If you were hurt at an oil or gas site, a refinery or a pipeline, or lost someone there, federal agencies publish useful records: OSHA explains worker rights and complaints, the Chemical Safety Board investigates chemical accidents, and PHMSA collects pipeline incident reports. None of them decides who is legally responsible. State law usually decides that.
Most people who land on a page like this are not researching for fun. You may be home from the hospital with an injury that has stopped your paychecks, or sitting with a family member after a call no one wants to get, trying to understand what happened at the site and whether the government's investigators will answer that question for you. Many families reasonably assume an agency report will settle who was at fault. It usually does something narrower, and knowing exactly what each record is can make the weeks ahead less confusing.
This page explains what each official resource is for, where its limits are, and how it fits alongside the civil claim that state law governs.
