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…
Transcription: Hi. I want to talk today about electrical enclosures and the space in front of those. It’s important that we keep those clear with depth of at least 36 inches and the width of the panel that could be opened up. The reason this is, and this is a contentious thing in every plant…
OSHA requires unqualified people to receive training for the electrical hazards that they’re exposed to. Now, when it comes to qualified people, you have to be qualified to do the electrical task that you’re performing. Under the word qualified comes a lot of things: We’re talking about training, we’re talking about being able to demonstrate…
Make sure these get done! De-energize. Unless the employer can justify live work, it is not permitted. Live testing and troubleshooting are allowed, but altering the circuit live is difficult to justify. Workers must be qualified for each electrical task they perform, and the electrical hazard they are exposed to. Workers must know how to…
Limitations Of Live Electrical Work First, let’s begin with the limitations of live electrical work. Hopefully, the only live work your people are performing is verification of zero volts during lockout/tagout and maybe some troubleshooting and other diagnostic work. Repair of electrical circuits, that is replacing of components or altering the circuit in any way,…
OSHA Training Requirements For Electrical Safety Based on the number of questions I get from clients, the electrical safety-related OSHA training requirements can be confusing. In simple terms, a company has to provide electrical safety-related work practices and train employees on them. A worker has to be qualified, trained and can demonstrate skills, on any…
The Main Circuit Breaker For This Control Panel Doesn’t De-energize The Panel Introduction This control panel is like thousands of control panels out in facilities today, and maybe even many in your facility. It controls a machine on the factory floor. It has four motor starters, individual circuit breakers for those motor circuits, ice cube…
Avoiding tight fitting clothing is essential if that clothing is being worn to protect you against the thermal effects of an arc flash. NFPA 70E states that the worker must avoid tight-fitting arc flash gear and that loose fitting clothes provide more thermal protection because of the “air spaces.”
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…
