I work with a substance that I think may be hazardous?

Massachusetts has a "Right to Know" law, MGL c. 111F, dealing with hazardous material in the workplace. Employers must meet certain obligations, including labeling of containers, posting of information, and training of workers. Employees have the right to request from the employer a Material Safety Data Sheet, which will include the properties of the hazardous material and how to handle them. For more information on the Right to Know Law, hazardous chemicals, Asbestos, or general information on workplace safety, call the Attorney General, 617-727-3465.
