According to OSHA, nearly 50 percent of overhead crane accidents are the result of machinery coming into contact with a power source during operation. -- Whenever a new hazardous chemical is introduced into their work area. Slings and attachments that arent secured properly can be a major safety hazard, and when objects begin to slip, they will eventually crash to the floor below. Erect and maintain control lines, warning lines, railings or similar barriers to mark the boundaries of the hazard areas. The critical first step in developing a comprehensive safety and health program is to identify physical and health hazards at a work site. When dismantling a scaffold, all work should be conducted: 6. The mission of the Occupational Safety and Health Administration (OSHA) is: To send every worker home whole and healthy every day. If a moving part on an overhead crane wears out or breaks the hoist, it can cause serious damage. Visual impairment, two-blocking, slipping, mechanical failure, or operator incompetency can all result in serious injuries or fatalities. Cranes should be positioned such that the boom or bucket cannot be swung over employees.

Crane signalmen keeping crane operators informed when anyone is within the cranes swing radius and stopping operations until clear. When a store has a sale, it cuts the prices on the goods it sells. Furthermore, cranes should be kept away from unsafe working areas; OSHA and ANSI both outline safe distances operators must maintain from a power source when working at a job site. Hazards related to this job Specific preventive measures can be seen by clicking on the respective in the third column of the table. The duties of a crane operator involve many responsibilities. Workers should be trained to stay clear of the hoist, and they should never walk beneath loads suspended in the air.
