Section 43.39 - Sanitation

(a) It shall be the duty of the constructor of every tunnel, for the purpose of improving sanitation and preserving the health of those employed, to provide dry closets, water closets, chemical closets, or closet cars upon all main working levels for the use of all men employed in the tunnel. At least one closet shall be provided for every 40 men employed within the tunnel. Ready means of access to each closet shall be provided by the constructor. No closet shall be constructed without adequate provision for its effective cleaning. The contents of the closet shall be removed and disposed of at least twice a week. The tunnel foreman shall cause each dry closet to be supplied with some disinfectant or deodorizer to be sprinkled upon its contents. All men employed within the tunnel where such closets are provided shall use the closets exclusively when in the tunnel. This requirement shall not apply to any tunnel where the constructor or superintendent prefers to permit the men to go to the surface and requires the men to do so.

(b) Every stable or other place underground used for the housing of mules, horses or other animals, shall be kept thoroughly clean and the waste contents removed to the surface.

(c) The constructor of every tunnel shall provide a sufficient quantity of good drinking water for the use of all men employed in the tunnel. A supply shall be provided on each main working level. The superintendent shall insure that the drinking water is adequately protected from contamination.

(d) The constructor of every tunnel employing more than 25 men underground shall provide a wash and change house. It shall be adequately heated and lighted and shall contain a sufficient supply of running water, hot and cold showers, washbowls and lockers.
