Arizona Revised Statutes Title 27. Minerals, Oil and Gas § 27-351. Hoists; operator; indicator

A. No person addicted to intoxicating liquors or drugs, or under eighteen years of age shall be employed as a hoisting engineer.

B. All power hoisting machinery used in hoisting from or lowering employees and materials into mines, except for prospect shafts not exceeding three hundred feet in depth, shall be equipped with an indicator placed near and in clear view or hearing of the engineer. The indicator shall be in addition to marks on the rope, cable or drum.

C. It is unlawful to hoist or lower persons from or into a mine at a speed greater than fifteen hundred feet per minute, but the inspector may designate a lesser speed than fifteen hundred feet per minute in a shaft, if in his opinion a greater speed is unsafe, or a greater speed if in his opinion particular shafts and hoist conditions so warrant.
