The Real Risk Behind Missing Arc Flash Labels

In any facility with energized electrical equipment, arc flash labels are more than just stickers—they are life-saving tools. Yet, it’s not uncommon to find missing, damaged, or outdated arc flash labels in commercial and industrial settings. This oversight doesn’t just jeopardize compliance; it puts workers directly in harm’s way. At Herzig Engineering, we help companies avoid these hidden dangers through comprehensive arc flash studies and on-site label application services. 

Why Arc Flash Labels Matter 

Arc flash labels provide critical information that helps workers: 

• Identify the presence of arc flash hazards 

• Determine the correct level of Personal Protective Equipment (PPE) 

• Understand the approach boundaries and incident energy levels 

  
  

According to NFPA 70E, every piece of electrical equipment likely to require examination, adjustment, servicing, or maintenance while energized must be labeled with the nominal voltage, arc flash boundary and a method for determining the required PPE. OSHA enforces these labeling requirements under the General Duty Clause and electrical safety standards. 

The Consequences of Missing Labels 

Missing or incorrect arc flash labels can result in: 

• Serious injuries or fatalities due to incorrect PPE usage 

• OSHA citations and fines 

• Increased liability for employers 

• Delays in maintenance and troubleshooting due to safety uncertainty 

  
  

In real-world scenarios, even experienced workers can make dangerous assumptions when labels are not present. The lack of clear hazard information creates unnecessary risks that could otherwise be mitigated. 

How Herzig Engineering Solves the Problem 

Our Arc Flash Studies include on-site label application by trained professionals. We ensure: 

• Every piece of required equipment is accurately labeled 

• Labels are durable, clear, and compliant with NFPA 70E 

• Updates are documented and maintained through our Client Portal for future reference 

We also perform Electrical Safety Audits to identify missing or outdated labels and implement a plan for correction.
