What is a machine guard interlock?

A machine guard interlock is a safety mechanism that ensures machinery stops operating when a guard is opened, removed, or not properly in place. It combines a physical guard with an interlocking device to prevent access to hazardous areas while the machine is running.

Key Features:

• Automatic Shutdown – Stops machine operation if the guard is breached.
• Prevents Restart – The machine cannot restart until the guard is properly closed or replaced.
• Safety Compliance – Meets OSHA and ISO requirements for safeguarding machinery.

Common Types:

• Mechanical Interlocks – Triggered by physical movement of the guard.
• Electrical Interlocks – Use sensors or switches to control machine power.

Purpose: Machine guard interlocks provide an active layer of protection, ensuring worker safety by eliminating access to hazardous areas during operation.
