# Potential Health Effects
Skin contact may include frostbite from exposure to the
liquid.
Inhalation may include nonspecific discomfort, such as
nausea, headache, or weakness; or temporary nervous system

depression with anaesthetic effects such as dizziness,
headache, confusion, incoordination, and loss of
consciousness.
Higher exposures (> 20%) may lead to temporary alteration of
the heart's electrical activity with irregular pulse,
palpitations, or inadequate circulation. Data to evaluate
the skin permeation hazard of this compound are
insufficient. There are no reports of human sensitization.
Individuals with preexisting diseases of the central nervous
system, 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 persons calm. If not breathing, give
artificial respiration. If breathing is difficult, give
oxygen. Call a physician.
SKIN CONTACT
In case of skin contact, flush with water for 15 minutes.
Treat for frostbite if necessary by gently warming
affected areas. Get medical attention if irritation is
present.
EYE CONTACT
In case of eye contact, immediately flush eyes with
plenty of water for 15 minutes. Call a physician.
IF SWALLOWED
Ingestion is not considered a potential route of
exposure.
Notes to Physicians
Because of possible disturbances of cardiac rhythm,
catecholamine drugs, such as epinephrine, should 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 : Not determined
Autodecomposition Temperature:
Dichlorodifluoromethane: <760 deg C (<1400 deg F)
Difluoroethane : <445 deg C (<836 deg F)
Fire and Explosion Hazards:
Use water spray or fog to cool containers. Cylinders are
equipped with temperature and pressure relief devices but
may still rupture under fire conditions. Decomposition
may occur.
Extinguishing Media
As appropriate for combustibles in area.
Fire Fighting Instructions
Self-contained breathing apparatus (SCBA) is required
if cylinders rupture or release under fire conditions.
----------------------------------------------------------------------
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 places where heavy vapors
might collect. Wear self-contained breathing apparatus
(SCBA) for large spills. Remove open flames.

Material Safety Data Sheet
----------------------------------------------------------------------
HANDLING AND STORAGE
----------------------------------------------------------------------
Handling (Personnel)
Avoid breathing vapors. Avoid liquid contact with skin or
eyes. Use with sufficient ventilation to keep employee
exposure below recommended limits.
Storage
Clean, dry area. Do not heat above 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 places.
Personal Protective Equipment
Impervious gloves and chemical splash goggles should be used
if contact with liquid is possible. Under normal
manufacturing conditions no respiratory protection is
required when using this product. Self-contained
breathing apparatus (SCBA) is required if a spill occurs.
Exposure Guidelines
Applicable Exposure Limits
METHANE, DICHLORODIFLUORO- (R-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
