Organization of a Hazards Analysis: Time Required, Kick-Off, Closeout and Walk Abouts

This post is the fourth in a paid series to do with the organization of a Process Hazards Analysis. The first four posts are:

• Organization

• The Charge Letter

• Preparations

• Documentation Requirements

In this post we discuss the time required, kick-off and closeout meetings, and walk abouts.

Time Required

A simple and convenient method of estimating the time needed for an analysis, and then measuring the progress of that analysis, particularly a HAZOP, is to count the number of P&IDs to be analyzed. The number of P&IDs to be analyzed can be used in two ways: first, to estimate the time required for a HAZOP, and second, to track progress during the study. While not all P&IDs are equally complex, this metric provides a useful planning and monitoring tool.
