DOT Number: None
Date: October 30, 1986
-----------------------------------------
HAZARD SUMMARY
* 1,1,2-Trichloro-1,2,2-Trifluoroethane can affect you when
breathed in.
* High exposure may cause the heart to beat irregularly or stop.
This can cause death.
* Exposure can cause you to feel sleepy and lose your ability to
concentrate.
* It can cause irritation of the eyes, nose, and throat.
* Repeated skin exposure can cause irritation and rash.
IDENTIFICATION
1,1,2-Trichloro-1,2,2-Trifluoroethane is a colorless liquid with an
ether like odor at high concentrations. It is used as a dry
cleaning solvent and refrigerant.
REASON FOR CITATION
* 1,1,2-Trichloro-1,2,2-Trifluoroethane is on the RTK Hazardous
Substance List because it is regulated by OSHA and cited by
ACGIH.
* Definitions are attached.
HOW TO DETERMINE IF YOU ARE BEING EXPOSED
* Exposure to hazardous substances should be routinely
evaluated. This may include collecting personal and area air
samples. You can obtain copies of sampling results from your
employer. You have a legal right to this information under
OSHA 1910.20.
* If you think you are experiencing any work related health
problems, see a doctor trained to recognize occupational
diseases. Take this Fact Sheet with you.
* ODOR THRESHOLD = 45 ppm.
* The odor threshold only serves as a warning of exposure. Not
smelling it does not mean you are not being exposed.
WORKPLACE EXPOSURE LIMITS
OSHA: The legal airborne permissible exposure limit (PEL) is
1,000 ppm averaged over an 8 hour workshift.
ACGIH: The recommended airborne exposure limit is 1,000 ppm
averaged over an 8 hour workshift and 1,250 ppm as a
STEL (short term exposure limit).
WAYS OF REDUCING EXPOSURE
* Where possible, enclose operations and use local exhaust
ventilation at the site of chemical release. If local exhaust
ventilation or enclosure is not used, respirators should be
worn.
* Wear protective work clothing.
* Post hazard and warning information in the work area. In
addition, as part of an ongoing education and training effort,
communicate all information on the health and safety hazards
of 1,1,2-Trichloro-1,2,2-Trifluoroethane to potentially
exposed workers.
This Fact Sheet is a summary source of information of all potential
and most severe health hazards that may result from exposure.
Duration of exposure, concentration of the substance and other
factors will affect your susceptibility to any of the potential
effects described below.
------------------------------------------
HEALTH HAZARD INFORMATION
Acute Health Effects
The following acute (short term) health effects may occur
immediately or shortly after exposure to 1,1,2-Trichloro-1,2,2-
Trifluoroethane:
* Exposure can irritate the eyes, nose, and throat.
* Breathing high concentrations of 1,1, 2 Trichloro 1,2,2
Trifluoroethane can cause the heart to beat irregularly or
stop. This can cause death.
* Exposure can cause you to feel sleepy and have trouble
concentrating.
Chronic Health Effects
The following chronic (long term) health effects can occur at some
time after exposure to 1,1,2-Trichloro-1,2,2-Trifluoroethane and
can last for months or years:
* Repeated exposure may cause skin irritation and rash.
Cancer Hazard
* According to the information presently available to the New
Jersey Department of Health, 1,1,2-Trichloro-1,2,2-
Trifluoroethane has not been tested for its ability to cause
cancer in animals.
Reproductive Hazard
* According to the information presently available to the New
Jersey Department of Health, 1,1,2-Trichloro-1,2,2-
Trifluoroethane has not been tested for its ability to
adversely affect reproduction.
MEDICAL
Medical Testing
If symptoms develop or overexposure is suspected, the following may
be useful:
* Special 24 hour EKG (Holter monitor) to look for irregular
heart beat.
Any evaluation should include a careful history of past and present
symptoms with an exam. Medical tests that look for damage already
done are not a substitute for controlling exposure.
Request copies of your medical testing. You have a legal right to
this information under OSHA 1910.20.
WORKPLACE CONTROLS AND PRACTICES
Unless a less toxic chemical can be substituted for a hazardous
substance, ENGINEERING CONTROLS are the most effective way of
reducing exposure. The best protection is to enclose operations
and/or provide local exhaust ventilation at the site of chemical
release. Isolating operations can also reduce exposure. Using
respirators or protective equipment is less effective than the
controls mentioned above, but is sometimes necessary.
In evaluating the controls present in your workplace, consider: (1)
how hazardous the substance is, (2) how much of the substance is
released into the workplace and (3) whether harmful skin or eye
contact could occur. Special controls should be in place for highly
toxic chemicals or when significant skin, eye, or breathing
exposures are possible.
Good WORK PRACTICES can help to reduce hazardous exposures. The
following work practices are recommended:
* Workers whose clothing has been contaminated by 1,1,2-
Trichloro-1,2,2-Trifluoroethane should change into clean
clothing promptly.
* Contaminated work clothes should be laundered by individuals
who have been informed of the hazards of exposure to 1,1,2-
Trichloro-1,2,2-Trifluoroethane.
* Wash any areas of the body that may have contacted 1,1,2-
Trichloro-1,2,2-Trifluoroethane at the end of each work day,
whether or not known skin contact has occurred.
