Every complex electrical installation is potentially at risk of suffering an arc flash due to the dangerous interplay of energy and power within its components. According to the HSE, about 60,000 cable strike electrical accidents happen annually in the United Kingdom. Many of these result in arc flashes and cause approximately 25 deaths yearly.
An arc flash explosion can generate an extreme heat of up to 19,427 °C. This heat is four times hotter than the sun's surface! It is dangerous to electrical engineers and potentially hazardous to other construction workers, passers-by, and the property.
This piece will elaborate on the causes and why you should implement arc flash prevention practices when working on electrical systems.
