Although the private sector is regulated by federal worker right-to-know laws, state employees are protected by the Worker's Right to Know Act (NH Rev. Stat. Sec. 277:A-1et seq.). Its standards are very close to those of the federal OSH Act, with a few exceptions:
Employers must make material safety data sheets available to employees for examination and reproduction upon request for each toxic substance or product mixture containing two or more toxic substances to which an employee may be exposed.
Any employee may request information about a toxic substance. If he or she does not receive such information within 5 working days, the employee may refuse to work with that substance until the employer provides the employee with the information.
