What Is An Arc Flash Survey?

Electrical safety is a critical part of operating any commercial or industrial facility. Employees who work on or around energized electrical equipment face potential hazards that require careful planning and proper safety procedures. One of the most important tools for evaluating these risks is an arc flash survey. By identifying potential hazards and providing critical safety information, an arc flash survey helps facilities create a safer work environment while supporting compliance with applicable electrical safety standards.

At TCS Electrical, we perform comprehensive arc flash surveys to help commercial and industrial facilities better understand the risks associated with their electrical systems. Our goal is to provide the information needed to improve employee safety, support maintenance planning, and help facilities operate with greater confidence.

Understanding
Arc Flash Safety

TCS Electrical provides professional arc flash surveys to help facilities identify electrical hazards, improve workplace safety, and better understand their electrical systems. Our detailed evaluations provide the information needed to support safer work practices and reliable system management.

What is an arc flash?

An arc flash is a dangerous release of electrical energy that can occur when an electrical fault creates an arc between energized conductors or equipment. The event can generate extremely high temperatures, intense light, pressure waves, and molten metal in a fraction of a second.

While arc flashes are relatively uncommon, the potential consequences make proper planning and hazard assessments an essential part of facility safety.

What is an arc flash survey?

An arc flash survey is a detailed evaluation of your electrical system that identifies potential arc flash hazards and calculates the level of incident energy that may be present at various pieces of electrical equipment.

The survey also identifies the appropriate level of personal protective equipment (PPE) for employees who may work on or near energized equipment and provides information used to create arc flash warning labels.

Why is an arc flash survey important?

The primary purpose of an arc flash survey is protecting employees. By understanding where hazards exist and how severe they may be, facilities can establish safer work practices and ensure employees have the information necessary before performing electrical work.

In addition to improving workplace safety, arc flash surveys provide valuable information that supports maintenance planning and electrical system management.

What information does the survey provide?

An arc flash survey evaluates the electrical distribution system, analyzes available fault current, and calculates incident energy levels throughout the facility. The results are used to produce equipment labels and documentation that help employees understand potential hazards before beginning work.

The survey also provides facility managers with a better understanding of how their electrical system performs under fault conditions.
