52 Pa. Stat. § 70-711
Handrails and efficient safety catches shall be attached to, and a sufficient cover overhead shall be provided on, every cage used for lowering or hoisting persons in any shaft. The operator or superintendent of all mines shall see that the surface landing, and all other landings, of shafts are, so far as practicable, provided with gates, controlled in such a fashion that they cannot be opened except when the shaft carriage is at that particular landing. Such gates, before being used, shall be first approved by the mine inspector. It shall be unlawful for any man, employed as a footman or headman at a shaft hoisting coal or other material, to work at this occupation, unless he has provided himself with a safety headgear or helmet of a design approved by the Department of Mines and Mineral Industries, which headgear or helmet must be worn by him at all times while on duty.
