The document discusses the structure and procedures of OSHA inspections. It explains that there are four types of inspections based on priority, and describes the onsite inspection process. This includes presenting credentials, opening and closing conferences, employee interviews, and the issuance of citations classifying violations as willful, repeat, serious, failure-to-abate, or non-serious/other than serious. Employers have options to comply with citations, request an informal conference, or notice of contest.
