What Is an Arc Flash Study and Why Does Your Facility Need One?

Electrical systems power everything in your facility — but they can also present hidden dangers. One of the most serious risks is an arc flash, a sudden and explosive release of electrical energy that can cause burns, injuries, and even fatalities. To keep workers safe and stay compliant with regulations, facilities are required to perform an arc flash study.

What Is an Arc Flash Study?

An arc flash study is an engineering analysis of your electrical system that:

• Identifies potential arc flash hazards.

• Calculates the amount of energy that could be released in an event.

• Determines the level of personal protective equipment (PPE) workers need.

• Provides clear labels and documentation for equipment.

  
  

Why It Matters:

1. Worker Safety: Arc flashes can reach temperatures of 35,000°F — hotter than the surface of the sun. A study helps reduce these risks.

2. Regulatory Compliance: OSHA requires employers to protect workers from electrical hazards. NFPA 70E provides the standard framework.

3. Cost Avoidance: Fines, lawsuits, and downtime from an incident can be devastating. A study is far less expensive than the consequences of not having one.

4. Clarity for Workers: Proper labeling and PPE requirements take the guesswork out of electrical safety.

   
   

When Do You Need One?

• New facility construction.

• Major electrical system upgrades.

• Every 5 years (per NFPA 70E), or sooner if system changes occur.
