Experience in Using a PFW System – A Case Study


A safety document management system, in a domain such as the power industry, is known as a Permit for Work (PFW) solution. It is based on the issues prevalent in an environment and on the methods available to eliminate potential safety issues. This paper considers how a PFW system should be implemented. It does so by identifying an appropriate case study from a domain not usually associated with PFW systems, and applying a suitable process, +PFW.
