OP, Go to osha.gov. Everything is there to file a complaint/report a safety violation or condition. They expect this to be done as soon as you are aware of a violation. There are online forms and you can also start by calling OSHA at 800-321-OSHA and talk to someone. See the FAQ on the OSHA website.
You will not get any compensation through OSHA or in any civil case without proof of injury. *This is not legal advice, only website advice.
