Castell's approach to working with customers is deeply rooted in understanding safety issues in modern industrial environments. Awareness of how security affects operation itself is an important step in creating systems that provide fast and secure access while maintaining efficiency and performance.

The Trapped Key Interlocking system ensures that the specified process is followed and cannot be circumvented or shortened in any way. Controlled key transmission ensures that wherever personnel move, whether starting or shutting down, they can be sure they are safe.

There are three simple steps to ensuring security in designing a key trap::

1. what you need to isolate / disconnect
   
2. how many access points to secure
   
3. what type of access is required.

The first key is used to start the process and remains trapped while the machine is running. The only way to remove the key is to isolate the danger by turning off the device. This key is then used to access the hazardous area and will remain trapped as long as the gate or door is open. The key can only be removed when the gate or door is closed. In this way, the key is either trapped when the machine is running and access is not allowed, or the key is trapped while access is allowed and the machine cannot be started.
