Common Name: 1,3-Dichloropropene CAS Number: 542-75-6 DOT Number: UN 2047 Date: May 1, 1986 ----------------------------------------- HAZARD SUMMARY * 1,3-Dichloropropene can affect you when breathed in and by passing through your skin. * Exposure can cause headaches, chest pain, and dizziness. High levels can cause you to pass out. * Contact can severely burn the eyes and skin, with permanent damage. * High exposures can damage the kidneys, liver and lungs. * 1,3-Dichloropropene is a FLAMMABLE LIQUID and a FIRE HAZARD. IDENTIFICATION 1,3-Dichloropropene is a straw colored liquid with a sharp, sweet irritating odor. It is used as a soil fumigant. REASON FOR CITATION * 1,3-Dichloropropene is on the Hazardous Substance List because it is cited by ACGIH, DOT, DEP and NFPA. * This chemical is on the Special Health Hazard Substance List because it is FLAMMABLE. * 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. WORKPLACE EXPOSURE LIMITS ACGIH: The recommended airborne exposure limit is 1 ppm averaged over an 8 hour workshift. * The above exposure limits are for air levels only. When skin contact also occurs, you may be overexposed, even though air levels are less than the limits listed above. 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. * Wash thoroughly immediately after exposure to 1,3- Dichloropropene and at the end of the workshift. * 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 1,3-Dichloropropene 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 1,3-Dichloropropene: * A single large exposure to 1,3-Dichloropropene may damage the kidneys, liver and lungs. * Exposure can cause headache, chest pain, dizziness and with higher levels, loss of consciousness. * Contact can cause severe eye burns, with permanent damage. It can also cause severe skin burns. * Breathing 1,3-Dichloropropene can irritate the nose and throat. Higher levels can irritate the lungs causing coughing and/or shortness of breath. Chronic Health Effects The following chronic (long term) health effects can occur at some time after exposure to 1,3-Dichloropropene and can last for months or years: Cancer Hazard * There is limited evidence that 1,3-Dichloropropene causes cancer in animals. It may cause cancer of stomach, lung and liver cancer. There is also limited evidence that 1, 3 Dichloropropene causes cancer in humans. Until further research is done, it should be handled as a probable carcinogen in humans. * Many scientists believe there is no safe level of exposure to a cancer causing agent. Such substances may also have the potential for causing reproductive damage in humans. Reproductive Hazard * There is no evidence that 1,3-Dichloropropene adversely affects reproduction. This is based on test results presently available to the New Jersey Department of Health from published studies. Other Long Term Effects * Repeated exposures can damage the kidneys, liver and lungs. * 1,3-Dichloropropene may cause chronic headache, chest pain and change in personality. MEDICAL Medical Testing Before beginning employment and at regular times after that, the following are recommended: * Liver function tests. * Lung function tests. * Kidney function tests. 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. Mixed Exposures * Because more than light alcohol consumption can cause liver damage, drinking alcohol can increase the liver damage caused by 1,3-Dichloropropene. * Because smoking can cause heart disease, as well as lung cancer, emphysema, and other respiratory problems, it may worsen respiratory conditions caused by chemical exposure. Even if you have smoked for a long time, stopping now will reduce your risk of developing health problems. 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. In addition, the following control is recommended: * Where possible, automatically pump liquid 1,3-Dichloropropene from drums or other storage containers to process containers. Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended: * Workers whose clothing has been contaminated by 1,3- Dichloropropene should change into clean clothing promptly. * Do not take contaminated work clothes home. Family members could be exposed. * Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to 1,3- Dichloropropene. * Eye wash fountains should be provided in the immediate work area for emergency use. * If there is the possibility of skin exposure, emergency shower facilities should be provided. * On skin contact with 1,3-Dichloropropene, immediately wash or shower to remove the chemical. At the end of the workshift, wash any areas of the body that may have contacted 1,3- Dichloropropene, whether or not known skin contact has occurred. * Do not eat, smoke, or drink where 1,3-Dichloropropene is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating or smoking. 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 1,3-Dichloropropene. Wear protective 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. * 1,3-Dichloropropene penetrates rubber and other materials rapidly. For continuous exposure, use Neoprene or equivalent, as recommended by manufacturers. Eye Protection * Wear splash proof chemical goggles and face shield when working with liquid 1,3-Dichloropropene, unless full facepiece respiratory protection is worn. * If exposed to the vapor, wear gas proof goggles and face shield, 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 ppm, 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, or use a MSHA/NIOSH approved self contained breathing apparatus with a full facepiece operated in pressure demand or other positive pressure mode. HANDLING AND STORAGE * Prior to working with 1,3-Dichloropropene you should be trained on its proper handling and storage. * 1,3-Dichloropropene must be stored to avoid contact with ALUMINUM or MAGNESIUM COMPOUNDS; SUBSTANCES CONTAINING FLUORINE, CHLORINE, BROMINE or IODINE; and ALKALINE or CORROSIVE MATERIALS since violent reactions occur. * Store in tightly closed containers in a cool well ventilated area away from HEAT. Separate outside storage is preferred. * Sources of ignition such as smoking and open flames are prohibited where 1,3-Dichloropropene is handled, used, or stored. * Metal containers involving the transfer of 5 gallons or more of 1,3-Dichloropropene should be grounded and bonded. Drums must be equipped with self closing valves, pressure vacuum bungs, and flame arresters. * Use only non sparking tools and equipment, especially when opening and closing containers of 1,3-Dichloropropene.

It may enter the environment from industrial discharges or runoff from agricultural land. 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. 1,3-Dichloropropene has moderate acute toxicity to aquatic life. It has caused size decrease, stunting, and yield decreases in various crops. Insufficient data are available to evaluate or predict the short-term effects of 1,3-dichloropropene to 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. 1,3-Dichloropropene has moderate chronic toxicity to aquatic life. Insufficient data are available to evaluate or predict the long- term effects of 1,3-dichloropropene to plants, birds, or land animals. WATER SOLUBILITY 1,3-Dichloropropene is highly soluble in water. Concentrations of 1,000 milligrams and more will mix with a liter of water. DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT 1,3-Dichloropropene is slightly persistent in water, with a half- life of between 2 to 20 days. The half-life of a pollutant is the amount of time it takes for one-half of the chemical to be degraded. About 95% of 1,3-dichloropropene will eventually end up in air; the rest will end up in the water. 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 1,3-dichloropropene found in fish tissues is expected to be about the same as the average concentration of 1,3- dichloropropene in the water from which the fish was taken.
