We do not permit lifting of loads using the bucket teeth of an excavator or by hanging rigging across the bucket. But we often use the excavator lifting point, a hook mounted on the bucket, to lift loads around the site. Create a Safe Work Practice (SWP) for lifting loads with the lifting point of an excavator bucket. Include all the usual requirements for safe lifting as they pertain to rigging and lifting device condition. One of the main concerns is that the hook, regularly makes contact with the earth, during digging and other excavator operations, so we cannot guarantee the condition of the hook beyond a good visual inspecting. Even NDT testing would be invalid if the hook were to be used in a digging capacity and made contact with the earth.

# How should you inspect the internal parts of the clamp? (cont.) ## How should you use plate clamps safely? (cont.) - Use two or more clamps to balance a long or flexible load. - Install the clamp (or clamps) over the centre of gravity of the plate. - When using a vertical type of plate clamp, use a locking device to prevent accidental loosening. - Use horizontal types of plate clamps in pairs. - Use clamps within their rated capacity and flange width. - Lock a clamp closed before lifting a load. - Use a sling between the clamp and the crane or hoist hook. - Use non-marring (rubber pad) clamps in pairs when lifting finished and polished plates. - Lift smoothly; avoid jolts. - If the use of a tag line is necessary, attach it to the clamp before lifting the plate. Locking Device (prevents accidental loosening) Use in Pairs ## What should you avoid when using plate clamps? - Do not lift over workers. - Do not stand near a load. - Position yourself away from and fully clear of the load. Remember to also consider how the load might fall when it lands. Materials Handling - Plate Clamp Inspection and Use CCOHS

(6) The total weight of the lifted load, including rigging, plat- form, personnel, tools, and material must not exceed 50% of the crane's rated capacity for the radius and configuration, under the planned conditions of operations (except during testing as outlined in WAC [redacted identifier]). (7) When the occupied personnel platform is in a stationary work- ing position, the load and boom hoist brakes, swing brakes, and opera- tor actuated secondary braking and locking features (such as pawls or dogs) or automatic secondary brakes must be engaged. (8) The employer must inspect the area where the crane/equipment will be set up and look for: (a) Overhead obstructions; (b) Electrical lines; (c) Hazardous locations; (d) Inadequate surface area; (e) Inadequate support to withstand all force imposed, wind, weather, and unstable conditions; and (f) Other potentially hazardous conditions. (9) Hooks on headache ball assemblies, lower load blocks, or oth- er attachment assemblies must be of a type that can be closed and locked, eliminating the hook throat opening. Alternatively, an alloy anchor type shackle with a bolt, nut and retaining pin may be used. [Statutory Authority: RCW 49.17.010, 49.17.040, 49.17.050, 49.17.060, and chapter 49.17 RCW.

# Struck by concrete forms-Insp # 1602868 Lee Company A choker hitch only compresses the load on 3 sides whereas a double wrap choker hitch compresses the load on all 4 sides providing better load control. New formwork is extremely slippery by design to prevent concrete from sticking to it and loses its non-stick qualities with use; the formwork that struck the victim was new and had never been used before. Without rigging that provided compression from all 4 sides the slippery load was able to move in the single wrap choker hitch displacing the load and ultimately dumping the load below. The rigger did not communicate a safe route and exposed employees to the hoisted load as it traveled directly over them as they worked on the 31st floor. No citations were issued to this employer; however, citations were issued to Harcon, Inc. ## Citation(s) as Originally Issued A complete inspection was conducted at the accident scene. Some of the items cited may not directly relate to the fatality.

CPWR TOOLBOX THE CENTER FOR CONSTRUCTION RESEARCH AND TRAINING # Lifting and TALK Carrying Materials Back injuries are caused by lifting and carrying heavy materials, working in awkward positions, and bending often to lift materials off the ground. Construction has one of the highest rates of back injuries of any industry. ## Jeff's Story Jeff worked on a masonry crew at a construction site. Over the course of a day, Jeff and his crew moved 200 30-pound bags of concrete from the delivery location to the work area by hand because they thought it would take less time than finding a cart or forklift to do the job. His back began to bother him, but he wrote it off to just being part of the job. The next day the pain became so bad that he had to leave work and see his doctor. They told Jeff that he had damaged a disc in his lower back and could no longer do that kind of work. * Have you or someone you know ever had a back injury from lifting and carrying? If so, what happened? - How could the injury have been prevented? ## Remember This ➤ Whenever possible, use mechanical equipment like a dolly to move heavy objects horizontally. ➤ Never try to lift an item weighing over 50 pounds by yourself. ➤ Plan your lifts; make sure the path is clear and you are facing the direction of travel before lifting. ➤While lifting, tuck in your chin to keep your neck straight, and keep your back as straight as possible. - Lift with the leg muscles, which can help protect your back. ➤ Ask for help with heavy or awkward objects. ➤ Avoid twisting your body while carrying an object. ➤ Coordinate and practice team lifting before using it for moving objects. How can we stay safe today? What will we do at the worksite to prevent being injured from lifting and carrying? 1. 2.
