Process or system checklists can be used to evaluate equipment, materials or procedures during any of the significant phases of an installation’s life, i.e. design, construction, start-up, operation and shutdown. Checklists consist of key words or matters considered significant for the meaningful evaluation of procedures, equipment or materials used at the installation. Checklists should be subjected to regular auditing and updating and are generally limited to the experience of the checklist author.
