An arc flash risk assessment is the NFPA 70E-2027 process that identifies arc flash hazards, estimates how likely and how severe an injury would be, and decides which protective measures, including PPE, each task needs. AFSC builds it on calculated incident energy, so every decision your crews follow rests on engineering numbers.
Why now
Signs your risk assessment is overdue
Crews pick PPE by habit
If nobody can point to the number behind a PPE choice, the choice is a guess. The assessment replaces habit with a documented decision.
Labels and procedures disagree
A label says one category and the work permit says another. Inspectors notice that mismatch fast.
The system changed
New gear, new settings or a new utility feed change the hazard. The assessment has to follow the hardware, not the calendar alone.
What the assessment delivers
| Deliverable | What you get |
|---|---|
| Task inventory | Every energized task your crews perform, listed by equipment |
| Hazard identification | Where an arc flash hazard exists and where it does not |
| Likelihood and severity | Each task rated for likelihood of an arc flash and the incident energy in cal/cm² at the working distance |
| Risk controls | Controls ranked from elimination down to PPE, with what to change first |
| Boundaries and PPE | Arc flash boundary and PPE for each task and piece of equipment |
| Documentation | A PE-reviewed record you can show an inspector or insurer |
How the assessment runs
Walk the tasks
We review your energized work: switching, racking, testing, troubleshooting, and who does each one.
Calculate the energy
Incident energy comes from a model built to IEEE 1584-2018, not from a generic table.
Rate and control
Each task gets a likelihood rating and the control that cuts risk the most.
Deliver and brief
PE review, the written assessment, and a briefing for supervisors who sign work permits.

Arc flash assessment vs a label refresh
An arc flash assessment decides how work gets done safely; a label refresh only reprints numbers. The assessment looks at each task, the equipment condition, and the controls available before it settles on PPE. Reprinting labels without that review leaves the same unsafe habits in place under newer stickers.
Arc flash risk assessment NFPA 70E checklist
An arc flash risk assessment NFPA 70E accepts must answer three questions for every task: is there an arc flash hazard, how likely and how severe is harm, and what controls bring the risk down. It must be documented, it must follow the hierarchy of controls, and it must be reviewed when systems change.
Frequently asked questions
Question not here? Ask an engineer
What does NFPA 70E require to assess arc flash risk?
NFPA 70E requires you to identify arc flash hazards, estimate the likelihood and severity of injury, and decide whether additional protective measures, including PPE, are needed. You must document the result, apply the hierarchy of risk controls, and keep the assessment current as equipment, settings or work practices change.
What three factors are determined in an arc flash risk assessment?
The three factors are whether an arc flash hazard exists, the likelihood and severity of harm if an arc flash occurs, and the protective measures needed, including PPE. Together they tell a supervisor whether a task can go ahead energized and exactly what the worker must wear.
Do we need a full engineering study first?
Yes, in most cases. You need incident energy values, and those come from an engineering model. If you already have a current model, we build the assessment on it. If not, we include the calculation in the same scope, so you buy one coordinated piece of work rather than two separate projects.
How is this different from the PPE category tables?
The PPE category tables in NFPA 70E-2027 only apply inside strict limits on fault current and clearing time. Outside those limits, they give the wrong answer. A calculated assessment uses your actual numbers, which often lowers PPE on low-energy gear and flags the few locations that need serious controls.
Who signs off the assessment?
A US-licensed Professional Engineer reviews the assessment before you receive it. Your own electrical safety program owner then adopts it into procedures. We brief the supervisors who issue energized work permits, so the people making daily decisions understand the reasoning behind each control and PPE choice.
Will the assessment slow down maintenance work?
No. It usually speeds work up. Crews stop debating PPE at the panel because the answer is on the label and in the permit. Where incident energy is high, we propose controls such as remote racking or maintenance switches, so the riskiest tasks become routine instead of special events.
