Lead metric: permit to work checks performed to plan and permit to work non-conformance

Overview

Dr Zsuzsanna Gyenes, IChemE Safety Centre and Carolyn Nicholls, RAS Limited discuss the IChemE Safety Centre’s supplementary publication on Lead Metrics: Permit to Work.

A supplementary publication to the IChemE Safety Centre Guidance Document “Lead Process Safety Metrics – selecting tracking and learning 2015” was published by the ISC. This guidance note is intended to provide context for the Lead Metric “Permit to work checks performed to plan” and “Permit to work non-conformance” and expand on those metrics. This guidance should be used to help identify suitable performance metrics for your system. It aims to define the key elements of a PTW and suggest metrics that can be used to help monitor the performance of your PTW system.

The document sets out general phases in the lifecycle of a PTW, and identifies potential metrics for each phase and typical elements of a PTW but is not intended to provide a model for development of a PTW system.
