Permit to Work

A Permit to Work is a formal, written authorization that ensures maintenance tasks are carried out safely, especially when the job involves hazardous work such as electrical isolation, confined spaces, hot work, or working at heights. It outlines the job scope, risks, safety precautions, and responsible personnel before work begins. In maintenance management, PTW systems help control risks, avoid accidents, and ensure compliance with safety regulations. For technicians, it acts as a checklist and control measure—confirming that the right people, tools, and precautions are in place before starting critical maintenance activities.
