Arc flash events are among the most destructive and underestimated threats in electrical systems. A single arc blast can release more heat energy than the surface of the sun, sending molten copper and metal fragments across a room. These explosions—often caused by short circuits, human error, or aging electrical equipment—can result in severe burns, electrical shock, hearing loss, or death.
Bowtie Engineering’s arc flash studies are designed to prevent these catastrophic outcomes. Our process equips teams with the data, labeling, and protocols needed to protect workers, reduce incident energy, and comply with NFPA 70E and OSHA regulations. We help organizations understand their risks, label affected equipment, and take action before an arc flash occurs.
An arc flash occurs when electrical energy exits its intended path and travels through the air between conductors or from a conductor to the ground. This unplanned arc fault can trigger an explosive force known as an electrical arc flash.
Causes of arc flash incidents include:
Without proper controls and personal protective equipment, workers exposed to these electrical hazards face serious injury. That’s why arc flash safety must be integrated into every facility’s broader safety program and compliance efforts.
Bowtie Engineering’s arc flash assessment process follows NFPA 70E, OSHA 1910, and IEEE 1584 guidelines. Every project is handled by experienced electrical engineers and safety professionals who understand the dangers of arc flash at a practical level.
Each study includes:
We also document where energized electrical equipment presents a high risk, helping you identify special equipment that may require advanced controls or additional protective equipment.
Every arc flash incident is different but many are preventable. Bowtie’s arc flash studies are designed to deliver more than compliance paperwork. We help your teams:
With our help, you can map every panel, identify at-risk systems, and train your team to respond confidently even in high-pressure environments.
Bowtie also offers optional arc flash training that goes hand-in-hand with your arc flash study. These instructor-led or proctor-based sessions teach:
All training is aligned with national fire protection association standards and includes documentation of successful completion.
An arc flash study identifies risks in your electrical system and calculates incident energy levels at specific points. This helps determine arc flash boundaries, label panels, and recommend protective equipment.
They uncover hidden electrical hazards and help prevent electrical injuries through proper labeling, documentation, and PPE recommendations.
The study includes field evaluations, fault current calculations, arc flash labels, PPE recommendations, and compliance documentation.
Every 5 years or after major electrical changes, per NFPA 70E. If your system has changed recently, it’s time to reassess.
Yes. We provide recommendations for arc flash mitigation, including remote operation tools, system upgrades, or adjusting working distance.
Arc flash studies are not just required, they’re responsible. When you understand the causes of arc flash, prepare your team with proper training, and install accurate arc flash labels, you’re investing in more than equipment; you’re protecting lives.
Bowtie Engineering delivers field-proven strategies to help reduce arc flash injuries, prevent blast injuries, and ensure safety regulations are followed across your operation. From your first risk assessment to final PPE recommendations, we walk with you through every step.
Protect your workforce, improve electrical safety, and stay audit-ready.
