Your response should be at least 300 words in length.

Question 2

Discuss in detail the quantitative risk evaluation technique, including both cut-set probabilities of system failure and the economics management theory equation of expected values.

Your response should be at least 300 words in length.

Unit IV Case Study

Instructions

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.

Access the CSB website and download the Chemical Spill Contaminates Public Water Supply in Charleston, West Virginia final report using the instructions from the unit lesson in the study guide, or click here.

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. Click here for an example of an APA style paper.

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 20 posed questions. If you can develop more than 20, 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 20 identified hazards that you recognized from each posed question. Attempt to cite as many controls as possible, even using textbooks from previous safety or environmental classes that you may have already taken from CSU.

Be sure to include your abstract (page 2 of your paper) and a references page (the last page of your paper). The CSU Citation Guide is a great source to assist with properly formatting your paper, in-text citations, and general references in APA style. Contact the CSU Writing Center for examples of references not included in the Citation Guide:teamsucceed@columbiasouthern.edu

Be sure to write all questions (“What-If” Analysis/Safety Checklist) and statements (Potential Controls) with proper grammar and punctuation.

Unit VII Project

Instructions

Step 1: Select only ONE of the following two options:

Option 1: Design a system safety program plan for one of your own organization’s work systems, or for an organization with which you are familiar.

Option 2: Design a system safety program plan for a bulk tank railcar off-loading facility for hydrocarbon products that has the following features:

one railcar switch located next to an interstate highway,

capacity to off-load liquid hydrocarbon products,

two 500,000 gallon bulk liquid storage tanks for liquid hydrocarbon products,

two diaphragm pumps with piping between the off-loading station and the bulk liquid storage tanks,

one off-loading station (single-sided) that is elevated 12 feet from the ground, and

one switch engine for staging railcars at the off-loading station and at railcar storage tracks.

Step 2: Then, using the CSU APA style example paper as a formatting guide (including title page, abstract, body, and reference page) linked here, include the following:

Design a minimum of a seven page system safety program plan with a minimum of five scholarly sources (books and articles, and at least one from the CSU Online Library) using the following level one headings:

Defined Objectives

System Description

Hazard Identification

Hazard Analysis

Risk Evaluation

Hazard Controls

Verification of Controls

Risk Acceptance

Safety Control Structure Diagram (see these instructions in the paragraph below)

Planned Periodic System Review

Design a safety control structure diagram for your work system, and embed it within your system safety program plan as the content for your ninth level one heading. Use Figure 6.2 on page 193 in your textbook of an ammonia fill station as an example. Notice that the designed controls within this example structure are the level indicators, control valves, and relief valves.
