High-voltage electricity carries inherent risks. These hazards are not just confined to severe injuries or death from electric shock; they can also cause burns, falls, fires, and explosions. Below are some of the most common dangers associated with high voltage: 1. Electric Shock
How much voltage is dangerous is not really a static number as it depends on your body resistance, time of exposure and source "stiffness" (i.e. how much current it can supply). You get figures like 60V (or as low as 30V) which are an attempt at an average figure above which "caution should be taken".
It's not the voltage but the current that kills, is a popular yet still incorrect incomplete answer. It is the ENERGY that kills. With static electricity you will will be exposed to voltages much, much, much higher than 110/230V and that is not dangerous. So obviously high voltages are not that dangerous in some cases. Why?
Electrical current will cause muscles to contract and can lead to respitory and cardiovascular seizures. The electrical energy imparted on the body will burn and cause serious internal injury. But this only holds true for a given voltage, a certain voltage is needed to traverse the skin and this of course is a function of the impedance.
However, strict safety measures are necessary when working with or near high-voltage systems due to their associated hazards. High-voltage electricity carries inherent risks. These hazards are not just confined to severe injuries or death from electric shock; they can also cause burns, falls, fires, and explosions.
Working with high voltages, however, can present some dangers that can cause serious injury if ignored. In this article, we will take a look at the dangers associated with high voltages that could cause injury and some things to be aware of whilst working with high voltages. We will start by defining what is meant by the term high voltage.
