Course Overview

Arc flashes are known as one of the deadliest electrical hazards because they are sudden, explosive releases of energy that cause many injuries every year. An arc flash may occur when conductive objects are placed near unprotected conductors. Abandoned tools may also trigger sparks that may start arc blasts.

People who are expected to work with or near arc flash hazards must be aware of the risks involved and the things they need to do in order to protect themselves. Arc flash safety measures also refer to the importance of examining old electrical tools with bad parts or worn out wires which can be unsafe because of the extreme degrees of temperature it generates.

When the electrical current leaps, this may also trigger extremely bright flashes of light that can damage exposed eyesight. Each region has its own regulatory body that outlines electrical safety requirements for the overall construction industry and its activities to minimise the risk of electricity-related damages and accidents.

This ARC Flash Electrical Safety, Protection and Hazard training course will highlight the significance of arc flash electrical safety with reference to shock hazards, incident energies, limits of approach, burns, personal protective equipment, and arc flash mitigation strategies.

Companies that employ electrical workers are usually required to conduct an arc flash analysis to evaluate the amount of thermal energy that can be produced within the environment. The results of this analysis will determine the amount of heat-resistant clothing that they should provide their workers.

What topics will this “ARC Flash Electrical Safety, Protection and Hazard” discuss? Overall, this training program will take a look at the causes of arc flash and its probable effects, arc flash protection boundary, incident energy calculations, the importance of warning labels, the use of PPE, and other safety requirements.

This Zoe training course will empower you with a deep understanding of the causes of arc flash incidents and calculation of incident energies, along with the various techniques to ensure arc fault safety.
