(2) An escape hatch shall be provided where doors on an enclosed cab provided on a powered industrial truck may be blocked by special equipment. (3) A crane, powered industrial truck, or other wood handling equipment, except over the road vehicles, having a cab with windows shall have all windows protected by a screen made of steel rods not less than 7/16 inch in diameter with openings not more than 4 by 4 inches or 2 by 6 inches. (4) Where a hooker or hatch tender is used, the operator of a cab style crane shall respond to the hooker’s or hatch tender’s signals. The signals for an overhead crane shall be as prescribed in Table 1 ‘Standard Hand Signals for Controlling Overhead and Gantry Cranes.’ The signals for a boom type crane shall be as prescribed in Table 2 ‘Hand Signals for Boom-Type Cranes.’ (5) A blower used to transport rags shall be provided a feed hopper with the opening not less than 48 inches from the fan. The blower outlet must not allow material to fall on an employee. (6) Railroad cars shall not be spotted on tracks adjacent to the locomotive cranes unless a 24-inch clearance is maintained, as prescribed in R 408.16342(1). (7) The handling and storage of other materials shall conform to R 408.16342(1) and (2) with respect to clearance. (8) Handles of wood hooks shall be locked to the shank to prevent them from rotating. (9) An employee shall not ride on a powered hand truck unless it is so designed by the manufacturer. A limit switch shall be on the operating handle —30 degrees each way from a 45-degree angle up and down beyond which the drive motor is electrically disconnected and braking action commences. (10) Whenever possible, all dust, fumes, and gases incident to handling materials shall be controlled at the source, in accordance with ANSI Standard Z9.2 “Fundamentals Governing the Design and Operation of Local Exhaust Ventilation Systems,” 1960 edition, as adopted in R 408.16302. Where control at the source is not possible, an employer shall provide respirators with goggles or protective masks, and employees shall wear them when handling alum, clay, soda, ash, lime, bleach powder, sulfur, chlorine, and similar materials, and when opening rag bales. (11) Hoods of cutters, shredders, and dusters shall have exhaust ventilation in accordance with ANSI Standard Z9.2 “Fundamentals Governing the Design and Operation of Local Exhaust Ventilation Systems,” 1960 edition, as adopted in R 408.16302. TABLE 1 STANDARD HAND SIGNALS FOR CONTROLLING OVERHEAD AND GANTRY CRANE HOIST. With forearm vertical, forefinger pointing up, move hand in small horizontal circle. LOWER. With arm extended downward, forefinger pointing down, move hand in small horizontal circles. BRIDGE TRAVEL. Arm extended forward, hand open and slightly raised, make pushing motion in direction of travel. TABLE 1 STANDARD HAND SIGNALS FOR CONTROLLING OVERHEAD AND GANTRY CRANE TROLLEY TRAVEL. Palm up, fingers closed, thumb pointing in direction of motion, jerk hand horizontally. STOP. Arm extended, palm down, hold position rigidly. EMERGENCY STOP. Arm extended, palm down, move hand rapidly right and left. MULTIPLE TROLLEYS. Hold up one finger for block marked “1” and two fingers for block marked “2”, Regular signals follow. MOVE SLOWLY. Use one hand to give any motion signal and place other hand motionless in front of hand giving the motion signal. (Hoist slowly shown as example.) MAGNET IS DISCONNECTED. Crane operator spreads both hands apart – palms up. TABLE 2 HAND SIGNALS FOR BOOM-TYPE CRANES HOIST. With forearm vertical, forefinger pointing up, move LOWER. With arm extended downward, forefinger pointing USE MAIN HOIST. Tap fist on head; then use regular signals. TABLE 1 STANDARD HAND SIGNALS FOR CONTROLLING OVERHEAD AND GANTRY CRANE hand in small horizontal circle. down, move hand in small horizontal circles. USE WHIPLINE. (Auxiliary Hoist). Tap elbow with one hand; then use regular signals. RAISE BOOM. Arm Extended, fingers closed, thumb pointing upward. LOWER BOOM. Arm extended, fingers closed, thumb pointing downward. 7 MOVE SLOWLY. Use one hand to give any motion signal and place other hand motionless in front of hand giving the motion signal. (Hoist slowly shown as example.) RAISE THE BOOM AND LOWER THE LOAD. With arm extended, thumb pointing up, flex fingers in and out as long as load movement is desired. LOWER THE BOOM AND RAISE THE LOAD. With arm extended, thumb pointing down, flex fingers in and out as long as load movement is desired. TABLE 1 STANDARD HAND SIGNALS FOR CONTROLLING OVERHEAD AND GANTRY CRANE SWING. Arm extended, point with finger in direction of swing of boom. STOP. Arm Extended, palm down, hold position rigidly. EMERGENCY STOP. Arm extended, palm down, move hand rapidly right and left. TRAVEL. Arm extended forward, hand open and slightly raised, make pushing motion in direction of travel. DOG EVERYTHING. Clasp hand in front of body. TRAVEL.(Both Tracks) Use both fists in front of body, making a circular motion about each other, indicating direction of travel, forward or backward. (For crawler cranes only.) TRAVEL. (One Track.) Lock the track on side indicated by raised fist. Travel opposite track in direction indicated by circular motion of other fist, rotated vertically in Extracted from American National Standard, Safety Code for Crawler, Locomotive and Truck Cranes, B 30.5-1968 with the permission of the publisher, The American Society of Mechanical Engineers, United Engineering Center, 345 East 47th Street, New York, N.Y. 10017.
