Likewise, suspended loads should never be moved over employees and personnel should never be lifted or transported on a hoist. Ensure the load is properly balanced and secured before the crane lifts it. Providing worker training on the safe use of the equipment being operated is the responsibility of the: 7. Here are some duties of a crane operator: The operator must not leave the controls while the load is suspended except where ALL of the following criteria are met: The four criteria immediately above do not apply to working gear (such as slings, spreader bars, ladders, and welding machines) where the weight of the working gear is negligible relative to the lifting capacity of the equipment as position, and the working gear is suspended over an area other than an entrance or exit. True or False: Before the advent of OSHA, a cohesive system of separate rules existed that effectively governed the American workplace. The area within a 10-foot radius of a power line is considered an unsafe work areaor danger zoneand it must be clearly marked on the ground by insulated barriers, fences, tape, etc. Establish communication with ground personnel and confirm understanding of signals before proceeding. Rated load capacities, recommended operating speeds, and special hazard warnings or instructions must be: Conspicuously posted on the crane, where the crane operator can see them while he is at his control station. As mentioned in this module, in addition to cave-ins and related hazards, workers involved in excavation work also are exposed to hazards involving: Falls, falling loads, and mobile equipment (Your Answer). To provide a safe environment of work and to ensure compliance with current legislation and relevant Occupational Health and Safety (OH&S) measure crane lifting safety Procedure has been developed and is to be implemented by every member of the bridge construction team involved in lifting operation. Visual impairment, two-blocking, slipping, mechanical failure, or operator incompetency can all result in serious injuries or fatalities. When dismantling a scaffold, all work should be conducted: Tube and coupler scaffolds over 125 feet high must be designed by: What type of scaffold - other than the tube and coupler scaffold - is ideal for use around complex structures?
