subject: Causes of Electrical Arc Flash Hazards [print this page] Arc flash is quite hazardous as it result in the emanation of very high level of electricity and heat. Getting in contact with the arc flash may get severe and abiding injury to the skin. The arc flashes are frequent in particular areas, especially where there are electric current passes from air gaps between conductors. So technicians who are engaged in handling such sort of tasks are extremely suggested to obey directions which are given in arc flash training in order to stay away from arc flash hazards. In order to prevent accidents one should undergo arc flash training.
Arc flash training is being common these days as the frequency of hazards because of arc flash are increasing day by day. Arc flash knowledge is given to every worker of the company through arc flash training so that they are aware of reason of arc flash accidents and can avoid them.
Reason of Arc Flash Accident
Likewise there are number of reasons of arc flash, but important factors that generally cause arc flash are;
* Hazardous work procedure
* Improperly designed system
* Not checking for loose terminals
* Faults at the time of maintenance
* Equipment not meeting arc flash requirement
To avoid such type of arc flash hazards now days number of organizations conduct arc flash training so that every technician and every employees are made alert of arch flash, arc flash hazards, causes of arc flash hazards and how to prevent these arc flash hazards and can protect our self from these hazards and moreover made clear the rules and regulations that are set by the OSHA and NFPA 70 codes.
To know more precisely about arc flash following are the programs that are covered under the arc flash training in order to acquire the complete information of arc flash and arc flash hazards and get rid of them;
* Gathering the data- Under this program, every required data related to the electrical equipments is gathered, such as transformer data-its impedance/voltage, Circuit breaker data, fuse data, electric utility, conductors data, etc.
* Engineering training: under this program the employees are given the training about the power system using NFPA 70E and IEEE 1584.
* Short-Circuit training: It is essential for arc flash training, management evaluation, as wel as termination analysis.
* Coordination training- It covers safety device coordination and tie- current coordination study.
* Arc flash accident hazards training- This program covers the training about the exposure related to the arc flash accident.
