Common Name: 1,1,2-Trichloro-1,2,2-Trifluoroethane CAS Number: 76-13-1 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.

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.
