Essential Facts You Need To Know About Arc Flash Analysis

Essential Facts You Need To Know About Arc Flash Analysis

By Lila Berger


On everything we do our safety is always the primary priority we should always be concern of. Accidents happen in various instances and in the most unexpected moments. We do our best to evade them but without any knowledge it will just end in vain. Therefore, it is crucial we arm ourselves with the necessary knowledge about arc flash analysis to prevent electrical accident in the future.

The blast from an electrical source which uses an oxygen as its conductor is called an arc flash. It blasts from any high voltage source that is nearby and connects to another. The electricity ignited from the explosion is able to travel the air charged to transfer to another conductor. Copper is known as the best conductor for the electricity.

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 can only provide limited shield against the explosion but it can analyze a safe buffer zone that protects the workers from exposure of the dangerous elements of the blast. This type of incidence is the leading cause of major electrical injuries and some circumstances become deadly. This easily invades the safety perimeter of any area and should be taken seriously.

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 expands very quickly thus creating a quick plasma reaction in the air that poses dangers for the surrounding. Notably, temperature reaches to extreme height that is enough to incinerate anyone from couple of feet away. The metals are vaporized leading to an explosive gas and liquefied metal flying through all directions in the air.

Companies are instructed to teach employees on the proper usage of tools when managing high voltage devices. You can easily evade any chances of burns by wearing the appropriate clothing such as cotton and other flame resistant fabrics. The incidence can be markedly lowered if the proper care of electronic devices are carried out.

The household involvement of such electrical accident is lower compared to the professional working environment. The chances for this incidence to happen is directly proportionate to the number of high voltage appliances present in the vicinity. Usually, it is always the electricians that are in danger.

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.
