KIRK® safety interlocks protect the safety of your employees and equipment by ensuring a predetermined sequence of operations is followed every time, without fail. When performing maintenance on or emptying hoppers, electrodes in excess of 10,000 volts present a serious risk to life. To ensure the safety of employees performing maintenance, it is imperative that the hazardous energy is isolated and cannot be inadvertently re-energized during maintenance procedures. KIRK® trapped key interlocks ensure that the power is isolated and grounded before hopper doors can be accessed. A typical ESP application includes trapped key interlocks on switchgear, transfer switches, access doors, and valves.
Trapped key interlocks allow safe maintenance procedures
A trapped key interlock system ensures the safety of operators when performing maintenance on a hopper. Before access is granted to any hopper doors, hazardous energy is disconnected and grounded. The trapped key interlock system ensures a predetermined sequence of events is followed.Watch the Video
