HAZARDOUS COMPONENTS



Material(s):                                         Approximate weight % :

Isobutane (R-600a)                                   4

chlorodifluoroethane (R-142b)                        15

heptafluoropropane (R-227ea)                         40

chlorodifluoromethane (R-22)                         41





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.



Heptafluoropropane.

Immediate (acute) effects:

        Acute Inhalation.....4HR LC50 (rat) > 788,696 ppm

        Cardiac Senaitization Threshold....NOAEL 90,000 ppm, LOAEL 105,000 ppm (dog)

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.

REGULATORY INFORMATION



1,1,1,2,3,3,3-heptafluoropropane falls under the Significant New Use Rule (SNUR) (40 CFR 721.8125)



1. The SNUR applies to any person (company) who intends to manufacture, import, or process the

product (heptafluoropropane component) for commercial purposes.



2. SNUR recordkeeping

       The following records must be maintained for five years following their date of creation:



         a. Records documenting the dates and volumes of manufacture or import.



         b. Records documenting the volumes of the substance purchased in the United States, the dates

            of purchase, and the names and addresses of suppliers.



         c. Records documenting the names and addresses of all persons to whom the manufacturer,

            importer, or processor sells or transfers the substance, and the date and volume of each sale

            or transfer.



         d. Records documenting compliance with any use restrictions.

3. SNUR use restrictions



        The product may not be used in aerosol products intended for consumer use. This restriction

        does not apply to the use of the substance in fire extinguishing apparatus or systems.





This entire mixture of components, is also subject to to the EPA SNAP rules and regulations when used

to replace an ozone depleting substance (such as Refrigerant-12) and the Clean Air Act of 1990, as

ammended.

.



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, 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.
