What does the term 'safety circuit' mean in inspection contexts?

In the context of inspection, the term 'safety circuit' refers to circuits that are specifically designed to include emergency stop functions and other safety features to protect individuals and equipment during operation. These circuits are crucial in ensuring that, in the event of a malfunction or hazard, the system can be shut down quickly and safely to minimize risk to personnel and equipment.

Safety circuits often have specific requirements for redundancy and reliability, meaning they are engineered to remain operational under fault conditions. Compliance with safety standards and regulations necessitates that these circuits be carefully inspected and tested to ensure they function correctly and can effectively mitigate potential dangers. This distinguishes them from other types of circuits that may prioritize efficiency or normal operation without built-in safety mechanisms.
