Where It's Used.

Arc flash signage is required across every environment where electrical hazards are present.

Get in touch

Substations & Switchrooms
Indoor and outdoor electrical environments where arc flash risk is highest. Switchrooms need boundary signage at entry points and equipment-specific labels on every panel. Our signage handles the confined, high-temperature conditions found in indoor switchrooms.

Solar & Inverter Installations
Inverters and connection points present arc flash hazards on both sides of the system. Compliant signage on inverter housings and combiner boxes is a requirement. Our labels last the full life of the installation.

Battery Energy Storage Systems
Battery storage installations need arc flash signage wherever the assessed hazard level requires it. We supply custom safety signage for battery enclosures, racks, and associated switchgear.

FAQs.

When is arc flash signage required?

Arc flash signage is required on electrical equipment wherever the assessed hazard level triggers a signage obligation. Battery storage installations have separate requirements. Your arc flash study will confirm which assets need signage.

What information goes on an arc flash label?

A proper label shows the hazard level, safe approach distances, required protective equipment, equipment identification, and study date. Some sites also require the name of the study provider. We produce labels directly from your study data.

How often should arc flash labels be reviewed?

Every five years, or sooner if any change to the system affects fault levels — such as equipment upgrades, replacements, or changes to protection settings.

What is the difference between arc flash signage and arc flash labels?

Signage refers to general area warnings posted at room entries and along approach boundaries. Labels are equipment-specific, fixed directly to switchboards or panels, showing the calculated values from an arc flash study for that piece of equipment.

Do battery storage and solar installations need arc flash signage?

Yes. Battery storage installations need arc flash signage wherever the assessed hazard level requires it. Solar installations need signage wherever electrical hazards are present. Your study data will confirm the full scope.
