This document should be used in conjunction with a process safety publication such as ’HAZOP: Guide to best practice’ (available from IChemE) or ‘Guidelines for Hazard Evaluation Procedures’ (available from CCPS). 4.0.1 Team The Commissioning Manager is responsible for the completion of study 4 with or without the assistance of site or project resources as appropriate. 4.0.2 Timing Hazard Study 4 should be completed prior to the introduction of process materials, or the commencement of operations, whichever is the sooner.

Regular visits to the plant during construction can surface concerns at a time when they can be addressed with the least possible impact on the schedule. 4.0.3 Documentation The Commissioning Manager should arrange for the addition of relevant documents to the Project SSHE dossier (worksheet j). A list of outstanding actions should be produced and added to the dossier. HAZARD STUDY 4: APPLICATION The following sections 4.1 and 4.2 describe how to conduct Hazard Study 4. 4.1 METHOD This study will require many actions to be carried out by a number of people, all coordinated by the Commissioning Manager, and will not normally involve many formal meetings. Use of the Hazard Study 4 worksheet (worksheet r) will help the Commissioning Manager ensure that a thorough check of the installation is achieved.
