They will keep you fully anonymous but whatever you report they will send to your manager so just make sure it’s vague enough with professional writing so no one can try to pin it on you and if they do try to blame you that’s retaliation and you can sue. But they won’t find out it’s completely anonymous to your employer and tbh OSHA won’t do much physically but they’ll be on your managers ass and no company wants to be on OSHAs radar
