28--Elevators and Plant Railways side and limits the sum of the clearances on the two sides to M in, unless skirt switches are installed The Elevator Code requires that each balustrade have a handrail moving m the same direction and at substantially the same speed as the steps Each moving handrail is to extend at normal handrail height (not less than 12 in beyond the points of the combplate teeth at the upper and lower landings) Hand or finger guards are to be provided at the point where the handrail enters the balustrade In some localities, barefoot passengers have been injured, and signs warning bare foot persons not to ride the escalator have been posted Umbrella tips frequently are caught between the grooves and the combplate, and this type of accident occasionally results in minor injuries and in damage to equipment Many accidents have resulted from attempts to handle baggage on escalators Suitcases and handbags should not be placed on the steps and, if earned by hand, always should be held parallel to the run of the escalator Escalator treads and landings should be of incombustible material affording secure foot hold.

Low-Cost Universal Barrier Guard The upper guard is positioned on the die with the aid of a ram template Press guarding is simplified by designing universal barrier guards The finished guard is made in two sections that completely enclose the danger zone The upper guard will enclose any operation done on the press, the lower guard conforms to the upper guard, the feed device, and the lower die contour An opening, standardized to the widest feeding arrangement anticipated, is now made in the upper guard This will allow flexibility of the upper guard in all press operations of similar size '/,-in diameter steel rods are spot welded (7/-in center-to-center) on a frame made of 3/a-in diameter steel rods Height should be sufficient to cover the ram at the top of the stroke The design of the lower guard is made to conform to the upper guard, the feed device, and the lower die contour The framing and webbing are angled or bent to permit easy loading and eliminate finger entry into danger zone 875
