Questions
Is a formal system in place to promptly address the findings and recommendations of
a PHA to ensure that the recommendations are resolved in a timely manner and that
the resolution is documented?

a. If so, are timetables established for implementation? 3
b. Does the system require that decisions concerning recommendations in PHAs
and the status of implementation be communicated to all operations,
maintenance, and other personnel who may be affected?
Is the methodology used in past PHAs and/or planned future PHAs appropriate for
the complexity of the process?
Are the PHAs being led by an individual who has been trained in the methods being
used?
Based on the most recent PHAs conducted, are the average rates of analysis
appropriate for the complexity of the systems being analyzed? (Typically, 2 to 4
P&IDs of average complexity will be analyzed per day.)
After the process hazards have been identified, are the likelihood and consequences
of the failure scenarios assessed using either qualitative or quantitative techniques?
