Now take the PHL you made in part 1 of this case study and construct a detailed Preliminary Hazard Analysis (PHA) on each item on your PHL. Realize that the PHA takes what your brainstorming session came up with in the PHL and gets a little more into the weeds with such things as causal factors, consequences, and relative risk. These are the things you should focus on in a one to two-page report to your boss. Use the Risk Assessment Matrix to quantify the risks you identify.
