SECTION I - MATERIAL IDENTIFICATION AND INFORMATION
Hazardous Components - Specific Chemical Identity & Common Names
OSHA PEL ACGIH TLV %
1,1-Dichloro-1-Fluoroethane 500 p.p.m. 500 p.p.m. 60-65%
(HCFC-141b CAS# 1717-00-6)
(1, 1-Dichloro-1-fluoroethane is listed only because its vapors are heavier than
air and will displace normal breathing air.)
1,1,1,2 - Tetrafluoroethane not listed not assigned 35-30%
(HFC-134a CAS# 811-97-2)
(1,1,1,2 - Tetrafluoroethane is listed here because it is a compressed liquified gas.)
SECTION 2 - PHYSICAL / CHEMICAL CHARACTERISTICS
Boiling Point: 89.7癋
Vapor Pressure
(mm Hg and Temperature): @70癋 = 2.5 psig @ 21.1癈 = 2430.6 mm Hg
Vapor Density ( Air = 1 ): 4.17
Melting Point: Less than -60癋
Evaporation Rate (Butyl Acetate = 1 ): Not available
Solubility In Water: Insoluble
Specific Gravity ( H2O = 1 ): 1.23
Appearance and Odor: Clear, colorless liquid with faint ethereal odor.
SECTION 3 - FIRE AND EXPLOSION HAZARD DATA
Flash Point and Method Used: Not tested but expect none. Individual components
show NONE in open cup test.
Flammability Limits: Not available
LEL: N/A UEL: N/A
Extinguisher Media: CO2; water fog. Liquid concentrate not expected to support
combustion.
Unusual Fire and Explosion Hazards: Floor will be slippery where materials are
released. Toxic vapors may be formed from combustion. Vapors will accumulate rapidly
in poorly ventilated, confined or low-lying areas and displace air. Contact with certain
finely divided reactive metals may cause reactions. Decomposition products may be
hazardous.
Special Fire Fighting procedures: Fire fighters should wear self-contained, NIOSH-
approved breathing apparatus for protection against possible toxic decomposition
products. Proper eye and skin protection should also be provided. Use water spray to
keep fire-exposed containers cool and to suppress vapors.
SECTION 4 - REACTIVITY HAZARD DATA
Stability: Stable
Conditions To Avoid: Any source of ignition, such as lighted cigarettes, flame, hot
spots, welding. Nonexplosive conditions may yield toxic and/or corrosive decomposition
products. (HCFC-141b will decompose to hydrogen chloride, hydrogen fluoride and
possibly carbonyl halides.)
Incompatibility (Materials to Avoid): Under specific conditions: e.g., very high
temperatures and/or appropriate pressures. Freshly abraded aluminum surfaces may
cause strong exothermic reaction. Chemically active metals: sodium, potassium,
calcium, powdered aluminum, magnesium and zinc.
Hazardous Decomposition or By-products: Halogens, halogen acids, and possibly
carbonyl halides, such as phosgene. These are toxic and corrosive.
HAZARDOUS POLYMERIZATION: Will Not Occur
Conditions to Avoid: None known
SECTION 5 - HEALTH HAZARD DATA
PRIMARY ROUTES OF ENTRY:
Inhalation: Yes Skin: Yes Ingestion: Yes (not likely in acutely toxic
quantities)
HEALTH HAZARDS: Can contents are a defatting agent. Repeated or prolonged
contact with liquid may dry mucous membranes and defat the skin causing dermatitis.
Carcinogenicity:
NTP? Not found IARC Monographs? Not found OSHA Regulated? No
Signs and Symptoms
of Exposure: Dizziness, giddiness, uncoordination, tiredness, drunkenness. Vapor
concentrations above 10,000 ppm may lead to unconsciousness and may be fatal
(asphyxiation). Excess vapor concentrations may induce irregular heart beats.
Medical Conditions Generally Aggravated by Exposure: May increase myocardial
irritability in persons with pre-existing conditions.
EMERGENCY FIRST AID PROCEDURES:
Eyes: Wash with large amounts of tepid water.
Skin: Wash off with mild soap and water.
In either case, if irritation persists, consult a physician.
Inhalation: Remove to fresh air. If breathing has stopped, give artificial respiration.
Seek immediate medical attention.
Ingestion: Do not induce vomiting - seek immediate medical attention.
Note: Components are not classified as carcinogenic by IARC, NTP, or OSHA.
SECTION 6 - PRECAUTIONS FOR SAFE HANDLING AND USE
Steps To Be Taken In Case Material Is Released Or Spilled: (Always wear personal
protective equipment). Evacuate all unprotected personnel. Protected personnel should
remove any possible ignition source. For small spills, mop or wipe up. Remove to out of
doors. Areas may be slippery.
Waste Disposal Method: Dispose of in accordance with local, federal and state
regulations.
Precautions To Be Taken In Handling and Storing: Do not puncture, incinerate,
expose to open flame or temperature above 120癋. Keep out of direct sunlight.
Other Precautions: Read label precautions. For industrial use only. Keep out of reach
of children. Contents are under pressure.
SECTION 7 - CONTROL MEASURES
Respiratory Protection (Specify Type):
Ventilation: Local exhaust as needed to keep vapor concentrations below the TLV's.
Mechanical (general): In low lying, confined or poorly ventilated areas where vapors
tend to accumulate and displace air.
Protective Gloves: Impervious gloves with MYLAR-coated Durafab (2nd choice PVA or
neoprene) for repeated exposure.
Eye Protection: Proper eye protection should be worn in any type of industrial
operation.
Work/Hygienic Practices: When not in use keep protective cap in place to prevent
accidental spraying.
