SLIDE/ROLL CYLS. USE SUITABLE HAND TRUCK
FOR CYL MOVEMENT. USE PRESS REDUCING REGULATOR WHEN CONNECTING CYL
TO LOWER PRESS (<3,000 PSIG) PIPING/SYS. DO NOT HEAT CYL BY ANY
MEANS TO INCREA SE DISCHARGE RATE/PROD FROM CYL. (ING 3)

Respiratory Protection:NIOSH/MSHA APPROVED POSITIVE PRESSURE AIR LINE
WITH MASK OR NIOSH/MSHA APPROVED SELF-CONTAINED BREATHING APPARATUS
SHOULD BE AVAILABLE FOR EMERGENCY USE.
Ventilation:LOCAL EXHAUST;TO PREVENT ACCUMULATION OF HIGH
CONCENTRATIONS SO AS TO REDUCE THE OXYGEN LEVEL IN AIR TO < 18
MOLAR %.
Protective Gloves:IMPERVIOUS GLOVES .
Eye Protection:ANSI APPROVED CHEM WORKERS GOGGS .
Other Protective Equipment:ANSI APPROVED EMERGENCY EYE WASH AND DELUGE
SHOWER . SAFETY SHOES.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
Supplemental Safety and Health
SPEC GRAV:0.35 @ 70F, 1 ATM (AIR=1). FIRST AID PROC:REMOVAL FROM CONTAM
AREA IS MOST IMPORTANT. UNCON PERSONS SHOULD BE MOVED TO AN
UNCONTAM AREA, GIVEN MOUTH-TO-MOUTH RESUSCITATION & SUPP OXYG.
FURTH ER TREATMENT SHOULD BE SYMPTOMATIC & SUPPORTIVE.
