(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 shall not allow material to fall on an employee.

(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, respirators with goggles or protective masks shall be provided, and employees shall wear them when handling alum, clay, soda, ash, lime, bleach powder, sulfur, chlorine, and similar materials, and when opening rag bales.

TABLE 1 STANDARD HAND SIGNALS FOR CONTROLLING OVERHEAD AND GANTRY CRANE
Hold up one finger for block marked “1” and two fingers for block marked “2”, Regular signals follow.	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.)	DISCONNECTED. Crane operator spreads both hands apart – palms up.

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.	USE MAIN HOIST. Tap fist on head; then use regular signals.
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.

TABLE 2 HAND SIGNALS FOR BOOM-TYPE CRANES
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.
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,	DOG EVERYTHING. Clasp hand in front of body.	TRAVEL. (Both Tracks) Use both fists in front of body, making a circular motion
