Understanding the Critical Role of Arc Flash Studies

Updated: Nov 20, 2024

Arc flash studies are essential for ensuring electrical safety in workplaces, helping to protect both workers and equipment from the devastating effects of arc flashes. These explosive electrical incidents occur when an electrical fault causes a sudden release of energy, leading to extreme heat, blinding light, and forceful blasts. The risks posed by arc flashes are significant, as they can result in severe injuries, fatalities, and extensive damage to electrical systems and infrastructure.

 

To mitigate these risks, SMS Engineering provides comprehensive Arc Flash Studies - a thorough safety assessment aimed at identifying and managing potential hazards in electrical systems.



The Importance of Arc Flash Studies

Arc Flash Studies are crucial for several reasons. First and foremost, they play a key role in protecting workers by identifying areas where the risk of arc flash incidents is high and ensuring proper protective measures are implemented.


These studies also help clients comply with safety regulations and industry standards, avoiding costly fines and ensuring a safe work environment.

 

Additionally, managing arc flash risks helps prevent damage to electrical equipment.


Without proper safeguards, an arc flash event can lead to injury or death, expensive repairs or replacements, interrupting operations and shortening the lifespan of your electrical systems. By proactively addressing these risks, our studies offer clients Peace of Mind, knowing their electrical systems are safe and compliant.


The Essential Components of an Arc Flash Study

Accurate field data collection is the foundation of an effective Arc Flash Study. At SMS Engineering, we gather this critical data in-house, working with certified electricians to ensure the information is precise. The accuracy of the entire study relies on the quality of the field data, which is why we prioritize thoroughness from the start.


Typically, the study begins with a short circuit analysis and protective device coordination. The short circuit study ensures that protective devices, like circuit breakers, can safely interrupt faults without them being damaged, helping to reduce equipment damage during an arc flash event.


Next, the protective device coordination study ensures that devices are selectively coordinated. This means that in the event of a fault, only the protective device closest to the issue will activate, isolating the problem while allowing the rest of the system to continue operating normally.


An Arc Flash Study starts with a comprehensive evaluation of the electrical distribution system. We analyze key data such as utility fault levels, equipment specifications, and cabling to assess potential risks. This information allows us to establish safe working distances, determine fault-clearing times, and set physical boundaries to reduce arc flash exposure. These parameters help ensure that workers understand the risks and take appropriate precautions.


Based on the calculated arc flash incident energy, we recommend the appropriate personal protective equipment (PPE) to minimize the risk of injury.


We also provide detailed arc flash labels for all electrical equipment, clearly identifying the level of incident energy and electric shock hazards, further enhancing safety and regulatory compliance.


Implementing Safety Measures

Upon completing the Arc Flash Study, we translate our findings into actionable safety measures. Detailed Arc Flash labels are affixed to electrical equipment, communicating critical information about the level of risk and required protective measures. These labels are essential for preventing accidents by making potential hazards clear to those working around live electrical systems.

 

In addition to labeling, SMS Engineering provides tailored safety training programs for employees. These sessions educate workers about the dangers of arc flashes, the importance of proper safety standards, and the correct use of personal protective equipment (PPE). This training fosters a culture of safety and preparedness in the workplace.



Moreover, we provide recommendations to mitigate risks, including equipment upgrades, breaker setting adjustments, and the installation of arc ducts to direct arc flash byproducts outside of the room. These recommendations aim to further reduce the chances of arc flash incidents and enhance overall workplace safety.
