␣For each individual hazardous ingredient, read the New Jersey Department of Health and Senior Services Hazardous Substance Fact Sheet, available on the RTK Program website (www.nj.gov/health/eoh/rtkweb) or in your facility's RTK Central File or Hazard Communication Standard file.
␣You have a right to this information under the New Jersey Worker and Community Right to Know Act and the Public Employees Occupational Safety and Health (PEOSH) Act if you are a public worker in New Jersey, and under the federal Occupational Safety and Health Act (OSHA) if you are a private worker.
␣The New Jersey Right to Know Act requires most employers to label chemicals in the workplace and requires public employers to provide their employees with information concerning chemical hazards and controls. The federal OSHA Hazard Communication Standard (29 CFR 1910.1200) and the PEOSH Hazard Communication Standard (N.J.A.C. 12:100-7) require employers to provide similar information and training to their employees.
This Fact Sheet is a summary of available information regarding the 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.
Acute Health Effects
The following acute (short-term) health effects may occur immediately or shortly after exposure to Methyl Alcohol:
␣Contact can cause skin irritation. ␣Methyl Alcohol can irritate the eyes and can cause blurred
vision and blindness. ␣Inhaling Methyl Alcohol can irritate the nose, throat and
lungs causing coughing, wheezing and/or shortness of
breath. ␣Methyl Alcohol can cause nausea, vomiting, diarrhea and
abdominal pain. ␣Exposure to high concentrations can cause headache,
dizziness, drowsiness, fatigue, loss of consciousness and death.
Chronic Health Effects
The following chronic (long-term) health effects can occur at some time after exposure to Methyl Alcohol and can last for months or years:
Cancer Hazard
␣There is no evidence that Methyl Alcohol causes cancer in animals. This is based on test results presently available to the NJDHSS from published studies.
Reproductive Hazard
␣Methyl Alcohol may be a TERATOGEN in humans since it is a teratogen in animals.
Other Effects
␣Prolonged or repeated contact can cause a skin rash, dryness, redness and cracking of the skin.
␣Methyl Alcohol may damage the liver, kidneys and nervous system.
Medical Testing
For frequent or potentially high exposure (half the PEL or greater), the following are recommended before beginning work and at regular times after that:
␣Liver function tests If symptoms develop or overexposure is suspected, the
following are recommended:
␣Kidney function tests ␣Exam of the nervous system ␣Exam of the eye and vision.
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 the OSHA Access to Employee Exposure and Medical Records Standard (29 CFR 1910.1020).
Mixed Exposures
␣More than light alcohol consumption can cause liver damage. Drinking alcohol can increase the liver damage caused by Methyl Alcohol.

Workplace Controls and Practices
Very toxic chemicals, or those that are reproductive hazards or sensitizers, require expert advice on control measures if a less toxic chemical cannot be substituted. Control measures include: (1) enclosing chemical processes for severely irritating and corrosive chemicals, (2) using local exhaust ventilation for chemicals that may be harmful with a single exposure, and (3) using general ventilation to control exposures to skin and eye irritants. For further information on workplace controls, consult the NIOSH document on Control Banding at www.cdc.gov/niosh/topics/ctrlbanding/.
The following work practices are also recommended:
␣Label process containers. ␣Provide employees with hazard information and training. ␣Monitor airborne chemical concentrations. ␣Use engineering controls if concentrations exceed
recommended exposure levels. ␣Provide eye wash fountains and emergency showers. ␣Wash or shower if skin comes in contact with a hazardous
material. ␣Always wash at the end of the workshift. ␣Change into clean clothing if clothing becomes
contaminated. ␣Do not take contaminated clothing home. ␣Get special training to wash contaminated clothing. ␣Do not eat, smoke, or drink in areas where chemicals are
being handled, processed or stored. ␣Wash hands carefully before eating, smoking, drinking,
applying cosmetics or using the toilet.
In addition, the following may be useful or required:
␣Before entering a confined space where Methyl Alcohol may be present, check to make sure that an explosive concentration does not exist.
The OSHA Personal Protective Equipment Standard (29 CFR 1910.132) requires employers to determine the appropriate personal protective equipment for each hazard and to train employees on how and when to use protective equipment.
The following recommendations are only guidelines and may not apply to every situation.
Gloves and Clothing ␣Avoid skin contact with Methyl Alcohol. Wear personal
protective equipment made from material that can not be permeated or degraded by this substance. Safety equipment suppliers and manufacturers can provide recommendations on the most protective glove and clothing material for your operation.
␣The recommended glove materials for Methyl Alcohol are Butyl, Viton and Barrier®.
␣The recommended protective clothing materials for Methyl Alcohol are Tychem® SL, CSM and TK; and Trellchem® HPS and VPS, or the equivalent.
␣All protective clothing (suits, gloves, footwear, headgear) should be clean, available each day, and put on before work.
Eye Protection
␣Wear indirect vent goggles when working with liquids that may splash, spray or mist. A face shield is also required if the liquid is severely irritating or corrosive to the skin and eyes.
␣Do not wear contact lenses when working with this substance.
Respiratory Protection
Improper use of respirators is dangerous. Respirators should only be used if the employer has implemented a written program that takes into account workplace conditions, requirements for worker training, respirator fit testing, and medical exams, as described in the OSHA Respiratory Protection Standard (29 CFR 1910.134).
␣Where the potential exists for exposure over 200 ppm, use a NIOSH approved supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode. For increased protection use in combination with an auxiliary self-contained breathing apparatus or an emergency escape air cylinder.
␣Exposure to 6,000 ppm is immediately dangerous to life and health. If the possibility of exposure above 6,000 ppm exists, use a NIOSH approved self-contained breathing apparatus with a full facepiece operated in a pressure- demand or other positive-pressure mode equipped with an emergency escape air cylinder.
If employees are expected to fight fires, they must be trained and equipped as stated in the OSHA Fire Brigades Standard (29 CFR 1910.156).
␣Methyl Alcohol is a FLAMMABLE LIQUID. ␣Use dry chemical, CO2, water spray or alcohol-resistant
foam as extinguishing agents. ␣Water may not be effective in fighting fires. ␣POISONOUS GASES ARE PRODUCED IN FIRE. ␣CONTAINERS MAY EXPLODE IN FIRE. ␣Use water spray to keep fire-exposed containers cool. ␣Vapor is heavier than air and may travel a distance to cause
a fire or explosion far from the source and flash back. ␣Methyl Alcohol may form an ignitable vapor/air mixture in
closed tanks or containers.
