Did you know arc flash incidents cause an estimated 400 deaths every year? This figure is quite concerning, especially considering that almost all of these accidents can be avoided by performing a thorough arc flash assessment. Arc flash incidents can occur due to equipment failures, and unfortunately, these events often happen when workers are actively working with energized electrical equipment. Only qualified electrical engineers familiar with power studies and unique characteristics of PV power systems should perform an arc flash risk assessment for solar applications.

An arc flash is one of the most dangerous and explosive hazards in the electrical world. In a split second, it can cause severe injury, equipment damage, or worse yet, or worse. Yet many in the solar industry overlook the critical importance of arc flash studies. At Pure Power Engineering we take worker safety seriously. That's why we perform detailed arc flash studies as part of our power systems analysis. It's more than just a check box. These studies are essential for preventing accidents and keeping workers safe. Arc Flash Hazard Analysis is prescribed by the NFPA. These studies calculate the arc incident energy and determine how close workers can safely operate equipment. The data from these analyses inform warning labels guiding workers on the personal protective equipment or PPE they need. Those labels? They're not just stickers. They're lifesaving information that ensures workers know exactly what PPE to wear. Engaging in arc flash studies early in the project design stage allows us to value engineer systems for both safety and efficiency. By selecting the right equipment like fast-acting circuit breakers we can reduce arc flash hazards before they even become a risk. Waiting too long to conduct these studies can result in dangerous and expensive consequences. If arc flash studies are done after equipment is already procured the opportunity to reduce hazards is lost leading to long-term safety risks and costly operations. Arc flash risk comes down to two main factors.Fault current and fault clearing time. While we can't control the utility's fault current, we can reduce clearing times. But it's a delicate balance reducing arc flash hazards while ensuring the right overcurrent devices trip first. Arc flash studies don't just produce one label. They produce multiple. Arc flash hazards are real threat but they're also preventable. At Pure Power Engineering we take proactive steps to design safer, more efficient systems that protect your workers and your investment. Ready to prioritize safety in your next solar project?
