Accidents that involve electricity can be caused by unsafe equipment, installation, environment, or work practices. Stay as far away as you can from electrical equipment and systems with exposed live components.
Anyone who makes their living by working with electricity quickly develops a healthy respect for anything with even a remote chance of being "live." Yet the pressures of the getting a job done on time or getting a mission-critical piece of equipment back on line can result in carelessness and uncharacteristic mistakes by even the most seasoned electrician.
Inductive heating, which typically occurs when phase conductors are routed around metal mounting channels, supports, or braces, can cause catastrophic and deadly failures in electrical distribution and control equipment.
Curb explosive potential with intrinsically safe tools. For those who work in industries where flammable materials are present—such as petrochemical and pharmaceutical plants, oil platforms, refineries, pipelines, and mining—the potential for an explosion is a daily reality. All it takes is a flammable material coming into contact with air and an ignition source.
Late on a Sunday afternoon the Kern County Fire Department responded to a call at a store on Rosedale Highway in Bakersfield, California. Crews found that a row of solar panels on the roof had caught fire. Some of the panels were still live when the crew arrived, so the fire crew had to take extra precautions until electrical power could be disconnected.
Out on the job site, concrete finishers stand ready to shape wet ready-mix into a new stretch of highway. Mixer trucks are lined up at the concrete batch plant,waiting to take on their loads. But hold on—an electrical problem has shut down the plant. It's time to call Keithly Electric.
Mixing higher voltage 480-volt three-phase cables in the same cabinet as lower voltage 24- or 120-volt control wiring and communication cabling can result in erratic operation or even complete failure of electronic equipment inside the cabinet. Knowing what is inside the cabinet before you open it, the specific wiring issues to look for once inside, what values to measure, and simple ways to correct problems can help alleviate many erratic and sometimes "mysterious" control and communication issues on the plant floor.
