As a result of Robert Higgins and Kelvin Mattocks, employees of Atlantic Drain Service Co., killed on Oct. 21, 2016, when the trench in which they were working collapsed and filled with water, we were able to secure an executive order in Boston preventing contractors from obtaining permits if they have outstanding OSHA violations.

Frequently Asked Questions About Workplace Safety in Massachusetts

What does MassCOSH do?

MassCOSH is the Massachusetts Coalition for Occupational Safety and Health—a nonprofit that helps workers, unions, and communities with workplace safety through training, technical help, advocacy, and organizing. We support workers who want to understand hazards, exercise their rights, and improve conditions on the job.

How can I report an unsafe workplace in Massachusetts?

For serious hazards, workers can file a complaint with OSHA (federal) or, where it applies, Massachusetts OSHA. MassCOSH can help you think through next steps, document concerns, and find the right resource—we do not replace government enforcement. Start with Get Help if you want to talk through options.

Is workplace safety training free?

Many MassCOSH trainings and workshops are free or low-cost for workers and community members; pricing and eligibility vary by session. Check each event listing for details.

Who can get help from MassCOSH?
