Arc Flash Hazard Analysis & Labeling

An arc flash is a violent, explosive release of electrical energy that occurs when an electric current leaves its intended path and travels through the air between conductors or to the ground. This phenomenon creates a "flashover" of light and heat, with temperatures reaching up to 35,000°F, more than three times hotter than the surface of the sun. An arc flash can be triggered in a fraction of a second from a fault such as a dropped tool or equipment failure. Proper safety mechanisms, such as PPE, training, and compliance with NFPA 70E can help reduce risk.

What to Expect

WHY IS AN ARC FLASH ANALYSIS NEEDED:

To protect your team and your power systems with a comprehensive arc flash hazard analysis. Additionally, per OSHA and NFPA 70E, Arc Flash analysis is required every 5 years, or with electrical changes. Something like adding back-up generation or replacing a breaker on a panel will require an updated arc flash analysis. Beyond the multi-million dollar toll of lawsuits and violations lies an even greater cost: the potential loss of life.

Arc flash studies are critical.

Determine PPE Requirements: The study calculates "incident energy" (heat levels) at each panel, which dictates the specific level of Personal Protective Equipment (PPE) workers must wear to survive an incident.

Mandatory Equipment Labeling: Results are used to create required labels that warn workers of the hazard level and the "Arc Flash Boundary", the distance at which they are safe from second-degree burns.

Regulatory Compliance: OSHA and NFPA 70E require employers to identify electrical hazards. Failing to have a current study (updated at least every 5 years) can lead to significant fines and legal liability.

Improved System Reliability: These studies often reveal "coordination gaps" where protective devices are incorrectly set, allowing you to fix issues that could lead to equipment damage or unplanned downtime.

Safety Boundaries: It defines the Limited and Restricted Approach Boundaries, ensuring only qualified personnel enter high-risk areas.

HOW IS AN ARC FLASH ANALYSIS CONDUCTED:

We identify hidden electrical risks, calculate incident energy levels, and provide compliant labeling that meets all OSHA and NFPA 70E standards. Our process begins with a comprehensive site walk-through and a review of your one-line diagrams. If your diagrams are outdated or missing, we can provide professional drafting services to create them for you.

Your project concludes with a detailed engineering report and customized arc flash labels, providing the documentation and visual warnings needed for full regulatory compliance.

Our studies go beyond simple compliance; they deliver the actionable insights necessary to protect your workforce, mitigate risk, and prevent costly operational downtime.

WHO CAN COMPLETE AN ARC FLASH ANALYSIS:

In Texas, an arc flash study is legally considered the "practice of professional engineering" and must be performed or supervised by a Licensed Professional Engineer (P.E.) registered with the Texas Board of Professional Engineers and Land Surveyors (TBPELS)

TIMELINE TO COMPLETE AN ARC FLASH ANALYSIS:

At Arc Defense Engineering Solutions, we prioritize efficiency alongside uncompromising quality. Although turnaround times vary based on the specific scope of the facility, our streamlined process allows us to finalize most moderately sized projects in just two to three weeks.

ARC FLASH ANALYSIS PRICING:

Our pricing is tailored to the complexity, scale, and available documentation of your electrical system. Project investments typically range from $7,000 for smaller facilities to $100,000+ for large, multi-site industrial campuses.
