When implementing administrative controls for hazardous chemicals, what is the critical purpose of a 'permit-to-work' system for high-risk operations, as distinguished from standard operating procedures?

The critical purpose of a 'permit-to-work' system for high-risk operations involving hazardous chemicals, as distinguished from standard operating procedures (SOPs), is to ensure that specific, inherently dangerous tasks are performed only after a thorough risk assessment, authorization, and the implementation of all necessary safety precautions for that particular job. While Standard Operating Procedures provide general, routine instructions for safely handling chemicals in everyday situations, a permit-to-work system is a documented, formal authorization process designed for non-routine, high-hazard activities.
