What is Arc Flash?
Arc Flash Labeling
Labeling arc flash hazard areas is vital to the safety of your facility! Through proper labeling you can help prevent accidents related to arc flash, and mitigate other electrical risks. Arc flash incidents are more easily prevented when employees are aware of the risks and dangers they face.
DID YOU KNOW...The labeling requirement is the responsibility of the employer, not the manufacturer or installer of the equipment.
What needs to be labeled?
The NEC states that any of the following types of electrical equipment located in manufacturing and commercial establishments (other than dwelling occupancies) must be field marked with a warning label if subject to examination, adjustment, service or maintenance while energized:
- Switchboards
- Panelboards
- Industrial control panels
- Meter socket enclosures
- Motor control centers
A proper arc flash warning label should have a clearly visible color bar, preferably bright orange (or red for “Dangerous” categories), with the appropriate warning or hazard sign/symbol. The label should inform the viewer of the presence of an arc flash hazard, including information on hazard boundaries and Personal Protective Equipment (PPE). It is critical that the label be durable and long-lasting enough to hold up to harsh conditions.
When you have an Arc Flash Hazard Analysis performed on your facility we will provide you with the proper labels for each piece of equipment in your system. Our arc flash labels are compliant with all safety standards and both warn of an arc flash hazard and show the relevant incident energy & the corresponding hazard/risk category.
