3. Hazards Identification
EMERGENCY OVERVIEW
This product does not contain oxygen and may cause asphyxia if released in a confined area.
Chlorofluorocarbons can cause irritation, central nervous system depression and irregular heart beat
at high concentrations. Nonflammable but decomposes to toxic gases, including phosgene, under fire
conditions.

No No No
Synergistic Effects
None Reported
Carcinogenicity: -- NTP: No IARC: No OSHA: No
EYE EFFECTS:
PERSONS WITH POTENTIAL EXPOSURE SHOULD NOT WEAR CONTACT LENSES.
SKIN EFFECTS:
None anticipated as product is a gas at room temperature.
INGESTION EFFECTS:
Ingestion is not likely.
INHALATION EFFECTS:
Product is relatively nontoxic. CFCs can irritate the eyes, mucous membranes and respiratory system.
Inhalation of high concentrations may cause dizziness, disorientation, incoordination, narcosis, nausea or
vomiting leading to unconsciousness. At high concentrations narcotic effects may be produced and may cause
the heart to beat irregularly and stop.
Experimental studies have noted reproductive toxicity in male rats from inhalation exposure at high
concentrations.
Mutations were produced in a bacterial assay system.
Oxygen deficiency may occur in the presence of high concentrations resulting in asphyxiation. Maintain oxygen
levels above 19.5% at sea level.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Pre-existing heart conditions.

4. First Aid Measures
EYES:
Never introduce ointment or oil into the eyes without medical advice! If pain is present, refer the victim to an
opthalmologist for treatment and follow up.
MSDS: G-46
Revised: 6/7/96 Page 2 of 7
PRODUCT NAME: HALOCARBON 22
SKIN:
Remove contaminated clothing and flush affected areas with lukewarm water. If irritation persists, seek medical
attention.
INGESTION:
Unlikely as product is a gas at room temperature.
INHALATION:
PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE. RESCUE
PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS. Remove
victim to fresh air. Administer artificial respiration if breathing has stopped and supplement with oxygen by a
trained individual. Further treatment should be symptomatic and supportive. Seek medical attention as soon as
possible for follow up treatment. Remove to fresh air. If necessary, give oxygen or provide artificial
respiration. Call a physician.
NOTE TO PHYSICIAN: A patient adversely affected by exposure to this product should not be given adrenalin
(epinephrine) or similar heart stimulant since these would increase the risk of cardiac arrhythmias.
5. Fire Fighting Measures
Conditions of Flammability: Nonflammable
Flash point: Method: Autoignition
None Not Applicable Temperature: None
LEL(%): None UEL(%): None
Hazardous combustion products: None. Decomposes to toxic gases at fire temperatures
Sensitivity to mechanical shock: None
Sensitivity to static discharge: None
FIRE AND EXPLOSION HAZARDS:
If involved in a fire, product may decompose yielding toxic products, which may include phosgene, hydrochloric
and hydrofluoric acids.
EXTINGUISHING MEDIA:
None required. Use media appropriate for surrounding flammable substances.
FIRE FIGHTING INSTRUCTIONS:
Positive-pressure, self-contained respiratory equipment for fires involving large quantities of this material.
6. Accidental Release Measures
Evacuate all personnel from affected area. Use appropriate protective equipment. If leak is in user鈥檚 equipment,
be certain to purge piping with inert gas prior to attempting repairs. If leak is in container or container valve,
contact the appropriate emergency telephone number listed in Section 1 or call your closest BOC location.

PRODUCT NAME: HALOCARBON 22
7. Handling and Storage
Product is noncorrosive and may be used with any common structural material. Silver and carbon bearing alloys
can act as catalysts for decomposing the product at high temperatures. Alloys containing more than 2%
magnesium should not be used if water is present.
Use only in well-ventilated areas. Valve protection caps must remain in place unless container is secured with
valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder
movement. Use a pressure reducing regulator when connecting cylinder to lower pressure (<200 psig) piping or
systems. Do not heat cylinder by any means to increase the discharge rate of product from the cylinder. Use a
check valve or trap in the discharge line to prevent hazardous back flow into the cylinder. Protect cylinders
from physical damage.
Store in cool, dry, well-ventilated area of non-combustible construction away from heavily trafficked areas and
emergency exits. Do not allow the temperature where cylinders are stored to exceed 125oF (52oC). Cylinders
should be stored upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders
should be segregated. Use a "first in-first out" inventory system to prevent full cylinders being stored for
excessive periods of time. For additional handling recommendations, consult Compressed Gas Association
Pamphlet P-1. Handle with reasonable care. Store in a cool, dry place.
Never carry a compressed gas cylinder or a container of a gas in cryogenic liquid form in an enclosed space such
as a car trunk, van or station wagon. A leak can result in a fire, explosion, asphyxiation or a toxic exposure.
