Essential Facts You Need To Know About Arc Flash Analysis

By Lila Berger


Accidents happen in the most unlikely places and they are always unexpected. On a technology driven world, the presence of electrical circuit that powers our individual lives are susceptible to these types of accidents as well. This poses a safety hazard for anyone exposed to this circuit and that is why a comprehensive arc flash analysis is necessary to give advantage to the safety for anyone.

Arc flash is a discharge of electricity that results from a high voltage source. It uses the oxygen that is abundant all around to power itself for the explosion. The electricity that is released in the air can easily chain itself to another exposed electrical devices that are within the area.

The crack in the system happens quickly and often produces intense heat and massive amount energy. It is highly capable of liquefying the metals and electric circuits nearby. This in turn produces extreme temperature that is known to hotter than the external part of the sun as the experts suggested. It is then capable of producing plasma that transports hazardous electromagnetic radiation, shrapnel and some troubling sound waves.

Hazard analysis provides not much defense against the blast itself but it does provide a buffer space which guards any workers from the flash. Arc flashes are hazardous to anyone nearby and are known to be responsible for many electric injuries and even deaths. This poses a real threat to the safety for those around the area.

This occurrence only happens when there is high voltage conductor nearby. Corrosion, accidental gaps in insulation and unintended static electricity are the factors that contribute for the air to enter the system and serve as a conduit for an explosion. Since this is a powerful burst of energy it needs a lot of power, around 600 volts or higher, to make the blast possible.

The energy is capable of expanding so quickly that it creates a rapid plasma reaction with the oxygen present all around which poses tremendous danger to the surrounding structures. It has been observed that due to the extreme rise of the temperature it is capable of scorching anyone that is positioned for a several feet away. Vaporization of metal is highly possible which causes explosive hot gases and melted metal to fly in any directions.

The incidence can be greatly lowered by taking proper care of handling electronic devices and wiring. Burns can be prevented as well by wearing cotton and any fire resistant clothing. This can be prevented with proper knowledge and safety procedures in handling high voltage devices.

The chances that it occurs in your home is very slim not unless you are using high voltage devices. This is common in professional working place and construction sites. The danger it poses are usually in electricians and those who are involve in installing these devices.

The primary responsibility of arc flash analysis is measuring the danger level of an area exposed to the factor above. They do everything they can base on the information they gathered to set up a buffer zone that protects everyone from the threat. They are very indispensable on this principle.
