Electric shock may result from badly maintained or unearthed (ungrounded) electrical equipment, especially portable tools. All dangerous parts of machinery, especially abrasive wheels, should have adequate guarding, with automatic lockout if the guard is removed during processing.
ATTENTION: Servicing energized industrial control equipment can be hazardous. Severe injury or death can result from electrical shock, burn, or unintended actuation of controlled equipment. Recommended practice is to disconnect and lockout control equipment from power sources, and discharge stored energy in capacitors, if present.

· The entire system is enclosed in a large oven, the tentering chamber. Each claw clips the film upstream, moves along the track, opens at the exit, and returns at the same speed to the initial position to clip the film. The bioriented film traverses a gauge measurement station (for automatic control of die aperture) and is winded.
· No matter in metal mines or coal mines, an emulsion pump station has a wide range of application market and can play an important role. In this paper, the frequency conversion constant pressure control system of the mine emulsion pump station is taken as the research object. The two kinds of water-based drawing fluids used are dispersed drawing fluid and emulsion drawing fluid.
Circuit breakers are the "final control elements" of the electric power industry, akin to control valves in the process industries. They are strictly on/off devices, used to make and break connections under load in power systems. Circuit breakers automatically open when dangerous circuit conditions are detected.
