Electrical Risk Management: A Facility Manager’s Guide

Most facilities treat the electrical room the way they treat the roof: nobody looks at it until something leaks. The difference is that a roof failure is inconvenient and an electrical failure can be fatal. An arc flash releases temperatures several times hotter than the surface of the sun in a fraction of a second, and it happens most often during routine work — racking a breaker, opening a panel, taking a reading.

Regulators know this. OSHA cites employers under the general duty clause and NFPA 70E is the standard of care they measure against. Insurers know it too: carriers increasingly ask for an arc flash study, a coordination study and a thermography report before renewing a commercial policy. If those documents do not exist, the exposure sits with ownership.

The goal of this guide: give you a short list of deliverables that, once on file and kept current, move your building from “we hope it is fine” to demonstrably managed.

Everything else in electrical risk management hangs off these four items. If your facility file is missing any of them, start there.

Notice the first row. A surprising number of studies are built on a one-line diagram that no longer matches the building — tenants added loads, a contractor swapped a breaker, a transfer switch went in without anyone updating the drawing. A study on a wrong one-line is a wrong study.

An arc flash study calculates the incident energy at each panel, switchboard and piece of equipment, then translates that into an arc flash boundary and a PPE category. The output is a set of labels on the gear and a report that tells your electricians — in-house or contracted — exactly what they are walking into.

Three things separate a useful study from a shelf document:

• It is engineered, not templated. The calculations follow IEEE 1584 and the report is reviewed and stamped by the Texas-licensed PE firm we partner with. Generic labels printed from a spreadsheet do not hold up in an OSHA inquiry.
• It comes with a coordination study. Correctly set breakers often reduce incident energy dramatically; the study should recommend settings, not just measure the status quo.
• Somebody implements it. Labels applied, settings adjusted, one-line corrected. We do the field work ourselves rather than handing over a PDF.

What it protects: OSHA penalties start in the five figures per violation, and a single injury claim from an unlabeled panel routinely runs to seven. Against that, a study for a mid-size commercial building is a rounding error.

Loose lugs, overloaded phases and failing breakers all announce themselves the same way: heat. Infrared thermography sees it months before it becomes smoke. The scan is performed on live equipment under normal load — no shutdown — and takes a few hours for a typical building.

The report you should expect lists each anomaly with a thermal image, a visible-light reference photo, the measured temperature rise (Delta-T) against a reference component, and a severity class that tells you whether to fix it this week or at the next planned outage.

Who does it matters. Owning a thermal camera is not a qualification. Ask for Infraspection Institute Level II certification; it covers emissivity, load conditions and the analysis that turns a colorful picture into a decision.

Facilities that stay compliant do not rely on memory. Put the electrical file on the same calendar as the fire alarm test and the elevator inspection.

• Monthly: visual walk of electrical rooms — clearances kept, no storage against gear, no signs of water, panel covers on.
• Annually: infrared scan of switchgear, panelboards, MCCs and transformers; repair anything rated above “monitor.”
• Every 3 years: exercise and test protective devices; verify emergency and egress lighting.
• Every 5 years or after any change: update the one-line, re-run the coordination and arc flash study, re-label.

Tie each item to a named person and a document in the file. When a carrier or an inspector asks, the answer is a folder, not a phone call.

Do not try to do everything at once. The order below fixes the highest risk first and makes each following step cheaper.

1. Field verification of the one-line diagram. Everything depends on it.
2. Thermography scan. It finds the problems that could hurt someone this quarter.
3. Short-circuit, coordination and arc flash study, PE-stamped, with breaker settings adjusted.
4. NFPA 70E labels on every piece of gear, and a copy of the report where your electricians can find it.
5. Calendar the refreshes.

We handle all five for commercial and high-rise properties across The Woodlands, Spring and Greater Houston, and we stay involved after the study is delivered. A no-obligation risk assessment is the usual first conversation.
