(b) Hoist towers shall be vertically straight.

(c) Hoist towers shall be electrically grounded.

(d) The guide rails of hoists shall be of steel securely fastened, and shall deflect no more than 1/4 -inch under normal operation.

(e) Hoist towers may be used with or without an enclosure on all sides. However, whichever alternate is chosen, the following conditions applicable to either, must be met:

(1) When a hoist tower is enclosed it shall be enclosed on all sides for its entire height with a wire-screen enclosure of not less than No. 18 U. S. Standard gage wire or equivalent material, with openings not exceeding 1/2 -inch mesh, securely fastened to the tower structure, with openings formed onto each landing.

(2) When a hoist tower is not enclosed, the hoist platform or car shall be totally enclosed (caged) on all sides, including the roof, for the full height between the floor and the cage top. The walls of the cage shall be constructed of 1/2 -inch mesh of No. 14 U. S. Standard gage wire or equivalent. The hoist-platform enclosure shall include the required gates for loading and unloading.

(f) All entrances to hoistways shall be protected by substantial gates or bars which shall guard the full width of the landing entrance.

(1) Gates shall be not less than 66 inches in height and located not more than 4 inches from the hoistway line with a maximum under-clearance of 2 inches. Gates of grille or lattice or other open work shall have openings of not more than 2 inches.

(2) Bars shall be not less than 2 by 4-inch wooden bars or the equivalent, located 2 feet from the hoistway line. Bars shall be located not less than 36 inches nor more than 42 inches above the floor.

Material hoists serving structures over 70 feet in height, or where the hoist landing platforms are not clearly visible to the hoist operator, shall be equipped with a telephone system or an electrical system or both, to assure that all gates or bars are closed before the hoist platform can be moved.

(g) Hoist towers shall be erected to a height necessary for immediate needs. However, the tower shall not be extended in height beyond the designer's recommendations and never more than 66 feet above the last (highest) guy point.

(h) An enclosure of No. 18 U. S. Standard gage wire mesh or equivalent material, which will reject a one-inch steel ball, shall be provided to prevent access into the space at the bottom of the hoist tower. The enclosure shall extend not less than 6 feet above the base of the hoist tower.

(i) Positive connections, such as those made with bolts or pins, shall join the various segments from which assembled towers are made.

(j) Diagonal bracing, or the equivalent, shall be placed on each of the four sides of the tower and between horizontal crossties, except at loading platforms, in which case bracing of equivalent strength shall be provided.

(k) Hoist towers shall only be erected and dismantled under the direct supervision of competent personnel.
