Some MA cities and large GCs require a photo worker ID and proof of OSHA training before you set foot on the site. Not a state-wide credential, but common on Boston-area commercial jobs.

Who needs it

Anyone working on a large commercial or public-works site in Greater Boston.

How to get it

Issued by the GC or general contractor's safety office once you provide your OSHA card and ID. Some sites require pre-task hazard training on top.

Cost

Usually free — the GC handles it.