* Do not eat, smoke, or drink where 1, 1,2 Trichloro 1,2,2
Trifluoroethane is handled, processed, or stored, since the
chemical can be swallowed. Wash hands carefully before eating
or smoking.
* Do not smoke in the work area. Even a little vapor inhaled
through a burning cigarette, cigar, or pipe will be converted
into more highly toxic substances.
PERSONAL PROTECTIVE EQUIPMENT
WORKPLACE CONTROLS ARE BETTER THAN PERSONAL PROTECTIVE EQUIPMENT.
However, for some jobs (such as outside work, confined space entry,
jobs done only once in a while, or jobs done while workplace
controls are being installed), personal protective equipment may be
appropriate.
The following recommendations are only guidelines and may not apply
to every situation.
Clothing
* Avoid skin contact with 1,1,2-Trichloro-1,2,2-Trifluoroethane.
Wear solvent resistant gloves and clothing. Safety equipment
suppliers/manufacturers can provide recommendations on the
most protective glove/clothing material for your operation.
* All protective clothing (suits, gloves, footwear, headgear)
should be clean, available each day, and put on before work.
Eye Protection
* Wear splash proof chemical goggles when working with liquids
containing 1,1,2 Trichloro 1,2,2, Trifluoroethane, unless full
facepiece respiratory protection is worn.
Respiratory Protection
IMPROPER USE OF RESPIRATORS IS DANGEROUS. Such equipment should
only be used if the employer has a written program that takes into
account workplace conditions, requirements for worker training,
respirator fit testing and medical exams, as described in OSHA
1910.134.
* Where the potential exists for exposures over 1,000 ppm, use
an MSHA/NIOSH approved respirator with an organic vapor
cartridge/canister. More protection is provided by a full
facepiece respirator than by a halfmask respirator, and even
greater protection is provided by a powered air purifying
respirator.
* If while wearing a filter, cartridge or canister respirator,
you can smell, taste, or otherwise detect 1,1,2-Trichloro-
1,2,2-Trifluoroethane, or in the case of a full facepiece
respirator you experience eye irritation, leave the area
immediately. Check to make sure the respirator to face seal is
still good. If it is, replace the filter, cartridge, or
canister. If the seal is no longer good, you may need a new
respirator.
* Be sure to consider all potential exposures in your workplace.
You may need a combination of filters, prefilters, cartridges,
or canisters, to protect against different forms of a chemical
(such as vapor and mist) or against a mixture of chemicals.
* Where the potential for high exposures exists, use a
MSHA/NIOSH approved supplied air respirator with a full
facepiece operated in the positive pressure mode or with a
full facepiece, hood, or helmet in the continuous flow mode.
* Exposure to 4,500 ppm is immediately dangerous to life and
health. If the possibility of exposures above 4,500 ppm exists
use an MSHA/NIOSH approved self contained breathing apparatus
with a full facepiece operated in continuous flow or other
positive pressure mode.

ECOLOGICAL INFORMATION
1,1,2-Trichloro-1,2,2-Trifluoroethane is a liquid at room
temperature. It is used as a solvent and degreasing agent in the
aerospace and electronics industry, in the synthesis of fluorovinyl
compounds, and in the production of rigid polyurethane foam. It
may enter the environment from industrial discharges or spills.
ACUTE (SHORT-TERM) ECOLOGICAL EFFECTS
Acute toxic effects may include the death of animals, birds, or
fish, and death or low growth rate in plants. Acute effects are
seen two to four days after animals or plants come in contact with
a toxic chemical substance.
1,1,2-Trichloro-1,2,2-Trifluoroethane has moderate acute toxicity
to aquatic life. Insufficient data are available to evaluate or
predict the short-term effects of 1,1,2-Trichloro-1,2,2-
Trifluoroethane to plants, birds, or land animals.
CHRONIC (LONG-TERM) ECOLOGICAL EFFECTS
Chronic toxic effects may include shortened lifespan, reproductive
problems, lower fertility, and changes in appearance or behavior.
Chronic effects can be seen long after first exposure(s) to a toxic
chemical.
1,1,2-Trichloro-1,2,2-Trifluoroethane has moderate chronic toxicity
to aquatic life. Insufficient data are available to evaluate or
predict the long-term effects of 1,1,2-Trichloro-1,2,2-
Trifluoroethane to plants, birds, or land animals.
WATER SOLUBILITY
1,1,2-Trichloro-1,2,2-Trifluoroethane is moderately soluble in
water. Concentrations of between 1 to 1,000 milligrams will mix
with a liter of water.
DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT
1,1,2-Trichloro-1,2,2-Trifluoroethane is non-persistent in water,
due to volatilization, with a half-life of less than 2 days. The
half-life of a pollutant is the amount of time it takes for one-
half of the chemical to be degraded. Virtually 100% of 1,1,2-
Trichloro-1,2,2-Trifluoroethane will end up in the air.
BIOACCUMULATION IN AQUATIC ORGANISMS
Some substances increase in concentration, or bioaccumulate, in
living organisms as they breathe contaminated air, drink
contaminated water, or eat contaminated food. These chemicals can
become concentrated in the tissues and internal organs of animals
and humans.
The concentration of 1,1,2-Trichloro-1,2,2-Trifluoroethane found in
fish tissues is expected to be somewhat higher than the average
concentration of 1,1,2-Trichloro-1,2,2-Trifluoroethane in the water
from which the fish was taken.
