What is the primary purpose of an interlock in machine guarding?

The primary purpose of an interlock in machine guarding is to ensure that the machine is not operated in unsafe conditions. Interlocks are safety devices designed to prevent the machine from functioning unless certain conditions are met, usually to protect the operator from hazards associated with the machine's operation. For instance, an interlock may prevent a machine from starting if a safety guard is not securely in place, thereby reducing the risk of injury.

This safety mechanism acts as a crucial control measure, ensuring that individuals cannot inadvertently expose themselves to dangerous moving parts or other hazardous conditions. The core function of an interlock aligns closely with safety protocols, aiming to minimize risks associated with machinery operation.
