permit-to-work

A permit-to-work is a human-made formal authorization procedure that controls entry into and execution of hazardous work activities. It operates by requiring documented risk assessment, verification of controls, and explicit approval from an authorized person before work begins. The system persists through written permits (physical or electronic) that specify scope, hazards, controls, duration, and responsible parties, and through organizational policies that mandate their use. It is maintained by safety-management systems and enforced by organizational authority structures. [formal: permitum-laboris | substrate: behavior | horizon: generations | explicit: yes | epoch: 0.01]
