How Arc Flash Analysis And Training Help Protect Employees

By Elena McDowell


Energy is highly important in every industry. Every facility must have an efficient and reliable source of energy to keep it going. Notwithstanding, the electrical system must be properly installed to keep it safe from dangers. Errors in electrical system or equipment can pose dangers to everyone around. Hence, every facility must enforce safety practices, administrative controls and appropriate arc flash analysis to reduce chances of arc flash injuries.

As defined, arc flash is an electrical explosion which typically results from low electrical impedance of another voltage phase or connection to ground of an electrical system. In other words, it occurs when current of electricity flows between separated or two energized conducting surfaces. It has been known that common causes of this to occur include human error, improper work processes, accidental contact, insulation failure and other environmental factors that lead to snapping of its connections.

In line with this, the National Fire Protection Associated established standards that ensure safety in the workplace. These standards are designed to promote safety for the personnel as well as prevent possible damages to the equipment. Therefore, it must be strictly followed in every industry.

The leading electrical industries are mandated to perform arc flash training and analysis. Every employee needs to undergo intensive training related to electrical safety. Certification is required by every state and all companies are expected to comply. This ensures that the workers understand the importance of such policies and, therefore, pledge to apply all safety procedures.

Various methods are constantly developed, tested and applied in different companies in an attempt to protect their valued assets. Thanks to the heightened awareness of the most common safety hazards. This may include proper calibration of electrical equipment, modifying existing designs and wearing of protective clothing and gears. Nonetheless, the best means of reducing electrical hazard in the workplace remains to be de-energizing of equipment during personnel interaction.

Every employee is necessary to be trained not to work on any live equipment that is more than fifty volts. However, if it is very necessary for a personnel to work on energized equipment, it is highly recommended to always observe safe work practices prior to performing the job. These safe work procedures include using proper materials, wearing appropriate protective equipment and assessing risks from the results of expert analysis of the electrical equipment.

Safe work procedure is another way of preventing injuries and issues relating to arc flash especially in the event of incident. One major precaution implemented within the workplace is following all labels and warning signs. Also, it is highly recommended that all employees should only perform the functions which they are trained and qualified.

PPE is highly essential for every electrical work as well. This training program provides the personnel with the necessary information to prepare them for the hazards at bay. This is provided to the employees to increase awareness of the equipment and materials to be used to ensure safety. The PPE may include insulating gloves, flame-resistant clothing, face shield and headgear among others.

The management team and workers alike have to understand and abide by the safety policies to prevent issues and downplay work hazards. Arc flash analysis must be performed to provide ultimate protection. Always remember that these safety measures are but a fraction of the effort in performing a job, yet its impact is sizable.
