LD50 LC50 Mixture:INH RAT LC50: 35 PPH/15M
Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:INHALATION: THIS MATERIAL IS LOW
TOXICITY AT CONCENTRATIONS AS HIGH AS 4%. WHEN OXYGEN LEVELS ARE
REDUCED TO 12-14%, SYMPTOMS OF ASPHYXIATION WILL OCCUR. NARCOTIC
EFFECTS HAVE BEEN SEEN AT 20%. CONTAC T WITH LIQUID OR ESCAPING
VAPOR CAN CAUSE FROSTBITE, INDICATED BY PALLOR OR REDNESS, LOSS OF
SENSATION AND SWELLING.
Explanation of Carcinogenicity:THIS PRODUCT IS NOT LISTED BY IARC, NTP
OR OSHA AS A CARCINOGEN, MUTAGEN, TERATOGEN OR NEUROTOXIN.
Effects of Overexposure:INHALATION: WHEN OXYGEN LEVELS ARE REDUCED TO
12-14%, LOSS OF COORDINATION, INCREASED PULSE RATE, AND DEEPER
RESPIRATION. FROSTBITE IS INDICATED BY PALLOR OR REDNESS, LOSS OF
SENSATION AND SWELLING.
Medical Cond Aggravated by Exposure:PERSONS WITH HEART DISEASE MAY BE
AT INCREASED RISK WHEN EXPOSED TO THIS MATERIAL.

First Aid:INHALATION: REMOVE IMMEDIATELY TO FRESH AIR. IF BREATHING HAS
STOPPED, GIVE ARTIFICIAL RESPIRATION, PREFERABLY MOUTH-TO-MOUTH.
USE OXYGEN AS REQUIRED. DO NOT GIVE EPINEPHRINE(ADRENALINE). SKIN
OR EYE CONTACT: IMMEDIATELY BATHE (DO NOT RUB)ANY FROSTBITE WITH
LUKEWARM (NOT HOT) WATER. IN THE ABSENCE OF WATER, COVER WITH SOFT
WOOL OR OTHER SUITABLE MATERIAL. GET MEDICAL ATTENTION FOR LOW TEMP
BURNS.

Flash Point:NONFLAMMABLE
Autoignition Temp:Autoignition Temp Text:NONE
Extinguishing Media:ANY STANDARD AGENT--CHOOSE THE ONE MOST SUITABLE
FOR SURROUNDING FIRE. THIS MATERIAL IS NOT FLAMMABLE.
Fire Fighting Procedures:ALTHOUGH NOT FLAMMABLE, WHEN THIS MATERIAL IS
IN A FIRE, FIREFIGHTERS SHOULD WEAR SELF-CONTAINED BREATHING
APPARATUS FOR PROTECTION AGAINST SUFFOCATION/FUMES.
Unusual Fire/Explosion Hazard:WHILE NOT COMBUSTIBLE ITSELF, CONTACT
WITH CERTAIN METALS AND OXIDIZING MATERIALS MAY PRODUCE EXOTHERMIC
REACTIONS OR POTENTIAL EXPLOSIVE COMBINATIONS.

Spill Release Procedures:USING A SELF-CONTAINED AIR SUPPLY AND
PROTECTION AGAINST FROSTBITE, PERSONNEL SHOULD ATTEMPT TO CLOSE
VALVES OR REPAIR SOURCE OF LEAK IF WITHOUT RISK. IF A LARGE
QUANTITY IS RELEASED, EVACUATE PERSONN EL AND ALLOW TO DISSIPATE.
Neutralizing Agent:NONE

Handling and Storage Precautions:DO NOT BREATHE GAS; AVOID CONTACT WITH
EYES, SKIN AND CLOTHING. DO NOT PUNCTURE OR DROP CYLINDERS OR EXOSE
THEM TO OPEN FLAME OR EXCESSIVE HEAT.
Other Precautions:USE AUTHORIZED CONTAINERS ONLY. STORE IN COOL, DRY,
WELL-VENTILATED AREA AWAY FROM HEAT, FLAME OR COMBUSTIBLES. PROTECT
CYLINDERS AND FITTINGS FROM PHYSICAL DAMAGE. STORAGE IN SUBSURFACE
LOCATIONS SHO ULD BE AVOIDED.

Respiratory Protection:NONE GENERALLY REQUIRED FOR NORMALLY VENTED
SITUATIONS. OTHERWISE, WEAR A NIOSH APPROVED SUPPLIED AIR
RESPIRATOR OR SELF-CONTAINED BREATHING APPARATUS. AT HIGH
CONCENTRATIONS, ADD A FULL FACEPIECE.
Ventilation:VENTILATION SHOULD BE ADEQUATE TO MEET TLV REQUIREMENTS AND
MINIMIZE EXPOSURE SHOULD MATERIAL BE RELEASED.
Protective Gloves:PVA, NEOPRENE
Eye Protection:CHEMICAL SAFETY GOGGLES.
Other Protective Equipment:IMPERVIOUS SHOES AND CLOTHING, THERMALLY
INSULATED. PROVIDE CONVENIENT WATER SOURCE FOR FIRST AID TREATMENT
FOR FROSTBIT
Work Hygienic Practices:DO NOT WEAR CONTACT LENSES.
Supplemental Safety and Health
PROVIDE LOCAL EXHAUST AT FILLING ZONES AND WHERE LEAKAGE IS PROBABLE.
MECHANICAL (GENERAL) VENTILATION IS ADEQUATE FOR OTHER OPERATING
AREAS AND FOR STORAGE AREAS.
