HAZARDOUS COMPONENTS
--------------------
Material(s): Approximate weight % :
Isobutane (R-600a) 4
chlorodifluoroethane (R-142b) 16.5
chlorotetrafluoroethane 28.5
chlorodifluoromethane (R-22) 51
HAZARDOUS REACTIVITY
--------------------
Stability:
Material is stable. However, avoid open flames and high temperatures.
Incompatibility (materials to avoid):
Strong oxidants, including oxygen.
Freshly scraped aluminum, Alkali metals, and Alkali earth metals
(sodium, magnesium, etc), may cause exothermic reaction. Aluminum
in refrigeration systems contains an oxide/chloride coating, so
it does not react.
Hazardous decomposition products:
May decompose at high temperatures (above 400F - 500F), and from
contact with hot metal, heating elements, pilot lights, internal
combustion engines, and open flames. Decomposition products may
include hydrofluoric and hydrochloric acids, chlorine, fluorine,
possibly phosgene and carbonyl halids, carbon dioxide, and carbon
monoxide.
Polymerization:
Will not occur.
FIRE AND EXPLOSION DATA:
-----------------------
Flash Point:
NONE
Autoignition temperature:
about 500C
Autodecomposition Temperature:
400F or higher
Fire and Explosion:
Product is nonflammable, both as formulated, and after worst case
vapor leakage (fractionation). Cylinders of product recovered from
refrigeration systems, may contain mineral oil and may be flammable
due to dissolved oils.
Cylinders may vent or rupture in fire conditions, leading to
decomposition.
Extinguishing Media:
Water spray.
Special Fire Fighting Instructions:
Use self-contained breathing apparatus. Use water spray to cool
cylinders to prevent bursting or venting under fire conditions.
Product may be flammable if mixed with large quantities of air at
greater than atmospheric pressure.
Cylinders of USED refrigerant, may contain large amounts of refrigeration
(mineral) oil. A liquid leak or cylinder venting in a fire will bring
out a cloud of oil mist. This oil mist can be very flammable (in the
order of gasoline).
HEALTH HAZARD INFORMATION
-------------------------
Principle Health Hazards:
Inhalation: Vapor is heavier than air and can cause suffocation by
displacing oxygen available for breathing. Contact with liquid may
cause frostbite.
Breathing high concentrations of vapor may cause light headedness,
giddiness, shortness of breath, and may lead to narcosis, cardiac
irregularities, unconsciousness or death. May cause eye irritation.
Toxicity / Exposure limits:
OSHA and ACGIH Not established, but reccommend TWA 1000 PPM.
Isobutane.
Humans exposed to Isobutane, 500 PPM, 8 hours/day, 5 days/week, for
4 weeks, showed no cardiac, pulmonary or other functional abnormalities.
Chlorodifluoroethane.
Inhalation - Rat - 4 HR LC50 = 128,000 PPM.
Chlorodifluoromethane.
Low in toxicity at concentrations as high as 4% (40,000 ppm). Narcotic
effects have been seen at 200,000 ppm. Heart effeciency (animal studies)
has been reported to be reduced at concentrations of over 25,000 ppm.
Cardiac sensitization to epinephrine has been observed at concentrations
of 50,000 ppm.
Chlorotetrafluoroethane.
Immediate (acute) effects:
Acute Inhalation.....4HR LC50 (rat) - 360,000 ppm
Cardiac Senaitization Threshold....25,000 ppm (dog)
Central Nervous System Depression....10-min EC50 = 140,000 ppm
Delayed (subchronic & chronic) effects:
Subchronic inhalation: NOEL (rat and mouse) ....15,000 ppm
other data:
Teratology - (rat and mouse-dams)....NOEL.....15,000 ppm
NOEL (pups) ...30,000 ppm
First Aid
---------
Inhalation: Remove to fresh air, call a physician. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Do not give epinephrine or similar drugs.
Note to physicians: Because of possible increased risk or eliciting
cardiac dysrythmias, catecholamine drugs, such as epinephrine, should be
considered only as a last resort in life threating emergencies.
Eyes: Flush immediately with water for at least 15 minutes. Call a
physician.
Skin: Flush with water, warm slowly (cool water) if frostbite. Call a
physician.
PRECAUTIONS/PROCEDURES
----------------------
Spill or leak:
Using a self-contained air supply and frostbite protection, personnel
should attempt to close valves or repair the source of the leak, if it
is safely possible to do so. If a large quantity is released, evacuate
personnel, and allow to dissipate.
SHIPPING INFORMATION
--------------------
Proper shipping name: Compressed Gas, N.O.S UN1956
DOT placard: Nonflammable gas

REGULATORY INFORMATION
----------------------
Toxic Substances Control Act (TSCAL)
ISCA Inventory Stature: R-124 is on the TSCA inventory
Other TSCA Issues:
It is subject to SNUR publ in the Federal Register of July 22, 1992
at 57FR3241.
WARNING: DO NOT VENT to the atmosphere. To comply with provisions of
the US Clean Air Act, any residual must be recovered.
CONTAINS HCFC-22 and HCFC-142b and HCFC-124, substances which harm
public health and environment by destroying ozone in the upper
atmosphere. Destruction of the ozone layer can lead to increased
ultraviolet radiation which, with excess exposure to sunlight, can lead
to an increase in skin cancer and eye cataracts.
