Switchgear Application with Trapped Key Interlock Safety System
Protecting Personnel during Switchgear Maintenance
Within a substation, KIRK® trapped key interlocks are used to ensure the isolation of hazardous energy for several switchgear maintenance applications. Preventing the paralleling of two energy sources, ensuring a breaker is locked open (or closed) for maintenance operations, preventing the disconnection of breakers under load, and minimizing the potential of a hazardous arc flash are just a few applications where trapped key interlocks can be found.
Salvo loading dock safety systems prevent drive-aways during loading/unloading by interlocking the trailer’s air brakes with the dock door. This ensures that the trailer cannot depart until loading/unloading is completed and the dock door is locked closed. Salvo keeps your personnel and equipment safe by – eliminating human error.
