Top 5 Arc Flash Labeling Mistakes to Avoid

Arc flash studies are only useful if their results are communicated clearly — and that’s where equipment labeling comes in. Unfortunately, many facilities make labeling mistakes that put workers at risk and create compliance gaps. Here are the top 5 mistakes to avoid.

1. Missing Labels Altogether

It’s shocking how often equipment goes unlabeled. Every piece of electrical equipment likely to require servicing while energized must have a label.

2. Outdated Labels

Labels from an old study may not match current system conditions. This gives workers false confidence and creates serious risk.

3. Generic “Warning” Labels

OSHA requires more than just a warning sign. Labels must include incident energy levels, arc flash boundaries, and required PPE.

4. Labels That Are Hard to Read

If a worker can’t read the label quickly, it defeats the purpose. Small fonts, poor color contrast, or fading stickers are common problems.

5. Inconsistent Labeling Across the Facility

Mixing different formats or data points confuses workers. Standardization ensures clarity and compliance.

Best Practice:

Use durable, standardized, and compliant labels placed consistently on all equipment. Pair them with worker training to ensure the message gets through.
