Question 1: Of the seven bullets listing the process hazard analysis tools, which tools, if
any, have you used in the past? Which tools would you consider more appropriate for
preliminary engineering design meetings, and which tools would you consider more
appropriate for more detailed engineering meetings, leading to the design of a work system
in your industry? Explain your response in detail. 200 words no references.

Question 2: Immediately following the Chemical Safety and Hazard Investigation Board’s
(CSB) published investigation report of the chemical spill into the Charleston, West Virginia,
public water supply, you have been contracted as a safety engineer consultant to evaluate
the investigation report from a system safety engineering perspective. As a macro-level
evaluation of the past event, you have been asked to help the CSB understand what
hazards may have been prevented if the bulk chemical tank owners had utilized a safety
management system (SMS) with system safety engineering inherent in the SMS design.
You will present a complete case study of just the six numbered statements within the
“Technical Analysis” section on page 28 of the report.
Chemical Spill Contaminates Public Water Supply in Charleston West Virginia final report
Using an APA style paper format (title page, abstract page, body with level 1 headings for
each section, and a references page), submit a three-page case study. The title and
reference page will not count toward the page count requirement.
Make your first level 1 heading “Summary of the Accident Report.” Summarize the “1.0
Executive Summary: Incident Description,” found on page 1 of the CSB report.
Make your second level 1 heading “What-If Analysis/Safety Checklist.” Using any or all of
the Appendices A, B, and C, include the what-if analysis/safety checklist technique
described in the Unit IV Lesson to evaluate the six paragraph statements on page 28 of the
“Technical Analysis” section of the report. Simply number each posed question that you
form. You must have at least 23 posed questions. If you can develop more than 23, please
do so. This will only enhance the quality of the process safety analysis.
Make your third level 1 heading “Potential Controls.” Being careful to follow the hierarchy of
controls described in the unit lesson, propose a control for each of the 23 identified hazards
that you recognized from each posed question. Attempt to cite as many controls as
Be sure to include your abstract (page 2 of your paper) and a references page (the last
page of your paper).
Be sure to write all questions (“What-If” Analysis/Safety Checklist) and statements (Potential
Controls) with proper grammar and punctuation (4 pages) 2 references.
