Salvo loading dock safety systems

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 closed. Salvo keeps your personnel and equipment safe by – eliminating human error.

Perimeter guarding

KIRK®’s access interlock product offering provides solutions for all guarding applications, ensuring access permissions only once hazardous energy has been isolated. Incorporating access interlocks with time delay units or electro-motive force units adds additional safeguards to ensure residual energy has been fully dissipated and isolated prior to access.

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.

Uninterruptible power supply

Power outages in environments where power is critical can have drastic implications and risks. Data centers, medical facilities, telecommunications centers, and more rely on an uninterruptable power supply, or UPS, during unstable weather or power conditions. A KIRK® trapped key interlock system ensures that regular maintenance can be performed safely, and the UPS system can be placed in maintenance bypass mode, eliminating the risk of a redundant power source and protecting against hazardous energy.

Electrostatic Precipitator

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.
