Arc Flash Risk Is Showing Up in More Places
Arc flash hazards are not new, but the environments where they occur continue to expand. Aging infrastructure, increased electrical maintenance, and growing energy systems mean more workers are operating near energized equipment.
In 2026, arc flash awareness is not limited to electricians alone. As work environments change, industrial maintenance, utilities, and energy workers are increasingly exposed, making education and proper PPE selection more important than ever. This wider exposure sets the stage for a closer look at what happens during an arc flash.
What Happens During an Arc Flash
An arc flash occurs when electrical current travels through the air between conductors, releasing extreme heat, pressure, and light. Temperatures can reach tens of thousands of degrees in a fraction of a second.
Without proper protection, the risk of severe injury is immediate. That is why understanding arc flash hazards is critical for anyone working near energized systems.
How Arc Flash Risk Is Measured
Arc flash protection is based on cal/cm², a measurement of thermal energy exposure.
Risk levels vary depending on:
- Equipment voltage and configuration
- Task being performed
- Distance from energized components
A formal arc flash study determines required PPE levels. Even without one, workers should understand when arc-rated protection may be necessary. Clarifying the distinction between FR and arc-rated clothing can help in making the right choice.
FR vs Arc-Rated Clothing: Knowing the Difference
Flame-resistant clothing protects against ignition and flash fire. Arc-rated clothing goes a step further and is tested to withstand specific levels of arc flash energy.
Not all FR clothing is arc-rated. For electrical work, choose the correct level of protection based on the task and potential exposure.
When uncertain about exposure, arc-rated FR gear offers added safety. Looking ahead, choosing the right arc-rated clothing in 2026 involves considering both protection and wearability.
Choosing Arc-Rated FR Clothing in 2026
Today’s arc-rated workwear is designed to balance protection and wearability. Modern AR garments offer:
- Improved comfort and mobility
- Layering options based on hazard level
- Durable construction for daily industrial use
Protection should never prevent a worker from doing the job safely and effectively. As you explore equipment options, here’s how to find suitable arc-rated FR clothing for your industry.
Arc Flash PPE FAQs
Do all electrical workers need arc-rated clothing?
No. Arc-rated PPE is needed only when an arc flash hazard exists, as identified by a hazard analysis or study.
No. Arc-rated PPE is needed only when an arc flash hazard exists, as identified by a hazard analysis or study.
Is FR clothing the same as arc-rated clothing?
No. Arc-rated clothing is always flame-resistant, but not all FR clothing is arc-rated. Arc-rated garments are tested to withstand arc flash energy.
No. Arc-rated clothing is always flame-resistant, but not all FR clothing is arc-rated. Arc-rated garments are tested to withstand arc flash energy.
Can arc-rated clothing be comfortable?
