Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:HYDROGEN IN ARGON GAS MIXTURE IS
SIMPLE ASPHYXIANT. HIGH CONCENTRATIONS OF THIS GAS MIXTURE WHICH
EXCLUDE ADEQUATE SUPPLY OF OXYGEN FROM LUNGS CAUSES DIZZINESS,
DEEPER BREATHING DUE TO AIR HUNGER (ANO XIA), POSSIBLE NAUSEA &
EVENTUAL UNCONSCIOUSNESS. HYDROGEN & ARGON ARE RELATIVELY INACTIVE
(EFTS OF OVEREXP)
Explanation of Carcinogenicity:NOT RELEVANT
Effects of Overexposure:HLTH HAZ:BIOLOGICALLY & ESSENTIALLY NONTOXIC;
THEREFORE, THE MAJOR HAZARD IS THE EXCLUSION OF AN ADEQUATE SUPPLY
OF OXYGEN TO THE LUNGS.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

First Aid:INGEST:CALL MD IMMED. EYES:IMMED FLUSH W/POTABLE WATER FOR
MINIMUM OF 15 MIN, SEEK ASSISTANCE FROM MD. SKIN: FLUSH W/COPIOUS

RESUSCITATION. FURTHER TREATMENT SHOULD BE SYMPTOMATIC & (SUPDAT

Lower Limits:4% (H2)
Upper Limits:74.5% (H2)
Extinguishing Media:USE EXTING MEDIA SUITABLE FOR COMBUSTIBLE MATLS
INVOLVED IN THE FIRE. USE WATER SPRAY TO COOL FIRE EXPOSED
CONTAINERS.
Fire Fighting Procedures:USE NIOSH/MSHA APPRVD SCBA & FULL PROT EQUIP.
IF POSS, STOP FLOW OF GAS MIX. HYDROGEN BURNS W/ALMOST INVISIBLE
FLAME OF RELATIVELY LOW THERMAL (SUPDAT)
Unusual Fire/Explosion Hazard:HYDROGEN IS VERY LIGHT & RISES VERY
RAPIDLY IN AIR. SHOULD HYDROGEN GAS MIX FIRE BE EXTING & FLOW OF
GAS CONTINUE, INCR VENT TO PVNT EXPLO HAZ, ESP IN (SUPDAT)

Spill Release Procedures:EVACUATE ALL PERS FROM AFFECTED AREA. USE
APPROP PROT EQUIP. IF LEAK IS IN USER'S EQUIP, BE CERTAIN TO PURGE
PIPING W/INERT GAS PRIOR TO ATTEMPTING REPAIRS. IF LEAK IS IN
CNTNR/CNTNR VALVE, CNTCT CHEM TREC FOR EMER ASSISTANCE OR YOUR
CLOSEST MFR.
