Arc Flash Hazard Analysis

We build arc flash programs
that stay current.

The modeling is the part people picture: a short circuit study, protective device coordination, and incident energy calculated at every panel, run in whatever software your other engineering already sits in. That work has an end date. What comes after it doesn't, because the facility keeps changing and a label only protects somebody as long as it still matches the system behind the door. Most of the exposure we come across is a good study that quietly stopped describing the building.

Your safety manager can walk up to any panel in the facility and know the number on that label is the right one.
Choosing an approach

Who owns the program after the study is delivered.

The study is a document with a date on it. Somebody has to keep the labels, the procedures and the training current as the facility changes around it.

One-Time Compliance Vendor

A vendor does the study, delivers the report and labels, and the engagement ends. Lower upfront cost, but nobody owns the updates that come later.

Workable if your layout rarely changes and EHS already holds safety documentation tightly.
In-House EHS Management

Your EHS team owns the program after the study, tracking changes and scheduling retraining. Works when they have the time and technical depth.

Good if your EHS staff have both the time and the electrical depth to track it.
Ongoing Engineering Partner

An engineer stays attached to the system, reviewing changes as they happen and keeping the study, labels, and procedures current together.

Best when the system changes often, or when you'd rather not be the one deciding whether a change triggers a re-study.
How we help

Four parts of a complete arc flash program.

Whichever approach suits your facility, these four elements have to remain aligned as the facility changes.

01
The Study Itself A single line diagram, a short circuit study that accounts for utility contribution, system impedance and X/R ratios, a protective device coordination study, an evaluation of whether your protective devices are adequate for the fault current they would see, and the incident energy calculation on top of all of it. We model in SKM Power*Tools, ETAP, EasyPower or WindMil, depending on what your system and your other engineering already sit in.
02
Labels That Match the Study Nominal voltage, arc flash boundary, incident energy at the working distance, and the PPE that calls for, posted on the equipment and matching the study that is current rather than whichever revision happened to go up last.
03
Updated Work Procedures Energized work permits, approach boundaries, and the written procedures your people work to, revised whenever the study is. Procedures written against a superseded study are the quietest failure in the whole program.
04
People Trained to What Is Posted Qualified person training has its own clock under 70E, not more than three years between sessions, and it has to reflect the numbers on the equipment today rather than whatever the program looked like when someone was hired.
When this needs to happen again: 70E asks for two different things and they get conflated. The assessment has to be updated whenever a major modification or renovation happens, which is the one that actually catches most facilities. Separately, it has to be reviewed at intervals not exceeding five years, and a review is not automatically a new study. If nothing has moved, an engineer can look at it and confirm it still holds. In a facility that is running, though, something usually has moved.
Engineering Review

Send us your study, or just the year it was done.

We review what you send and follow up about what has likely changed since, and whether it is worth doing anything about yet.
