Health Hazards Acute and Chronic:INHAL: PREDOMINANT HZD IS ASPHYXIA.
MAT'L IS LOW IN TOXICITY AT CONCENTRATIONS AS HIGH AS 4%. WHEN
OXYGEN LEVELS IN AIR ARE REDUCED TO 12-14% SYMPTOMS OF ASPHYXIATION
WILL OCCUR. SKIN: CONTACT W/LIQUI D MAT'L CAN CAUSE FROSTBITE,
INDICATED BY PALLOR OR REDNESS, LOSS OF SENSATION AND SWELLING.
EYES: SAME AS FOR SKIN. *
Effects of Overexposure:INHALATION: LOSS OF COORDINATION, INCREASED
PULSE RATE, CARDIAC SENSITIZATION AND DEEPER RESPIRATIONS ARE
POSSIBLE. *NARCOTIC EFFECT REPORTED.
CARDIAC ARRHYTHMIA & MYOCAR DIAL DEPRESSION SEEN IN ANIMAL
STUDIES.THIS PRODUCT CAN CAUSE DEATH OR SERIOUS PERSONAL INJURY IF
NOT HANDLED PROPERLY.
Medical Cond Aggravated by Exposure:WORKERS WITH CARDIOVASCULAR OR
PULMONARY PROBLEMS SHOULD HAVE MEDICAL EVALUATION BEFORE EXPOSURE.

First Aid:INHAL: REMOVE IMMED TO FRESH AIR. IF BREATHING HAS STOPPED,
GIVE ARTIF RESPIRATION, PREFERABLY MOUTH-TO-MOUTH. USE OXYGEN AS
REQUIRED, IF QUALIFIED OPERATOR IS AVAILABLE. DON'T GIVE
EPINEPHRINE (ADREN ALIN). SKIN/EYE CONTACT: IMMED BATHE FROSTBITE
(DO NOT RUB) WITH LUKEWARM (NOT HOT) WATER. IN ABSENCE OF WATER
COVER WITH SOFT WOOL, ETC. CONTACT DR FOR ANY LOW TEMPERATURE BURNS
FROM LIQ CONTACT.

Extinguishing Media:ANY STANDARD AGENT--CHOOSE THE ONE THAT IS
APPROPRIATE FOR TYPE OF FIRE. MATERIAL ITSELF IS NON-FLAMMABLE.
Fire Fighting Procedures:WEAR SELF-CONTAINED NIOSH BREATHING APPARATUS
FOR PROTECTION AGAINST SUFFOCATION & POSSIBLE TOXIC DECOMP
PRODUCTS. USE WATER SPRAY TO COOL FIRE EXPOSED CNTNRS.
Unusual Fire/Explosion Hazard:MAT'L LIQ & GAS UNDER OWN VAPOR PRESSURE.
NOT COMBUST, CONTACT W/SOME METALS MAY PRODUCE EXOTHERMIC
REACTION/POTENTIALLY EXPLOS COMBINATIONS. SEE HAZARD DECOMP.

Spill Release Procedures:USING SELF-CONTAINED AIR SUPPLY & PROTECTION
AGAINST FROSTBITE, PERSONNEL SHOULD ATTEMPT TO CLOSE VALVES OR
REPAIR SOURCE OF LEAK. IF LARGE QUANTITY IS RELEASED, EVACUATE
PERSONNEL AND ALLOW TO DISSIP ATE.

Handling and Storage Precautions:AVOID EYE/SKIN/CLOTHING CONTACT. DON'T
PUNCTURE/DROP CYLINDERS/EXPOSE TO FLAME/HEAT. USE AUTHORIZED
CNTNRS. FOLLOW STD SFTY PRECAUTION FOR COMPRSD GAS
Other Precautions:STORE IN COOL, DRY, VENTED AREA AWAY FROM
HEAT/FLAME/COMBUSTIBLES. PROTECT CYLINDER & FITTINGS FROM DAMAGE.
AVOID STORAGE IN SUBSURFACE LOCATIONS. FOLLOW OSHA REGULATIONS FOR
COMPRESSED GAS & FOR CYLI NDER HANDLING.

Respiratory Protection:NONE GENERALLY REQUIRED FOR ADEQUATELY VENTED
SITUATIONS. FOR UNUSUAL SITUATIONS, WEAR A NIOSH APPROVED, SUPPLIED

APPARATUS.
Ventilation:PROVIDE LOCAL EXHAUST AT FILLING ZONES/AREA LEAK LIKELY.
MECHAN(GEN) VENT FOR OTHER OPERATING/STORAGE AREAS.
Protective Gloves:IMPERVIOUS GLOVES W/PVA OUTER LAYER **
Eye Protection:CHEM SAFETY GOGGLES IF CONTACT ***
Other Protective Equipment:WEAR IMPERVIOUS SHOES & CLOTHING WHERE
LEAKAGE IS PROBABLE. GLOVES, CLOTHING, SHOES SHOULD BE THERMALLY
INSULATED.
Work Hygienic Practices:PROVIDE WATER SOURCE FOR FIRST AID TREATMENT
(FROSTBITE). ** (NEOPRENE-2ND CHOICE) IF HANDLING/LEAKAGE
POSSIBLE.
Supplemental Safety and Health
*** IS REASONABLE PROBABILITY. IN THIS CASE, DON'T WEAR CONTACT LENSES.
DON'T CONSIDER
MAT'L INERT. HIGH CONC IN AIR (20X TLV) HAVE BEEN SHOWN TO REDU CE
VENT CAPACITY OF LUNGS TEMPORARILY &TO PRODUCE MINOR CARDIAC
EFFECTS (INCREASED BY EPINEPHRINE).
