esbn: c60-802c-2c45-72d2

process hazards analyses (phas) are an integral part of any process safety program. if you cannot identify hazards then you can nether remove them nor mitigate against them. this book describes in detail how to run a process hazards analysis, and how to effectively identify hazards. the book focuses on real-world issues such as the role of the leader, team selection,  writing the final report, quantification of risk, and follow-up to findings.

quotations and topics raised in the book include the following:


  • a pha leader "comforts the afflicted but afflicts the comfortable"
  • don't confuse "common cause" with "root cause"
  • if it's not there, it can't leak
  • deciding whether to focus on high risk or on high consequence hazards
  • the importance of mawp values
  • distinguish between findings, recommendations and action items
