As the electrical industry addresses arc flash electrical safety concerns, it now acknowledges the high risks associated with what used to be normal maintenance tasks. In many cases, excessively high arc flash incident energy levels require all maintenance to be done with equipment de-energized, despite the fact that it may not always be considered feasible. In addition to the usual …
What is human error? A human error is the outcome of an action that does not produce results as intended. It can be summed up by saying things did not go as planned. The 6P Rule (Proper Prior Planning Prevents Poor Performance) can go a long way to preventing a human error, but there is still that human factor. James …
Protection from hazards always begins with proper prior planning. An important aid to correctly and thoroughly planning a job includes using a tool known throughout the industry as a pre-job briefing, commonly called a PJB. This tool is called a tailboard or tailboard meeting in construction parlance, but no matter what it is called, PJBs are all designed to do …
Chances are you are in an electrical career you love: Testing, maintaining, installing, commissioning, designing, rebuilding, engineering, improving…and generally making electrical power systems safer and better. But are you doing so with a focus on managing the possible onset of acute or chronic fatigue? We live in a busy world — do more with less; be efficient in your tasks; …
Everyone wears clothes, at least when out in public. However, not everyone needs to wear clothes specially designed and tested to protect them from hazards they could find in their workplace. If your employees work on or near electric power, generation, transmission, and distribution equipment, specialized clothing is necessary for certain tasks. OSHA 29 CFR 1910.269 states that employers must …
Sulfur hexafluoride, also known as SF6 gas, is a commonly used and excellent insulator found in many medium to large circuit breakers protecting transmission and distribution equipment. It has been argued that gas-filled breakers are superior to those filled with oil, air, or a vacuum. They operate cooler and with no noise or gas emissions and are considered relatively low …
