Accidents; notice to commission; investigations

Every common carrier and every public utility governed by the provisions of this act, whenever an accident attended with loss of human life or serious personal injury occurs upon its premises within this state, shall give immediate notice thereof to the commission by telegraph, telephone or telecopy. If notice is given by telephone, such notice shall be followed by a written notice sent by certified or registered mail. In the event of any such accident, if the commission determines that the public interest requires an investigation to be made with the secretary of labor, such investigation shall be held in the locality of the accident, unless for greater convenience of those concerned, the commission orders such investigation be held at some other place. Such investigation may be adjourned from place to place as may be found necessary and convenient. The commission shall notify an officer or agent of the public utility or common carrier of the time and place of the investigation in a timely manner.
