Arc-rated clothing is essential for protecting workers from electrical hazards. However, many users overlook one critical detail—the arc flash label.
Understanding how to read this label helps ensure that the garment provides the right level of protection for the job. It also supports compliance with workplace safety requirements.
An arc flash label is a tag or marking on flame-resistant clothing that provides key safety information about the garment’s protective performance.
It typically includes:
Arc rating (ATPV or EBT)
Applicable safety standards
Fabric composition
Care instructions
This label helps users quickly identify whether the clothing is suitable for a specific hazard level.
Understanding each element of the label is important for safe use.
The arc rating indicates how much thermal energy the garment can withstand before causing injury.
Measured in cal/cm²
Higher value = higher protection
Used to match PPE to hazard level
This is the most critical value on the label.
Labels usually reference the standards the garment complies with, such as:
ASTM F1506
IEC 61482-2
NFPA 2112 (if multi-hazard)
These confirm that the garment has been tested for specific risks.
Some garments also display a PPE category level (CAT 1, CAT 2, etc.), which provides a quick reference for required protection.
However, the arc rating value is more precise than category alone.
The label may include:
Fiber composition
Fabric weight
FR or inherent FR identification
This helps users understand durability and performance characteristics.
Proper maintenance is essential to keep protective performance intact.
Typical instructions include:
Washing temperature limits
Restrictions on bleach or softeners
Drying recommendations
Following these guidelines helps extend garment lifespan.
Even experienced users can misunderstand arc flash labels.
Common mistakes include:
Relying only on PPE category instead of arc rating
Ignoring garment damage or wear
Using clothing without verifying standards
Misinterpreting ATPV values
Understanding the label correctly reduces safety risks.
Arc flash labels are more than just product information—they are a critical safety tool.
They help:
Ensure proper PPE selection
Support compliance with safety standards
Reduce risk of injury
Improve workplace safety awareness
In high-risk environments, correct interpretation of labels can make a significant difference.
To ensure labels remain useful:
Do not remove or damage labels
Replace garments if labels become unreadable
Inspect garments regularly
Maintain proper washing practices
Clear labeling ensures consistent safety performance.
Reading arc flash labels correctly is a key step in protecting workers from electrical hazards. By understanding arc ratings, standards, and garment details, companies can ensure that protective clothing matches the actual risk level.
Well-informed PPE selection leads to safer and more efficient operations.
