W. Va. Code § 22A-2-17: Ascertainment, record and removal of all dangers.

The mine foreman shall give prompt attention to the removal of all dangers reported to him by his assistants, the fire boss or any other person working in the mine, and in case it is impracticable to remove the danger at once, he shall notify all persons whose safety is menaced thereby to remain away from the area where the dangerous condition exists. He or his assistants or certified persons designated by him shall at least once each week travel and examine the air courses, roads and openings that give access to old workings or falls and make a record of the condition of all places where danger has been found, with ink or indelible pencil in a book provided for that purpose.
