3. Hazard Identification
Emergency Overview: Colorless liquid with a slight ethereal odor.
This product is nonflammable. Liquid will irritate eyes and skin
under repeated or prolonged exposure. Product vapors displace air
and can cause asphyxiation especially in confined spaces.
Potential Health Effects:
Eyes: Moderate irritation. Persons wearing contact lenses should wear
chemical protective safety glasses when exposed to this product.
Skin: For repeated contact: dry/chapped skin, risk of chronic dermatitis.
Ingestion: Harmful if swallowed. Irritates the mouth, throat and stomach.
Inhalation: Inhalation of high concentrations of vapor is harmful and
may cause heart irregularities, unconsciousness, or death. Intentional
misuse or deliberate inhalation may cause death without warning.
Medical Conditions Aggravated by Exposure: Preexisting disease of
the heart, lungs, skin and eyes.
4. First Aid Measures
Eyes: Immediately flush with water. Remove any contact lenses and
continue flushing for 15 minutes, lifting eyelids occasionally until
no evidence of the chemical remains. If irritation develops or
persists call a physician.
Skin: Wash promptly with soap and water. Remove contaminated
clothing and shoes and replace with clean clothing.
Ingestion: DO NOT induce vomiting. Immediately give two
glasses of water. Never give anything by mouth to an unconscious
person. Call a physician.
Inhalation: Remove to fresh air. Keep person calm. If not breath-
ing, give artificial respiration. If breathing is difficult, give oxygen.
Call a physician.

Extinguishing Media:Extinguishing Media:Extinguishing Media:Extinguishing Media:Extinguishing Media: CO2, dry chemical, water spray, water fog
Special Firefighting Procedures: Evacuate personnel. Wear self
contained breathing apparatus (SCBA) and full protective equipment.
Containers generate pressure when heated causing violent bursting
and dangerous propelling of container. May form toxic decomposi-
tion products above 480o F/ 250o C.
Spill or Leak: Evacuate area, absorb spilled liquid with commercial,
nonflammable absorbent i.e. sand, vermiculite. Remove unprotected
personnel. Protected personnel should remove ignition sources and shut
off fire sources. Provide ventilation. Shovel (spark proof) absorbent
material into drums and close. Do not flush to sewer.
7. Handling and Storage
Avoid breathing vapors or mist. Use only with adequate ventilation. Avoid
repeated or prolonged contact with eyes, skin or clothing. Wash thoroughly
after handling. Do not store in direct sunlight. Store in cool dry place, away
from heat, sparks or flames which may generate toxic decomposition
products. Vapors are heavy and may concentrate in low poorly ventilated
areas. Keep away from children.
8. Exposure Controls/Personal Protection
Respiratory Protection: Use only with adequate ventilation. Keep
container tightly closed. Use approved NIOSH self-contained or
supplied air respirators for emergencies and in situations where air
may be displaced by vapors.
Eye Protection: Use chemical protective safety glasses.
Protective Clothing: Where there is potential for skin contact, use
appropriate impervious gloves, apron, pants and jacket.

10. Reactivity
Chemical Stability: Material is stable.
Hazardous Polymerization: Will not occur.
Incompatibilities: Alkali or alkaline earth metals powdered Al, Zn, Be,
Na, Mg, etc. Incompatible w/strong bases such as NaOH, KOH, etc.
Decomposition Products: Decomposes with heat. High temperatures (open
flame, glowing metal surfaces, etc.) can decompose forming hydrofluoric
acid and possibly carbonyl fluoride. This material is incompatible with
strong bases and can react to form salts of hydrofluoric acid and unsatur-
ated compounds of unknown toxicity.
11. Toxicological Information
Toxicity information for the individual components of this product are
listed below.
This material is currently undergoing chronic toxicity testing.
1,1,1,2,3,4,4,5,5,5-decafluoropentane: Oral LD50>5,000 mg/kg in rats.
Dermal ALD > 5,000 mg/kg in rabbits. Inhalation, 4 hour LC50: 11,100
ppm in rats. Animal testing indicates that 1,1,1,2,3,4,4,5,5,5-
decafluoropentane is a slight skin irritant and a mild eye irritant, but is
not a skin sensitizer. Single exposure to 5,000 ppm by inhalation caused
tremors. No cardiac sensitization was observed. A different single
exposure study by inhalation in rats caused incoordination, hyperactivity
and prostration; pathological examination of rats from this study revealed
kidney and lung changes and external hair loss. Repeated exposures to
1,900-3,500 ppm caused tremors or convulsions, behavioral effects, and
altered clinical chemistry. These effects were temporary. In a different
repeated exposure test the No Observed Adverse Effect Level (NOAEL)
for convulsions was 1,000 ppm. Results indicate convulsions is an acute
effect of 1,1,1,2,3,4,4,-5,5,5-decafluoropentane. The 90 day NOAEL
is 500 ppm. In animal testing this material produced developmental
effects only at exposure levels producing other toxic effect in the
adult animal. No animal data are available to define the carcinogenic
or reproductive hazards of this material. Tests have shown that
1,1,1,2,3,4,4,5,5,5-decafluoropentane does not cause genetic damage
in bacterial mammalian cell cultures. It has not produced genetic
damage in tests on animals.
Trans,1,2-dichloroethylene (t-DCE): A severe eye irritant and a moderate
to severe skin irritant. Single and repeated exposure by ingestion caused
increased kidney weight, histopathological changes of the lungs, liver
effects, decreased motor activity, pulmonary edema, cardiovascular
system changes, and mortality. Single and repeated exposure to t-DCE by
inhalation caused pathological changes of the liver and lungs, inactivity/
anaesthesia, altered white blood cell count, cardiovascular system
changes and weak cardiac sensitization, a potentially fatal disturbance of
the heart rhythm caused by heightened sensitivity to the action of
epinephrine. Long term exposure caused altered liverand lung function.
A Dec. 1998 inhalation study conducted with 99.45 pure t-DCE
produced no adverse, compound related effects. The NOEL was
4,000ppm. Exposure of pregnant rats shows maternal toxicity at 2,000,
6,000 & 12,000ppm. Developmental toxicity was seen only at 12,000
ppm. Tests have shown that T-DCE does not cause genetic damage in
bacterial or mammalian cell cultures. No animal data are available to
define the carcinogenic or reproductive hazards of t-DCE.
1,1,1,3,3,Pentafluorobutane: No Federal OSHA PEL (29 CFR 1919.1000) or
ACGIH TLV values are established for this chemical. The manufacturer of this
material (Solvay) has established an AEL as an 8 hour & 12 hour TWA of 500
ppm. Where governmentally imposed occupational exposure limits which are
lower than the above AEL are in effect, such limits shall take precedence.
1,1,1,3,3,Pentafluoropropane: No Federal OSHA PEL (29 CFR 1919.1000) or
ACGIH TLV values are established for this chemical. The manufacturer of this
material (Honeywell) has established a PEL as an 8 hour TWA of 300 ppm.
Where governmentally imposed occupational exposure limits which are lower
than the above PEL are in effect, such limits shall take precedence.
Carcinogenicity: None of the components present in this material are
listed by IARC, NTP, OSHA or ACGIH as a carcinogen.
