NOTE: The principal hazards of all shaft work are falls of persons; falling materials, including rock from operating skips and skip pockets; and skips in adjoining compartments which may strike workers or materials being handled.

NOTE: The hazards of falling persons and falling materials decrease as the incline of the shaft grows flatter, but a fall in a 20 degree shaft may cause painful or even serious injury.
