Common Name: Acrolein CAS Number: 107-02-8 DOT Number: UN 1092 Date: January, 1989 ----------------------------------------- HAZARD SUMMARY * Acrolein can affect you when breathed in and by passing through your skin. * Because this is a MUTAGEN, handle it as a possible cancer causing substance WITH EXTREME CAUTION. * Exposure can cause you to feel dizzy, lightheaded, and to pass out. * Exposure can irritate the lungs, causing coughing and shortness of breath. Higher exposures can cause a buildup of fluid in the lungs (pulmonary edema) and death. * Contact can severely burn the eyes and skin. * It is highly FLAMMABLE and REACTIVE and a FIRE and EXPLOSION HAZARD. IDENTIFICATION Acrolein is a clear, colorless or yellowish liquid with a piercing, disagreeable odor that causes tearing. It is used in making plastics, drugs and tear gas. REASON FOR CITATION * Acrolein is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DEP, NFPA and EPA. * This chemical is also on the Special Health Hazard Substance List because it is a MUTAGEN and is FLAMMABLE and REACTIVE. * Definitions are attached. HOW TO DETERMINE IF YOU ARE BEING EXPOSED * Exposure to hazardous substances should be routinely evaluated. This may include collecting air samples. Under OSHA 1910.20, you have a legal right to obtain copies of sampling results from your employer. 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 = 0.16 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 0.1 ppm averaged over an 8 hour work shift. ACGIH: The recommended airborne exposure limit is 0.1 ppm averaged over an 8 hour workshift and 0.3 ppm as a STEL (short term exposure limit). * Acrolein is a MUTAGEN. Mutagens may have a cancer risk. All contact with this chemical should be reduced to the lowest possible level. * 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 Acrolein. * 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 Acrolein 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 Acrolein: * Contact with the liquid can severely burn the skin and eyes. * Because this is a MUTAGEN, handle it as a possible cancer causing substance WITH EXTREME CAUTION. * Breathing the vapor may irritate the lungs, causing coughing and/or shortness of breath. Higher exposures can cause a buildup of fluid in the lungs (pulmonary edema). This can cause death. * Exposure to the vapor can irritate the eyes, nose, and throat. * Breathing the vapor can cause dizziness, nausea, headaches, and in higher concentrations, unconsciousness and death. Chronic Health Effects The following chronic (long term) health effects can occur at some time after exposure to Acrolein and can last for months or years: Cancer Hazard * Acrolein causes MUTATIONS (genetic changes). Such chemicals may have a cancer risk. * Many scientists believe that 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 insufficient evidence available to the New Jersey Department of Health to evaluate Acrolein for its ability to cause reproductive damage. Additional testing should be done. Other Long Term Effects * Acrolein may cause a skin allergy. If an allergy develops, very low future exposures can cause itching and a skin rash. * Long term exposure can cause drying and cracking of the skin. * Permanent lung damage can occur after a high exposure or repeated lower exposures. MEDICAL Medical Testing Before beginning employment and at regular times after that, the following are recommended: * Lung function tests. If symptoms develop or overexposure has occurred, the following may be useful: * Evaluation by a qualified allergist, including careful exposure history and special testing, may help diagnose skin allergy. * Consider chest x ray after acute overexposure. 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 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 Acrolein 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 Acrolein should change into clean clothing promptly. * Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to Acrolein. * 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 Acrolein, immediately wash or shower to remove the chemical. * Wash any areas of the body that may have contacted Acrolein at the end of each workday, whether or not known skin contact has occurred. * Do not eat, smoke, or drink where Acrolein 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 Acrolein. 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. Eye Protection * Wear splash proof chemical goggles and face shield when working with liquid Acrolein, 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. * Engineering controls must be effective to ensure that exposure to Acrolein does not occur. * Where the potential exists for exposures over 0.1 ppm, use a MSHA/NIOSH approved supplied air respirator with a full facepiece operated in the positive pressure mode or with a full face piece, 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. * Exposure to 5 ppm is immediately dangerous to life and health. If the possibility of exposures above 5 ppm exists, use a MSHA/NIOSH approved self contained breathing apparatus with a full facepiece operated in continuous flow or other positive pressure mode. HANDLING AND STORAGE * Prior to working with Acrolein you should be trained on its proper handling and storage. * Acrolein must be stored to avoid contact with ACIDS; OXIDIZERS (such as PEROXIDES, CHLORATES, PERCHLORATES, NITRATES, and PERMANGANATES), or ALKALINE MATERIALS (such as CAUSTICS, AMMONIA, or AMINES), because violent reactions occur. * Store in tightly closed containers in a cool, well ventilated area away from HEAT. The reaction is speeded up by heat, even when an inhibitor is used. * Sources of ignition, such as smoking and open flames, are prohibited where Acrolein is handled, used, or stored. * Metal containers involving the transfer of 5 gallons or more of Acrolein 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 Acrolein. * Wherever Acrolein is used, handled, manufactured, or stored, use explosion proof electrical equipment and fittings.

It may enter the environment through its main use as an aquatic herbicide or by 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. Acrolein has high acute toxicity to aquatic life. As an aquatic herbicide, acrolein has high acute toxicity to water plants and may be expected to adversely effect land plants. Acrolein has high acute toxicity to birds and moderate acute toxicity to 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. Acrolein has high chronic toxicity to aquatic life. No data are available on the long-term effects of acrolein to plants, birds, or land animals. WATER SOLUBILITY Acrolein is moderately soluble in water. Concentrations of between 1 and 1,000 milligrams will mix with a liter of water. DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT Acrolein is slightly persistent in the aquatic environment 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 77% of acrolein 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 acrolein found in fish tissues is expected to be somewhat higher than the average concentration of acrolein in the water from which the fish was taken.
