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
frostbite.
HUMAN HEALTH EFFECTS:
Skin contact may cause frostbite from exposure to the
liquid. Inhalation may include nonspecific discomfort, such
as nausea, headache, or weakness; or temporary nervous
system depression with anesthetic effects such as dizziness,
headache, confusion, incoordination, and loss of
consciousness.
Higher exposures to vapors may lead to these effects:
temporary lung irritation effects with cough, discomfort,
difficulty breathing, or shortness of breath; temporary
alteration of the heart's electrical activity with irregular
pulse, palpitations, or inadequate circulation; abnormal
kidney functon as detected by laboratory tests; or fatality
from gross overexposure. Individuals with preexisting
diseases of the central nervous system, cardiovascular
system, lungs or kidneys 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
Flush skin with water for at least 15 minutes after excessive
contact. Seek medical assistance if irritation is present. Wash
contaminated clothing before reuse. 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 possible disturbances 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 : No flash point
Flammable Limits in Air, % by Volume:
LEL : None per ASTM E681
UEL : None per ASTM E681
Autoignition: 681 C (1258 F) R-401A
685 C (1265 F) R-401B
Fire and Explosion Hazards:
Cylinders may rupture under fire conditions. Decomposition
may occur.
Contact of welding or soldering torch flame with high
concentrations of refrigerant can result in visible changes
in the size and color of torch flames. This flame effect
will only occur in concentrations of product well above the
recommended exposure limit, therefore stop all work and
ventilate to disperse refrigerant vapors from the work area
before using any open flames.
Commercial Food Equipment Service Association P_0000060316 D_0000066461
MSDS Number: 3030FR Page 4 of 9
R-401A and R-401B are not flammable in air at temperatures
up to 100 deg C (212 deg F) at atmospheric pressure.
However, mixtures of these products with high concentrations
of air at elevated pressure and/or temperature can become
combustible in the presence of an ignition source. These
products can also become combustible in an oxygen enriched
environment (oxygen concentrations greater than that in
air). Whether a mixture containing these products and air,
or these products in an oxygen enriched atmosphere becomes
combustible depends on the inter-relationship of 1) the
temperature 2) the pressure, and 3) the proportion of oxygen
in the mixture. In general, these products should not be
allowed to exist with air above atmospheric pressure or at
high temperatures; or in an oxygen enriched environment.
For example: these products should NOT be mixed with air
under pressure for leak testing or other purposes.
Experimental data have also been reported which indicate
combustibility of HCFC-22, a component in these products, in
the presence of chlorine.
Extinguishing Media
Use media appropriate for surrounding material.
Fire Fighting Instructions
Cool tank/container with water spray. Self-contained breathing
apparatus (SCBA) may be 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.
Ventilate area, especially low or enclosed places where heavy
vapors might collect. Remove open flames. Use self-contained
breathing apparatus (SCBA) if large spill or leak occurs.
Spill Clean Up
Comply with Federal, State, and local regulations for reporting
releases.
HANDLING AND STORAGE
Handling (Personnel)
Avoid breathing vapors or mist. Avoid contact with eyes or skin.
Commercial Food Equipment Service Association P_0000060316 D_0000066461

Use with sufficient ventilation to keep employee exposure below
recommended limits.
Storage
Store in a clean, dry place. Do not heat above 52 C (126 F).
EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls
Use sufficient ventilation to keep employee exposure below
recommended limits. Local exhaust should be used when large
amounts are released. Mechanical ventilation should be used in
low or enclosed places. Refrigerant concentration monitors may be
necessary to determine vapor concentrations in work areas prior to
use of torches or other open flames, or if employees are entering
enclosed areas.
Personal Protective Equipment
Lined butyl gloves should be used to avoid prolonged or repeated
exposure.
Chemical splash goggles should be available for use as needed to
prevent eye contact.
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.

TOXICOLOGICAL INFORMATION
Animal Data
The blend is untested.
CHLORODIFLUOROMETHANE (HCFC-22)
Inhalation 4-hour LC50: 220,000 ppm in rats
The compound is a skin irritant and a slight eye irritant, but is
not a skin sensitizer in animals.
Effects from single high exposures include central nervous system
depression, anesthesia, rapid breathing, lung congestion and
microscopic liver changes. Cardiac sensitization occurred in dogs
at 50,000 ppm or greater from the action of exogenous epinephrine.
No toxic effects or abnormal histopathological observations
occurred in rats repeatedly exposed to concentrations ranging from
10,000 to 50,000 ppm (v/v). Long-term exposures to 50,000 ppm
(v/v) of vapors produced organ weight increases and a decrease in
body weight gain, but no increased mortality or adverse
hematological effects.
In chronic inhalation studies, HCFC-22, at a concentration of
50,000 ppm (v/v), produced a small, but statistically significant
increase of late-occurring tumors involving salivary glands in
male rats, but not female rats or male or female mice. In the
same studies, no increased incidence of tumors was seen in either
species at concentrations of 10,000 ppm or 1000 ppm (v/v).
Long-term administration in corn oil produced no effects on body
weight or mortality.
HCFC-22 was mutagenic in some strains of bacteria in cell
cultures, but not in mammalian cell cultures or animals. It did
not cause heritable genetic damage in mammals.
A slight, but significant increase in developmental toxicity was
observed at high concentrations (50,000 ppm) of HCFC-22, a
concentration which also produced toxic effects in the adult
Commercial Food Equipment Service Association P_0000060316 D_0000066461
MSDS Number: 3030FR Page 8 of 9
animal. Based on these findings, and other negative developmental
studies, HCFC-22 is not considered a unique hazard to the
conceptus. Studies of the effects of HCFC-22 on male reproductive
performance have been negative. Specific studies to evaluate the
effect on female reproductive performance have not been conducted,
however, limited information obtained from studies on
developmental toxicity do not indicate adverse effects on female
reproductive performance at concentrations up to 50,000 ppm.
DIFLUOROETHANE (HFC-152a)
Inhalation 4-hour ALC : 383,000 ppm in rats
Oral ALD : >1,500 mg/kg in rats
Effects of a single exposure to high levels include labored
breathing, lung irritation, lethargy, incoordination and loss of
consciousness. Cardiac sensitization occurred in dogs exposed to
a concentration of 150,000 ppm in air and given an intravenous
epinephrine challenge. Effects of repeated exposure include
increased urinary fluoride, reduced kidney weight, and reversible
kidney changes.
Effects of a single high oral dose include weight loss and
lethargy.
Tests in animals demonstrate no carcinogenic activity or
developmental effects. Tests in animals for reproductive effects
have not been performed. This compound does not produce genetic
damage in bacterial cell cultures but has not been tested in
animals.
CHLOROTETRAFLUOROETHANE (HCFC-124)
Inhalation 4-hour ALC : >230,000 ppm in rats
The effects in animals from single inhalation exposures by
inhalation include central nervous system effects, anesthesia and
decreased blood pressure. Cardiac sensitization occurred in dogs
exposed to a concentration of 2.5% in air and given an intravenous
epinephrine challenge. Repeated exposures produced increased
liver weights, anesthetic effects, irregular respiration, poor
coordination and nonspecific effects such as decreased body weight
gain. However, no irreversible effects were seen as evidenced by
histopathologic evaluation.
Tests in animals suggest no developmental toxicity potential.
HCFC-124 was not mutagenic in bacterial and mammalian cell
cultures or whole animal studies.
