API RP 584

Description

The purpose of this RP is to explain the importance of IOW’s for process safety management and to guide users in how to establish and implement an IOW program for refining and petrochemical process facilities for the express purpose of avoiding unexpected equipment degradation that could lead to loss of containment. It is not the intent of this document to provide a complete list of specific IOW’s or operating variables that might need IOW’s for the numerous types of hydrocarbon process units in the industry (though some generic examples are provided in the text and in Appendix A); but rather to provide the user with information and guidance on the work process for development and implementation of IOW’s for each process unit.
