Section 200 - General duty to protect health and safety of employees; enforcement1. All places to which this chapter applies shall be so constructed, equipped, arranged, operated and conducted as to provide reasonable and adequate protection to the lives, health and safety of all persons employed therein or lawfully frequenting such places. All machinery, equipment, and devices in such places shall be so placed, operated, guarded, and lighted as to provide reasonable and adequate protection to all such persons. The board may make rules to carry into effect the provisions of this section.2. If the commissioner finds that any machinery, equipment, or device in any place to which this chapter applies is in a dangerous condition, or finds that any area to which this chapter applies is in a dangerous condition, he may attach a notice to such machinery, equipment, or device, or post a notice in such area warning all persons of the danger. Such notice shall prohibit the use of such machinery, equipment, or device or prohibit further work in or occupancy of such area until the dangerous condition is corrected and the notice is removed by the commissioner.

The board shall grant or deny such application for a stay within seventy-two hours after the filing of the application.3. Whenever a notice is attached or posted as provided in subdivision two of this section, the attorney general may institute a proceeding to enjoin the use of such machinery, equipment, or device or to enjoin further work in or occupancy of such area. Such proceeding shall not be stayed by the filing with the board of a petition for a review of the validity or reasonableness of a commissioner's order pursuant to section one hundred one of this chapter.4.
