§ 7121. Power-Driven Material Hoists.

(a) Material hoists shall not be used to hoist or lower men.

(b) Material hoists shall be installed in a safe location where falling materials from the load cannot endanger either the hoist or hoistman.

(c) Provision shall be made to prevent a pile-up of rope on the drum from overflowing the drum flange.

It is recommended that vertical roller be installed at each end of the drum to guide the incoming rope.

(d) Hands or feet shall not be used to guide the rope onto the drum. A mechanical guide may be used for this purpose, provided it is of a type that can be used safely.
