摘要

This paper discusses the lessons gleaned from more than 5000 qualitative hazard evaluations completed by the authors and compatriots over the past 18-years. The learnings were from project risk reviews, management of change (MOC) risk reviews, full unit process hazard analyses (PHAs), and PHA revalidations. (All of these evaluations fall within the qualitative category of CCPS's "Hazard Identifications and Risk Assessments [HIRAs]," required in the Risk-Based Process Safety [RBPS] guide [CCPS, 2007].) The experience covers all chemical and related industry. The paper shares secrets that will speed up your hazard evaluations while not sacrificing thoroughness. Issues covered include: Should you project your notes during the meetings? Should you use dedicated software? Should you have a dedicated scribe? Should you define the methods and make sectionsodes ahead of the meetings? What methods should you choose and when? What documentation rules speed up the meeting? What facilitation rules speed up the meetings without crimping brainstorming? What mistakes kill brainstorming and also slow the meetings? Data based on thousands of PHAs is presented, along with a condensed set of optimization rules.
