The four main causes of crane accidents are contact with power lines, overturns, falls and mechanical failure. Each year nearly 200 people die from power line contact and about three times as many are seriously injured. Likewise, suspended loads should never be moved over employees and personnel should never be lifted or transported on a hoist. Your email address will not be published. Most victims are guiding the load at the time of contact, but risks extend to everyone present at a job site. When installed and used properly, these systems make operations easier and safer. General safety principles that can help reduce workplace accidents include: 7. OSHA 1926.1424 is designed to protect employees who work near a crane from being struck or crushed by the crane's rotating superstructure. Preventing these disasters requires workers to recognize certain hazards that occur during operation and follow safety procedures to avoid them. As a result, San Francisco alone has seen more than a 24% increase in office vacancy. According to OSHA, nearly 50 percent of overhead crane accidents are the result of machinery coming into contact with a power source during operation. 4.

Everyone associated with a crane needs to stay alert and focused on the job at hand - especially on critical or difficult lifts. Nearly 80 percent of these upsets can be attributed to predictable human error when the operator inadvertently exceeds the cranes lifting capacity. Maintenance should always be treated seriously when it comes to heavy machinery. Typically, stacker cranes are used in places with special working conditions, like extremely cold temperatures, making it unnecessary for a human worker to endure extreme working conditions.

(Your Answer). Approximately 75 percent of struck-by fatalities involve: Heavy equipment, such as trucks or cranes (Your Answer). Using fall protection in an industrial crane environment can create many potential hazardsincluding crane contact, structural impact, entanglement, and dragging. Reduce the Chances of Fatalities: Properly outline fall zones with barriers. Operators should also maintain a safe speed when operating near power lines. When manually moving materials, employees should always try to lift it alone if a load is so bulky it cannot be properly grasped or lifted, when they cannot see around or over it, or when a load cannot be safely handled.
