Routes of Entry: Inhalation:YES Skin:YES Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:ACUTE: THE MOST SIGNIFICANT HAZ ASSOC
W/THIS GAS IS INHAL OF OXYGEN-DEFICIENT ATMOSPHERES. INDIVIDUALS
BRTHG SUCH ATM MAY EXPERIENCE SYMPS WHICH INCL HDCHS, RINGING IN
EARS, DIZZ, DROW, UNCON, NAUS, V OMIT & DEPRESS OF ALL SENSES. SKIN
OF VICTIM MAY HAVE A BLUE COLOR. UNDER SOME CIRCUMSTANCES, DEATH
MAY OCCUR. EFTS ASSOC W/VARIOUS LEVELS OF OXYGEN ARE AS FOLLOWS:
12-16% OXYGEN: BRTHG & PULSE RATE I NCREASED, MUSC COORD SLIGHTLY
DISTURBED. 10-14% OXYGEN: EMOTIONAL UPSET, ABDOMINAL FATG,
DISTURBED RESPIRATION. 6-10% OXYGEN: NAUS & VOMITING, COLLAPSE OR

Medical Cond Aggravated by Exposure:PRE-EXISTING RESPIRATORY CONDITIONS
MAY BE AGGRAVATED BY OVEREXPOSURE TO HELIUM.
======================= First Aid Measures =======================
First Aid:INGEST:CALL MD IMMED . RESCUERS SHOULD NOT ATTEMPT TO
RETRIEVE VICTIMS OF EXPOS TO HELIUM W/OUT ADEQ PPE. AT MIN, WEAR
NIOSH APPRVD SCBA. REMOVE TO FRESH AIR AS QUICKLY AS POSS. EYES:IN
CASE OF CNTCT, IMMED FLUSH EYES W/COPIOUS AMTS OF WATER FOR AT LST
15 MIN. INHAL:IF BRTHG DFCLT, GIVE OXYG. ONLY TRAINED PERS SHOULD
ADMIN SUPPLEMENTAL OXYG. SKIN:IN CASE OF FROSTBITE, PLACE
FROSTBITTEN PART IN WARM WATER. DO NOT USE HOT WATER. IF WARM
WATER IS NOT AVAIL/IS IMPRACTICAL, WRAP AFFECTED PARTS GENTLY IN
BLANKETS. ALTERNATIVELY, IF FINGERS OR HANDS ARE FROSTBITTEN PLACE
AFFECTED AREA IN ARMPIT . ENCOURAGE VICTIM TO GENTLY (SUPDAT)
===================== Fire Fighting Measures =====================
Extinguishing Media:NON-FLAMMABLE, INERT GAS. USE EXTINGUISHING MEDIA
APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:USE NIOSH APPRVD SCBA & FULL PROT EQUIP . MOVE
FIRE-EXPOSED CYLINDERS IF IT CAN BE DONE W/OUT RISK TO
FIREFIGHTERS. OTHERWISE, COOL CNTNRS W/HOSE STREAM & PROTECT
PERSONNEL. W/DRAW IMMEDIATELY I N CASE OF RISING SOUNDS FROM
VENTING SAFETY DEVICE OR ANY DISCOLORATION OF TANKS DUE TO THE
FIRE.
Unusual Fire/Explosion Hazard:HELIUM DOES NOT BURN; HOWEVER, CNTNRS,
WHEN INVOLVED IN FIRE, MAY RUPTURE OR BURST IN HEAT OF
FIRE.EXPLOSION SENSITIVITY TO MECHANICAL IMPACT/STATIC DISCHARGE:
NOT SENSITIVE. NFPA RATING - HELIUM GAS: FLAMMABILITY: 0; HEALTH:
1; REACTIVITY: 0.
================== Accidental Release Measures ==================
Spill Release Procedures:UNCONTROLLED RELS SHOULD BE RESPONDED TO BY
TRAINED PERS USING PRE-PLANNED PROCS. PROPER PROT EQUIP SHOULD BE
USED. IN CASE OF RELS, CLEAR AFFECTED AREA & PROTECT PEOPLE. MIN
PPE SHOULD BE LEVEL B: PR OT CLTHG, GLOVES RESIST TO TEARS & NIOSH
APPRVD SCBA. ALLOW GAS, WHICH IS HVR/AIR, TO DISSIPATE. MONITOR
SURROUNDING AREA FOR OXYG LEVELS. ATM MUST HAVE AT LST 19.5% OXYG
BEFORE PERS CAN (OTHER INFO)
====================== Handling and Storage ======================
Handling and Storage Precautions:CYLINDERS SHOULD BE STORED IN DRY,
WELL-VENTILATED AREAS AWAY FORM SOURCES OF HEAT. COMPRESSED GASES
CAN PRESENT SIGNIFICANT SAFETY HAZS. STORE CONTAINERS AWAY FROM
HEAVILY TRAFFICKED AREAS AND EMERGE NCY EXIST. POST "NO SMOKING OR
OPEN FLAMES" SIGNS IN STORAGE OR USE AREAS.
Other Precautions:SPEC PRECS FOR HNDLG GAS CYLS: PROTECT AGAINST
PHYSICAL DMG. STORE IN COOL, DRY, WELL-VENTD FIREPROOF AREA, AWAY
FROM FLAM MATLS & CORR ATMS. STORE AWAY FROM HEAT & IGNIT SOURCES &
OUT OF DIRECT SUN. DO NOT STORE NEAR ELEVATORS, CORRIDORS/LOADING
DOCKS. DO NOT ALLOW AREA WHERE STORED TO EXCEED 52C(1 25F). (OTHER
INFO)
============= Exposure Controls/Personal Protection =============
Respiratory Protection:MAINTAIN OXYGEN LEVEL ABOVE 19.5% IN WORKPLACE.
USE NIOSH APPRVD SUPPLIED AIR RESP PROT IF OXYGEN LEVEL IS BELOW
19.5% OR DURING EMER RESPONSE TO RELEASE OF HELIUM. IF RESP PROT IS
REQD, FOLLOW REQS O F FEDERAL OSHA RESP PROT STANDARD (29 CFR
1910.134) OR EQUIVALENT STATE STANDARDS.
Ventilation:USE W/ADEQ VENT TO MAINTAIN OXYG LEVEL ABOVE 19.5% IN WORK
AREA. LOC EXHST VENT IS PREF BECAUSE IT PVNTS HELIUM DISPERSION

Eye Protection:ANSI APPROVED CHEMICAL WORKERS GOGGLES & FULL LENGTH
FACESHIELD .
Other Protective Equipment:ANSI APPRVD EYE WASH & DELUGE SHOWER . BODY
PROT APPROP FOR TASK. TRANSFER OF LG QTYS UNDER PRESS MAY REQ EQUIP
APPROP TO PROTECT FROM SPLASHES OF LIQUEFIED PROD & INSULATION FROM
EXTREME COLD.
Work Hygienic Practices:AS W/ALL CHEMS, AVOID GETTING HELIUM IN YOU. DO
NOT EAT/DRINK WHILE HNDLG CHEMS. BE AWARE OF ANY SIGNS OF DIZZ OR
