The risk of electrocution is largely due to the possibility that the fault line may still be charged and the current will form a circuit through the body. It's not a small matter, but the effect of the circuit, when you break into the restricted area after it's "danger alert" -- the jump means that the circuit or electrical insulation, the environmental damp triggers a power leak, and then the “repeat button” on the electrical protection switch will eject automatically。
Electricity exposure: currents reaching the human body
The failure point may not have been completely out of power after the breakout. If the line is still electric or the switch itself is insulated, the current will pass directly through the human body when it is touched by bare hands. More crucially, if the body becomes a conduit, even small currents can disrupt the normal rhythm of the heart. Reference is made to a warning from the fire department that this electrocution may cause a cpr or even cause a cardiac arrest in a short period of time。
Imagine the current, like an invisible snake, hitting your heart straight through your arm — not a scare, but a warning based on a real accident. The leak protection was originally designed to cause a rapid power outage when the leak was detected above the safety threshold (e. G. 30ma), but to close the gate if the hazard was not removed after the jump would be tantamount to removing the lifeguard。
Arc burns and secondary injuries
In addition to direct access to electricity, hand-to-hand gates may trigger a more hidden risk. If the jumper is caused by short-circuit failure (e. G. Direct contact between the fireline and the zero line), it produces thousands of degrees of high-temperature arcs. The temperature of this “electric fire” is much higher than that of the day-to-day flame, allowing instant burns to the hand, face and even eyes, leaving permanent harm. But the problem is that the arc does not warn in advance, it only explodes at the moment when the gate is closed。
An electrical or arc shock also triggers a chain reaction: muscle spasms may prevent you from unlocking the switch or falling out of shock. If the battery is installed at a height, the fall may cause a break, bump and other secondary injury. These indirect risks are often ignored and are equally threatening to life. After all, the circuit failure is like an unexploded mine, and the hand-to-hand gate is a hand-to-hand trigger。
Secure the gate. Three steps
In case of a leak, the correct approach is not to push, but to remove the risk. Safety operations can be summarized as three steps, and it is imperative that insulation tools be used throughout the process and that no use be made by hand。
The circuit breaker is an important security early warning mechanism for the electrical system, and it is only safe if it is respected。
