The world is littered with accidents occurring in the most unexpected places. The advancement of technology aids from the safety hazards that we are exposed to everyday. Therefore, we should educate ourselves about arc flash analysis to avoid any unwanted occurrence cause by electrical instability.



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.



This happen so quickly and causes a large amount of heat that melts any metal around and destroys the electrical equipment. Some even reported that heat sometimes achieve a temperature hotter than the surface of the sun. It can even produce plasma wherein shrapnel, dangerous sound waves and high electromagnetic radiation goes with the explosion.



Furthermore, this makes it a complete safety hazard for anyone in the area. The analysis provides little protection to the people against such risks but it does provide a buffer zone that guards workers from the heating effect of the flash. This occurrence is responsible to numerous electrical injuries and some even resulted to death.



This incidence will only be possible with the involvement of a high voltage conductor as the source. There should be an error in the system that causes the air to enter inside and act as a conduit for the blast. Since intense amount of power is needed because so much energy is involved, it is commonly seen in six hundred volt or higher.



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.



Prevention of this to happen is the goal of every company that is susceptible that is why it is required that every employee knows the precautions of high voltage devices. Wearing cotton or other fabrics impervious to fire. The only known way to lessen the incidence is through proper knowledge in caring for such 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.



Arc flash analysis measures the danger level of this incidence and how much it can affect anyone. The incident is carefully calculated regarding the needed energy for the blast to cause second degree burn. They also establish flash protection boundary where they set a safety zone from the blast. It is beneficial in so many ways for the workers to have a clear idea of where it is safe and where it is not.
