If a crane comes into contact with a power line and catches fire, the rule is to jump from the cab. Is it safe to exit the cab and walk to the outrigger before jumping?
To avoid any potential danger, it's crucial not to touch both the machine and the ground simultaneously. By jumping, you stay suspended in midair, preventing any contact with both. However, the risk arises when traversing further on the machine, as this increases the chances of bridging a gap between different voltage potentials. It's safer to stick to parts securely bolted or welded, rather than risking contact with outriggers that move on greased pins. Utilizing the outrigger is a wiser choice than risking electrical hazards. It's best to swiftly distance yourself from the machine by jumping and using the outrigger, rather than bridging any potential gaps with your body.
In my humble opinion, if I were in a crane near live power lines and the crane caught fire, I wouldn't hesitate to jump out of the cab rather than try to reach the outrigger. Even if it means risking a broken leg, I believe that a broken leg is a better outcome than potential death in such a situation.
For your safety, it is crucial to remain seated and keep your hands still when near electrical equipment. Visualize concentric circles around the machine with varying levels of resistance. Jumping and accidentally touching the machine can create a dangerous circuit for electrical current to pass through. This can result in severe burns, dismemberment, or even death. NFPA 70 E training provides eye-opening videos of the consequences of such actions. It is important to update your knowledge on safety precautions, as relying on old lessons may no longer be sufficient. Despite the urge to act quickly, it is best to remain patient to avoid dangerous consequences such as sparks and power line contact.
Years ago, I recall receiving a piece of advice similar to what Jumbo mentioned. While I can't recall the source or reason behind it, at the time, I was working with a team that operated numerous excavators and a few mobile cranes. It's important to understand that the machine you are operating acts as a "Faraday cage," conducting electricity around you to the ground. In the event of a fire, the decision to either remain in the seat and risk burning or attempt to escape carries significant consequences. However, it is recommended to stay in the seat until the sparks subside, if possible. Nowadays, most hi lines are equipped with auto breakers that will shut down the system. After a brief delay, the line is pulsed to check for any short circuits to the ground. Remember the wisdom of the linemen: "If it ain't grounded, it ain't cold."
A tragic incident involving a friend losing his son in a fatal electrocution at work has brought awareness to the dangers of high voltage wires. The young man was operating a fork lift to dispose of trash when it inadvertently came into contact with the overhead power lines. Despite initially being unharmed, the fatal accident occurred when he stepped off the machine and his foot made contact with the ground. Tragically, he was identified by his dental records. This heartbreaking story serves as a reminder of the importance of safety measures in the workplace to prevent such accidents from occurring.
Answer: - Yes, it is crucial to exit the cab immediately if a crane catches fire near power lines to avoid electrocution.
Answer: - Walking to the outrigger before jumping may not be safe as the priority is to get away from the crane and power lines quickly to minimize the risk of electrocution. Jumping from the cab is the recommended course of action.
Answer: - After exiting the cab, move away from the crane and power lines to a safe distance. Stay clear of the crane and any potential hazards until emergency services arrive to handle the situation.
Answer: - Crane operators should receive proper training on how to respond to emergencies, including fires near power lines. Following safety protocols and regular drills can help operators know how to react quickly and effectively in such situations.
