In a lot of older plants, personnel who are locking out equipment are not granted the convenience of a “local electrical disconnect,” meaning they have to use what I call “knife disconnects” such as this:
Or do we make the qualified electrical workers the “gatekeepers” of all electrical LOTO, and thus only they operate these switches?
When workers who are NOT “qualified electrical workers” operate these types of electrical disconnect(s), are we training them on the proper “one-arm technique” or, as I was trained to call it, the “left-hand rule”?
