Arc flash labels

A label carrying incident energy, working distance, arc flash boundary and the PPE required for energised work.

1 products · substrates: polyester, vinyl

What it is

A warning label carrying the calculated incident energy, working distance, arc flash boundary and the resulting PPE category for one specific piece of equipment. Every number on it comes from a study of that installation.

When to choose it

These are not chosen so much as required by the study that produced them. What is chosen is the stock, and the decision is how long the label must stay accurate: the numbers are only valid until the upstream protection changes.

What decides the order

The values, not the label. A durable label carrying superseded incident energy is more dangerous than a blank one, because somebody will dress for it. Any change to the protective device settings invalidates every label downstream of it.

Choosing between arc flash labels

This is the one artifact here whose content you do not choose. The values on an arc flash label come from an incident energy analysis performed by a qualified engineer, and the label reproduces that study's output in the required format. What you are choosing is durability and placement. Laminated polyester is specified for print permanence rather than mechanical toughness, because the environment inside an electrical room is mild and the service life is measured in decades, so the failure mode is fade rather than damage. Placement is on the outer face at eye height, readable before the enclosure is opened.

What serialising arc flash labels adds

An arc flash label is authoritative in appearance and silent about its own age, which is a dangerous combination on a document somebody reads to decide what protective equipment to wear. A worker has no way to tell whether the study behind the label reflects the current configuration or one replaced when the service was upgraded. Binding the label to a record makes the study date and revision history reachable from the equipment itself, so the label carries both a conclusion and the means to check how old it is. On every other artifact here the record proves work was done. On this one it informs a decision about somebody's safety.

The record mechanics are the same for every artifact and are set out on how inspection records work.

What happens after you order

Because the content comes from a study, the proof stage is a check that the values transcribed match the study output, which is worth doing carefully since a transcription error here has consequences a typo elsewhere does not. Production begins once you approve the layout. Labels arrive bound to a record that carries the study date, so a scan tells a worker how current the analysis is. Reorders are triggered by a study revision or a system change rather than by a calendar, which is why this artifact does not follow an annual rhythm.

The full sequence, including what the proof shows and how approval works, is on how ordering works.

Questions about ordering arc flash labels

Do you calculate the incident energy?

No. That is engineering work performed by a qualified engineer, and the values on the label come from their study. We print to the required format with the values you supply and bind the label to a record carrying the study date. We do not calculate, verify or certify the numbers.

Where should the label go?

On the outer face at eye height, readable before the enclosure is opened. A label inside the door is read after the decision it was meant to inform, which defeats the purpose. This is the placement decision with the most direct safety consequence on the site.

When do we reorder?

When the study is revised or the system changes, not on a calendar. That is why these are ordered against a project rather than annually, and why it is worth ordering them at the same time as the associated panel identification rather than separately.
