The Bureau investigates violations of standards, orders, or special orders in which there has been a fatality or a serious injury or illness. The Bureau also directs investigations when DOSH's civil compliance staff makes a request for prosecution. For any case in which the Bureau is required to conduct an investigation and in which serious injury or death has occurred, the Bureau refers the results of the investigation to the appropriate prosecuting authority with jurisdiction over appropriate action, unless the evidence of a violation of the law is insufficient.
