Guidance on permit-to-work systems : a guide for the petroleum, chemical and allied industries

This document describes good practice in the use of permit-to-work systems, and as such may be useful to operators using permit-to-work systems as part of a demonstration that risks have been reduced to as low a level as reasonably practicable (ALARP). The guidance is applicable to the onshore and offshore petroleum industry, onshore chemical and allied industries and other industries where permit-to-work systems are used. The document is primarily written around well-established paper-based permit-to-work systems, but where possible it accounts for the newer medium of electronic-based permit-to-work systems.
