About this course
A permit to work (PTW) system is the formal, written process that stands between a high-risk task and the moment work actually begins. Rather than a single regulation, PTW is a widely used industrial safety control framework — common across manufacturing, oil and gas, and utilities — that ensures no non-routine or hazardous job starts until hazards have been identified, risk controls are in place, and the right people have reviewed and signed off on the work.
In food manufacturing, a PTW system typically acts as the umbrella process that ties together the specific permits already required for individual hazards, such as a hot work permit for welding and cutting, a confined space entry permit, or a lockout/tagout procedure for isolating equipment. The PTW system defines who can request work, who can review and approve it, what conditions must be verified before the permit is issued, and how the permit is closed out once work is complete. Done well, it creates a clear record of accountability and coordination before, during, and after a job — reducing the chance that two crews unknowingly create a hazard for each other, or that work proceeds before a hazard control is actually in place.
This course is written for all workers who may request, perform, or authorize non-routine or high-risk work, including maintenance staff, contractors, supervisors, and anyone who signs off on a permit before work begins. It's a useful companion to task-specific training such as hot work, confined space entry, and lockout/tagout, since PTW is the process that ties those individual controls together on a single job.
After completing this course, learners will be able to explain the purpose of a permit to work system, identify the types of tasks that typically require a permit, describe the roles involved in requesting, approving, and closing a permit, and recognize how PTW coordinates with other hazard-specific permits used on the same job.
