When, in the opinion of the division, a place of employment, machine, device, apparatus, or equipment or any part thereof is in a dangerous condition, is not properly guarded or is dangerously placed so as to constitute an imminent hazard to employees, entry therein, or the use thereof, as the case may be, shall be prohibited by the division, and a conspicuous notice to that effect shall be attached thereto. Such prohibition of use shall be limited to the immediate area in which the imminent hazard exists, and the division shall not prohibit any entry in or use of a place of employment, machine, device, apparatus, or equipment, or any part thereof, which is outside such area of imminent hazard. Such notice shall not be removed except by an authorized representative of the division, nor until the place of employment, machine, device, apparatus, or equipment is made safe and the required safeguards or safety appliances or devices are provided. This section shall not prevent the entry or use with the division’s knowledge and permission for the sole purpose of eliminating the dangerous conditions.
