Frequently Asked Questions

What is a Trapped Key Interlock?

A trapped key interlock is a safety device applied to two or more movable parts, preventing hazardous operations unless predetermined safety conditions are met. The key is physically trapped until safe conditions are restored.

Why use a Trapped Key Interlock System?

To protect personnel from hazards by ensuring predetermined sequences of operations are followed. These systems prevent accidental startup of machinery during maintenance or access to dangerous zones.

How do Trapped Key Solutions work?

A trapped key interlocking solution consists of three defined actions: isolating hazardous energy, transferring the key to allow access, and requiring the key's return before energy can be restored.

Are PISANPRO products compliant with international standards?

Yes, our safety interlocks and systems are designed to meet or exceed international safety standards including ISO 14119, IEC 60947, and other relevant machinery safety directives.

Do you offer customization for specific applications?

Yes, we offer tailored interlock solutions and LOTO training systems based on client requirements, facility layout, and specific machinery configurations.
