In the realm of electrical safety, understanding the concept of incident energy and its rating in calorie per centimeter squared (cal/cm²) is crucial, particularly when it comes to arc flash protection. This article will discuss the incident energy rating, its significance, and its role in determining the level of protection required to ensure the safety…
The Importance of Ground Fault Circuit Interrupters (GFCIs) in Electrical Safety Ground Fault Circuit Interrupters (GFCIs) are an essential component of electrical safety in modern homes and workplaces. These devices are designed to protect against electrical shock hazards by quickly disconnecting the power supply in the event of a ground fault. In this article, we…
OSHA requires unqualified people to receive training for the electrical hazards that they’re exposed to.

It controls a machine on the factory floor. It has four motor starters, individual circuit breakers for those motor circuits, ice cube…
I began my first job in electrical maintenance when I was hired in at Terre Haute Malleable and Manufacturing Company in 1984; a long-since-closed iron foundry in Terre Haute, Indiana. It was a one-hundred-year-old facility, dark, with dirt floors made of sand and coal dust and known by the workers as The Malleable. Some…
I want to thank the Central Indiana ASSE, the Indiana Chamber of Commerce and most of all the 50 people that attended my talk today, at the Indiana Safety and Health Conference, Electrical Safety For Managers, Updated For 2018 70E. It was a fun session and a great turnout. Watch for next years conference February 26-28,…
70E Topics Snapshot Introduction This is meant to serve as a snapshot of important 70E topics. Before work begins on equipment that would expose workers to electrical hazards, it must be de-energized, unless you can justify working live. OSHA and 70E are clear on this. The three ways to justify working live are if de-energizing…
When selecting arc flash PPE using the category method; the fault current and clearing time parameters are key to doing it correctly. It’s time we got serious about these parameters
Electrical safety in an R&D facility or laboratory can be challenging. The rules for R&D labs have been broadened in the 2018 edition of NFPA 70E.
