HAZARDS IDENTIFICATION
----------------------------------------------------------------------
Potential Health Effects
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. Vapor reduces oxygen available for
breathing and is heavier than air. Liquid contact can cause
2022FR DuPont Page 2
Material Safety Data Sheet
(HAZARDS IDENTIFICATION - Continued)
frostbite. May cause eye irritation.
HUMAN HEALTH EFFECTS:
Human health effects of overexposure by eye contact with the
vapor may include eye irritation with discomfort, tearing,
or blurring of vision. Skin contact with the liquid may
cause frostbite. Inhalation of the vapors may cause
temporary nervous system depression with anesthetic effects
such as dizziness, headache, confusion, incoordination, and
loss of consciousness; temporary alteration of the heart鈥檚
electrical activity with irregular pulse, palpitations, or
inadequate circulation, or the effects of exclusion of
oxygen with grossly excessive exposures.
Individuals with preexisting diseases of the central nervous
or cardiovascular system may have increased susceptibility
to the toxicity of excessive exposures.
Carcinogenicity Information
None of the components present in this material at concentrations
equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH
as a carcinogen.
----------------------------------------------------------------------
FIRST AID MEASURES
----------------------------------------------------------------------
First Aid
INHALATION
If high concentrations are inhaled, immediately remove to
fresh air. Keep person calm. If not breathing, give
artificial respiration. If breathing is difficult, give
oxygen. Call a physician.
SKIN CONTACT
In case of contact, flush skin with water. Treat for
frostbite if necessary by gently warming affected area.
EYE CONTACT
In case of contact, immediately flush eyes with plenty of
water for at least 15 minutes. Call a physician.
INGESTION
Ingestion is not considered a potential route of
exposure.

Notes to Physicians
Because of a possible disturbance of cardiac rhythm,
catecholamine drugs, such as epinephrine, should only be
used with special caution in situations of emergency life
support.
----------------------------------------------------------------------
FIRE FIGHTING MEASURES
----------------------------------------------------------------------
Flammable Properties
Flash Point : Will not burn
Flammable limits in Air, % by Volume
LEL : Not applicable
UEL : Not applicable
Autoignition : >750 C (>1382 F)
Fire and Explosion Hazards:
Cylinders may rupture under fire conditions. Decomposition
may occur.
Extinguishing Media
As appropriate for combustibles in area.
Fire Fighting Instructions
Use water spray or fog to cool containers. Self-contained
breathing apparatus (SCBA) is required if cylinders rupture
and contents are released under fire conditions. Water
runoff should be contained and neutralized prior to release.
----------------------------------------------------------------------
ACCIDENTAL RELEASE MEASURES
----------------------------------------------------------------------
Safeguards (Personnel)
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL)
sections before proceeding with clean-up. Use appropriate
PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Accidental Release Measures
Ventilate area, especially low or enclosed places where
heavy vapors might collect. Remove open flames. Use
self-contained breathing apparatus (SCBA) for large spills.
2022FR DuPont Page 4
Material Safety Data Sheet
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Use with sufficient ventilation to keep employee exposure
below recommended limits.
Storage
Clean, dry area. Do not heat above 52 deg C (125 deg F).
----------------------------------------------------------------------
EXPOSURE CONTROLS/PERSONAL PROTECTION
----------------------------------------------------------------------
Engineering Controls
Normal ventilation for standard manufacturing procedures is
generally adequate. Local exhaust should be used when large
amounts are released. Mechanical ventilation should be used
in low or enclosed places.
Personal Protective Equipment
Impervious gloves and chemical splash goggles should be used
when handling liquid. Under normal manufacturing
conditions, no respiratory protection is required when using
this product. Self-contained breathing apparatus (SCBA) is
required if a large release occurs.
# Exposure Guidelines
Applicable Exposure Limits
METHANE, DICHLORODIFLUORO- ("FREON" 12)
PEL (OSHA) : 1,000 ppm, 4,950 mg/m3, 8 Hr. TWA
TLV (ACGIH) : 1,000 ppm, 4,950 mg/m3, 8 Hr. TWA, A4
AEL * (DuPont) : None Established
* AEL is DuPont鈥檚 Acceptable Exposure Limit. Where governmentally
imposed occupational exposure limits which are lower than the AEL
are in effect, such limits shall take precedence.

STABILITY AND REACTIVITY
----------------------------------------------------------------------
Chemical Stability
Material is stable. However, avoid open flames and high
temperatures.
Incompatibility with Other Materials
Incompatible with alkali or alkaline earth metals- powdered
Al, Zn, Be, etc.
Decomposition
Decomposition products are hazardous. "Freon" 12 can be
decomposed by high temperatures (open flames, glowing metal
surfaces, etc.) forming hydrochloric and hydrofluoric acids,
and possibly carbonyl halides. These materials are toxic
and irritating. Contact should be avoided.
Polymerization
Polymerization will not occur.
----------------------------------------------------------------------
TOXICOLOGICAL INFORMATION
----------------------------------------------------------------------
Animal Data
Inhalation 30-minute LC50: 800,000 ppm in rats
Oral ALD : >1,000 mg/kg in rats
Effects in animals from single high exposure by inhalation
include anesthesia and irregular heartbeat (cardiac
arrythmias). Repeated inhalation exposures produced altered
respiratory function. Long-term studies showed no
significant clinical, blood chemistry or pathological
effects following repeated exposures. The effects in
animals from long-term ingestion of this material include
slight alterations in blood chemistry and body weight gain.
No other clinical, biochemical or pathological signs of
toxicity have been observed.
Tests in animals demonstrate no carcinogenic activity and no
developmental or reproductive toxicity. The compound does
not produce heritable genetic damage in animals or genetic
damage in bacterial and mammalian cell cultures.
