The Importance of Arc Flash Studies for Industrial Electrical Safety
Electrical safety is critical for all industrial environments, particularly those with larger, more intricate electrical systems, as their reliance on these types of systems increases. In industrial environments, an arc flash is considered one of the most unpredictable and dangerous hazards, capable of causing severe injury, failure of expensive electrical equipment, and extended periods of operational shutdown. To mitigate arc flash hazards, most industries use Arc Flash Studies (AFS's) and other specialised assessments to identify hidden risks associated with their electrical networks. Trustworthy companies such as LS Electricals provide complete arc flash study for industrial electrical safety resources to help industry ascertain, manage, and reduce risks associated with arc flash hazards.
What is an Arc Flash and Why Is It Dangerous?
An arc flash occurs when an electric current moves away from its intended path through the air between two or more conductors. This forces the electric energy into a plasma arc capable of developing temperatures that can exceed 35,000 degrees F. Such extreme temperatures are capable of causing severe burns, melting metals and igniting surrounding materials at a rapid rate, making arc flashes among the most dangerous electrical incidents in industrial facilities.
In addition to high heat, an arc flash produces a large pressure wave and an intense shock wave, along with an extremely bright flash and loud noise, which has the potential to cause injuries to workers standing several feet away. Molten metal particles may be thrown from the arc at extremely high velocity, resulting in serious wounds and potential blindness. Equipment in close proximity to an arc flash may also sustain catastrophic damage, resulting in costly repairs and potential fires. Arc flashes develop suddenly and without warning, so it is important for industrial facilities to perform precise, data-driven arc flash studies to identify and eliminate any hazards associated with arc flash events. For this reason, arc flash study has become a global industry standard for industrial electrical safety.
Why are Arc Flash Studies Critical for Industrial Safety?
Arc flash studies are an integral part of an organisation's overall approach to industrial electrical safety. Arc flash study provides an organisation with a complete profile of the electrical system’s performance during an electrical fault condition. Arc flash study identifies the incident energy levels, arc flash boundaries, and risk zones of the entire electrical system. Without these studies, workers will be unaware of any hazards they may face during electrical operations, and they may be using insufficient PPE.
In today’s society, many organisations depend on arc flash studies to provide them with the information necessary to determine how safe each electrical panel, switchgear, or distribution board is for workers. Arc flash study assesses the degree of hazard (short-circuit levels), how well the electrical system is being protected (protection coordination), how fast the electrical breakers will trip when there is a fault (tripping times), and finally, the voltage of the electrical system. With a thorough evaluation by the LS Electricals, an organisation will have a clear understanding of where the most significant arc flash hazards are located in their electrical system.
Another significant reason for requiring an arc flash study for industrial electrical safety is compliance with electrical safety standards. Electrical safety standards, such as NFPA 70E and IEEE 1584, require that arc flash studies are performed periodically and updated to ensure that all facilities are compliant with the current standards and guidelines for safety. Failure to comply can result in penalties, complications with insurance, and possible loss of operations. By conducting updated assessments of arc flash hazards, industries will be able to achieve compliance with legal requirements and provide a safer workplace for their employees.
Arc flash studies also provide increased reliability of the electrical systems because the protection coordination and breaker settings are evaluated so that each fault can be cleared in the least amount of time possible during the study. Therefore, as part of the study process, LS Electricals revises breaker coordination and settings to minimise the severity of arc flash energy and subsequently increases the operational performance of their electrical systems.
The cost of conducting arc flash studies for electrical safety in an industrial environment is minimal when compared to the potential losses associated with even one accident caused by an arc flash. Potential losses associated with an arc flash accident include damaged equipment, medical expenses, lost production, and insurance claims. Therefore, conducting arc flash studies minimises the risk of incurring numerous losses through increased performance of electrical systems and protection to personnel.
