Electrical safety is not just about checking boxes; it’s about protecting people, preventing downtime, and preserving assets. Whether you’re managing a building, a manufacturing, a processing plant, a hospital, or a data center, the risks of electrical failure are real. That’s why proactive strategies are essential, and two of the most powerful tools at your disposal are infrared thermography and an arc flash study.
But what happens when you combine them? You unlock a smarter, safer, and more cost-effective approach to electrical risk management.
Why Electrical Safety Requires a Multi-Layered Approach
Electrical systems are complex. One faulty breaker or corroded connection can spark catastrophic outcomes, ranging from equipment failure to arc flash explosions. That’s why relying on a single inspection method just isn’t enough.
Infrared thermography and arc flash studies serve different (but complementary) purposes:
- Infrared thermography finds invisible problems, like overheated breakers, loose wire connection, or unbalanced loads.
- An Arc Flash Study, usually conducted alongside a Short Circuit and Coordination Study, assesses the potential incident energy levels that may occur during an electrical fault. It assesses the intensity of thermal risks, establishes arc flash limits, and delivers essential details for Qualified Electrical Workers to choose the suitable level of personal protective equipment (PPE) as mandated by NFPA 70E and OSHA regulations..
When used together, these tools create a more complete picture of your facility’s electrical health and help prevent disaster before it starts.
What Is Infrared Thermography Inspection?
Infrared thermography Inspection is a non-invasive diagnostic tool that detects heat emitted from electrical components. Moreover, think of it like X-ray vision for hot spots. When an electrical wire connection is deteriorating or a circuit is overloaded, it produces excess heat, well before it fails. An Infrared Inspection is a survey of all the electrical equipment with potential problem areas identified.
IRT uses thermal cameras to visualize these heat anomalies in real time.
For Electrical equipment, common applications include inspections of:
- Panelboards
- Switchboards
- Switchgears
- Circuit breakers
- Transformers
What it detects:
- Loose or corroded connections
- Overloaded circuits
- Phase imbalance
- Overheated fuses or breakers
- Blocked ventilation issues
This kind of predictive maintenance allows facility teams to fix problems before they cause downtime, or worse.
What Is an Arc Flash Study?
An arc flash study is a detailed engineering analysis that models the energy release from an electrical arc fault. Additionally, this study is used to calculate how much heat (measured in incident energy) could be produced during a fault, and how far that energy might travel.
Why it matters:
Arc flash events can cause severe burns, blindness, or death in less than a second. The study helps determine:
- Required PPE levels
- Arc flash boundaries
- Incident energy levels
- Proper labeling for each piece of equipment
Conducted using NFPA 70E and IEEE 1584 standards, this study ensures that electrical workers are protected and aware of hazards.
Why Do They Work Better Together?
Combining infrared thermography and arc flash studies isn’t just smart, it’s genius. It is efficient, cost-effective, easy to coordinate, and less down time! Here’s why:
1. Efficiency in Data Collection
To perform both services, a Qualified Electrical Worker must carefully and safely open or remove panel covers, and both the Study Technician as well as the Arc Flash Technician will capture required data. Therefore, if you do each service separately, that means twice the labor for the QEW and twice the downtime if an outage is required
But if you do them together?
You reduce the disruption, save on labor, and streamline compliance.
2. Stronger Data, Better Outcomes
Performing infrared inspection and arc flash data collection together allows for stronger data and better outcomes. The Infrared Inspection catalogs all electrical equipment and rotating machines for a complete survey and often, panelboard covers must be removed. Collecting Arc Flash, Short Circuit, and Coordination study data at the same time allows for a complete, accurate, and real-world data collection process.
3. Insurance & Code Compliance
Most insurance carriers now require facilities to:
- A Arc flash study evaluation every 5 years or when there are changes in the electrical distribution system
- Conduct infrared inspections annually
Doing both on schedule and combining them when possible helps:
- Lower insurance premiums
- Avoid denied claims after an accident
- Reduce liability
- Comply with OSHA and NFPA 70E safety regulations
Real-World Case: Why Timing Matters
A manufacturing facility scheduled its annual infrared inspection and arc flash study six months apart. As a result:
- They paid twice for site access, permits, and labor.
- Equipment had to be de-energized twice, affecting production schedules.
- Missed thermal data during the arc flash study reduced label accuracy.
The following year, they combined both services and reduced total cost by over 30%, while improving their overall electrical safety strategy.
Key Benefits of the Combined Approach
| Benefit | Individual Services | Combined Approach |
| Predictive Maintenance | ✓ | ✓✓ |
| Accurate PPE Labeling | ✓ | ✓✓ |
| Labor Efficiency | ✗ | ✓✓ |
| Equipment Downtime Reduction | ✗ | ✓✓ |
| Compliance with NFPA 70E & OSHA | ✓ | ✓✓ |
| Insurance Premium Reduction | ✗ | ✓✓ |
Common Pitfalls to Avoid
Even with the best intentions, some facilities make critical errors:
- Skipping thermal scans during arc flash data collection process
- Failing to re-evaluate and update an arc flash study when load conditions changes or when electrical distribution system is reconfigured
- Relying on outdated arc flash warning labels after renovations or upgrades
- Not factoring in seasonal load fluctuations (e.g., HVAC or production lines)
Avoid these mistakes by aligning your infrared inspections and arc flash studies.
How Often Should You Schedule Each?
- Arc Flash Study – Every 5 years, or sooner if major system changes occur
- Infrared Thermography – At least once per year
Bonus Tip: Perform both in the same month every year—one trip, one technician team, one report.
Safety Through Synergy
Electrical safety isn’t a one-time project. It’s a continuous process built on good data, smart decisions, and proactive maintenance. Therefore, when you combine infrared thermography with an arc flash study, you not only save time and money, you raise the bar for workplace safety.
