What the investigation reaches
After a serious incident, OSHA usually examines the scene, the equipment, and the work process, then requests documents such as training records, written safety programs, injury logs, maintenance records, and prior complaints. Investigators often interview employees and managers. Non-management employees can generally ask to be interviewed privately, while managers and supervisors may be treated as speaking for the company, and counsel can generally be present for those interviews. On a multi-employer worksite, such as construction, more than one company may be cited depending on each company's role in relation to the hazard. Police, insurers, and other agencies may be looking into the same event at the same time.
Responding without making things worse
Preserve the scene and the records as soon as it is safe, and suspend routine deletion of emails and messages. Do not repair or alter equipment involved in the incident until you have checked whether OSHA or other parties need to examine it. Document requests and subpoenas should be answered accurately and completely; knowingly providing false information is a serious problem on its own. Willful violations connected to a worker's death can be referred for criminal prosecution, which is rare but affects how the response is handled. Internal investigations should be structured with counsel so that their findings are protected where possible.
Citations and what comes next
If OSHA issues citations, the employer has a short period, counted in working days, to file a notice of contest, and missing it generally makes the citations final. An informal conference with the area office is often available within that window and can lead to a settlement. Contested citations go to the Occupational Safety and Health Review Commission, an independent agency. Contesting a citation generally pauses the deadline to correct the contested items, but fixing the hazard promptly is still wise, and documenting that work matters. A civil lawsuit by the injured worker or family may follow, though workers' compensation usually limits claims against the employer itself.
