Common Name: 2,4-Diaminoanisole Sulfate CAS Number: 39156-41-7 DOT Number: None Date: January, 1989 ----------------------------------------- HAZARD SUMMARY * 2,4-Diaminoanisole Sulfate can affect you when breathed in and by passing through your skin. * 2,4-Diaminoanisole Sulfate should be handled as a CARCINOGEN-- WITH EXTREME CAUTION. * Exposure to large amounts can cause serious poisoning, with trembling, diarrhea, trouble breathing and even death. * 2,4-Diaminoanisole Sulfate can cause both skin and lung allergies to develop. * Contact may cause irritation and possible damage to the eyes. IDENTIFICATION 2,4-Diaminoanisole Sulfate is an off-white to violet powder. It is used in dyes for hair and fur. REASON FOR CITATION * 2,4-Diaminoanisole Sulfate is on the Hazardous Substance List because it is cited by NTP, IARC and EPA. 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 No occupational exposure limits have been established for 2,4- Diaminoanisole Sulfate. This does not mean that this substance is not harmful. Safe work practices should always be followed. * It should be recognized that 2,4-Diaminoanisole Sulfate can be absorbed through your skin, thereby increasing your exposure. * NIOSH recommends reducing exposure to 2,4-Diaminoanisole Sulfate to the lowest feasible level. * 2,4-Diaminoanisole Sulfate may be a CARCINOGEN in humans. There may be no safe level of exposure to a carcinogen, so all contact should be reduced to the lowest possible level. 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 expo-sure to 2,4- Diaminoanisole Sulfate 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 2,4-Diaminoanisole Sulfate 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 2,4-Diaminoanisole Sulfate: * 2,4-Diaminoanisole Sulfate can irritate the eyes on contact. Severe irritation and possible damage may occur. * Exposure to large amounts of 2,4-Diaminoanisole Sulfate, through breathing or skin contact, may cause serious poisoning, with muscle twitching, trembling, nausea, diarrhea, convulsions and even death. Chronic Health Effects The following chronic (long-term) health effects can occur at some time after exposure to 2,4-Diaminoanisole Sulfate and can last for months or years: Cancer Hazard * 2,4-Diaminoanisole Sulfate may be a CARCINOGEN in humans because it has been shown to cause thyroid and mammary cancer in animals. * Many scientists believe there is no safe level of exposure to a carcinogen. Such substances may also have the potential for causing reproductive damage in humans. Reproductive Hazard * There is limited evidence that 2,4-Diaminoanisole Sulfate is a teratogen in animals. Until further testing has been done, it should be treated as a possible teratogen in humans. Other Long-Term Effects * 2,4-Diaminoanisole Sulfate may cause a skin allergy. If allergy develops, very low future exposures can cause itching and a skin rash. * 2,4-Diaminoanisole Sulfate may cause an asthma-like allergy. Future exposures can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness. Medical Testing If symptoms develop or overexposure is suspected, the following may be useful: * Evaluation by a qualified allergist, including careful exposure history and special testing, may help diagnose skin allergy. * Lung function tests. These may be normal if the person is not having an attack at the time of the test. 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. In addition, the following control is recommended: * Where possible, automatically transfer 2,4-Diaminoanisole Sulfate 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 2,4- Diaminoanisole Sulfate 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 2,4- Diaminoanisole Sulfate. * 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 2,4-Diaminoanisole Sulfate, immediately wash or shower to remove the chemical. At the end of the workshift, wash any areas of the body that may have contacted 2,4-Diaminoanisole Sulfate, whether or not known skin contact has occurred. * Do not eat, smoke, or drink where 2,4-Diaminoanisole Sulfate is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating or smoking. * Use a vacuum or a wet method to reduce dust during clean-up. Do not dry sweep. * When vacuuming, a high efficiency particulate absolute (HEPA) filter should be used, not a standard shop vacuum. 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 2,4-Diaminoanisole Sulfate. 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 * Eye protection is included in the recommended respiratory protection. 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 2,4-Diaminoanisole Sulfate does not occur. * At any exposure level, 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.

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. Insufficient data are available to evaluate or predict the short- term effects of 2,4-Diaminoanisole Sulfate to aquatic life, 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. Insufficient data are available to evaluate or predict the long- term effects of 2,4-Diaminoanisole Sulfate to aquatic life, plants, birds, or land animals. WATER SOLUBILITY 2,4-Diaminoanisole Sulfate is highly soluble in water. Concentrations of 1,000 milligrams and more will mix with a liter of water. 2,4-Diaminoanisole Sulfate reacts with water to form 2,4- Diaminoanisole (CAS No. 615-05-4) and Sulfuric Acid (CAS No. 7664- 93-9). Fact sheets are available for both of these compounds. DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT 2,4-Diaminoanisole Sulfate will react rapidly with water to form 2,4-Diaminoanisole and Sulfuric Acid. Virtually 100% of 2,4- Diaminoanisole 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 2,4-Diaminoanisole Sulfate found in fish tissues is expected to be about the same as the average concentration of 2,4-Diaminoanisole Sulfate in the water from which the fish was taken.
