NFPA70

If you work around electrical equipment, you’ve probably noticed that arc flash labels don’t all look the same. Some have orange headers with the word “WARNING” in black. Others have red headers with the word “DANGER” in white. So which one is correct? Are there codes or standards that require one over the other? The short answer is yes – but which label to use is not always obvious. In the article below, we will explore some of the reasons for this uncertainty. Where Arc Fla

Infrared cameras have never been easier to buy or use. They’re compact, affordable, and produce crisp images that might make thermography seem like a simple “point-and-check” exercise. That false sense of simplicity is exactly what gets people into trouble when attempting electrical reliability and safety inspections. User beware: bold colors don't tell the full story Every week at Monroe Infrared (a Guidant Power company), we meet technicians who bought a camera, tried to se

Infrared thermography is one of the most valuable technologies available to modern electrical maintenance, reliability, and safety teams. It enables you to identify failing components, hidden anomalies, and high-risk conditions without shutting down equipment or opening energized gear. It’s fast. It’s safe. And when used correctly, it can detect developing failures long before they become emergencies. Yet for all its value, infrared thermography is also one of the most misund

Every few years, facilities ask us the same question: “Why isn’t the update a fraction of the original price? Can’t you just rerun the old data?” It’s a fair question. And the answer is important for leaders, EHS managers, facility teams, and anyone responsible for electrical safety. Arc flash studies aren’t “one-and-done.” NFPA 70E and NFPA 70B both require a review at least every five years — and the reasons are practical, not bureaucratic. Electrical systems drift, utiliti
