An arc flash is amongst the most dangerous electrical risks that organizations face at the workplace, and these events may lead to life threatening effects, immense property loss and even deaths. An arc flash is defined as an electrical current that appears as a spark between conductors, causing heat, light and pressure that can harm anyone and anything in its reach.
Because the impacts can be so dire, employers must take special precautions when it comes to safety and security on the job site. One of these is an arc flash study that is intended to assess hazards, determine the level of the incident energy and suggest measures to be taken. It is important for staying in line with the safety requirements of the industry and providing a safe workplace with a protection level that is ready for anything.
What Is Arc Flash Analysis?
Arc flash hazard risk assessment is a safety evaluation process to find out most possible arc flash hazards and levels of energy in electrical circuits. This assessment enables the facility to incorporate the right degree of protection for various equipment, reducing overall risk. Arc flash studies help to identify safe approach limits, the gear required for protection, and circuit safety requirements—with a view of reducing accidents.
This calculation is often done by seasoned electric engineers; they observe traits such as the condition of equipment, fault currents, and configurations of the system. They estimate potential incident energy levels and also recommend measures to eliminate arc flash risks, including system improvements, design modifications, and/or labels.
Why It Is Crucial to Have Arc Flash Analysis in The Workplace
a. Protecting Workers from Severe Injuries
An arc flash encounter is likely to have serious consequences, or even be fatal, with the risk of serious skin burn injuries, respiratory problems, etc. An arc flash analysis exposes potential hazards and helps with the setting up of safety measures that will help to minimize or prevent such mishaps.
b. Establishing Safe Working Conditions
An arc flash analysis assists in creating a secure working perimeter for individuals who may have to work on maintaining electrical systems—by identifying safe working distances and PPE. The analysis offers employees guidelines concerning protective apparel and restricted areas, significantly increasing safety.
c. Preventing Costly Equipment Damage
Arc flash accidents lead to very costly equipment breakdowns to the extent of requiring replacements, and there are lengthy periods of inoperability. When an arc flash analysis is conducted periodically, it evaluates these hazard prone areas and corrective actions are taken.
Ensuring Regulatory Compliance
Maintaining conformity with the electrical safety standards, for example OSHA and NFPA, is essential to any company. OSHA requires employers to adhere to workplace safety standards, and NFPA 70E provides detailed provisions on electrical safety. Performing an arc flash analysis helps facilities maintain compliance with these safety requirements, thus eliminating chances of the firm facing penalties in future.
Since arc flash studies identify and address potential hazards in workplaces, as well as define the appropriate personal protective equipment, an arc flash greatly decreases the likelihood of electrical related accidents and injuries.
