Unit VII Journal Instructions Evaluate two to three tasks that you perform on a regular basis that include repetitive motions. Summarize how you would determine the level of risk for developing a musculoskeletal disorder (MSD) and what controls could be used to reduce the risk. Unit VII Project Instructions Read the background information in Section I. Your paper should address each of the subsections of Section II. Make sure you read each section completely and carefully before preparing your paper. Section I: Background Acme General Contractors is the general contractor for a new 20-story commercial building in downtown Centerville, USA. The building will use a rigid-frame structure and reinforced concrete construction. A major subcontractor on the project who will be performing the roofing and interior insulation and drywall installation has hired you as the safety officer. Section II: Assignment Analyze the hazards associated with the roofing and the interior work. You should identify at least three hazards for each activity. Perform a risk assessment on three of the hazards that you identified for each activity (six total) using the 4 X 5 matrix shown in Figure 34-1 on page 492 of the textbook or in the quantitative risk assessment form, which can be accessed by clicking  here . Prioritize the need for controls for the hazards that you selected based on the results of the risk assessment. Using the hierarchy of engineering controls listed in Figure 3-3 on page 29 of the textbook, recommend a control method for each hazard that you believe would be the most effective in reducing risk to an acceptable level. Explain why you made the choice, and support your decisions with at least one reference other than the textbook. Use the 4 X 5 matrix or the quantitative risk assessment form to show the reduction in risk for each hazard after the control method has been applied. For any fall protection that you recommend, be specific about the type of fall protection needed. Discuss how Prevention through Design (PtD) could be used to reduce the risks associated with these operations. Prepare your project in a properly formatted APA document including a title page, the body of the paper, and a references page. The body of your paper must be a minimum of four pages in length and be double-spaced; the title page and references page will not count toward meeting the four-page minimum requirement. You must use your textbook and at least one other source outside of the textbook as references. Unit VIII Journal Instructions How will you be able to apply what you learned in this course to your current or future work? QUESTION 1 Discuss the interrelationship between safety managers and safety engineers. In your discussion, include the roles and responsibilities of each, and give at least two examples of when the two professions interact with each other.Your response must be at least 200 words in length.QUESTION 2 As the safety engineer, you have determined that a project is required to drastically reduce the cost of injuries. The project will cost $10,000. Your company's financial controller has required that all potential projects have a return on investment (ROI) analysis before approval. She has asked that you present an analysis showing the cost reduction for the following 3 years of implementation. Assume a 3% inflation rate in your calculation. Assume a value for injury cost savings. Show all work, and make certain that your discussion that follows meets the minimum word requirement.Your response must be at least 75 words in length.QUESTION 3 A local construction company has had a recent injury that involves minor medical treatment at a cost of $500 in total direct costs. As the safety manager, you have been asked to calculate the cost of this injury to determine the volume of business needed to cover this loss (cost). Once you calculate the cost, you should discuss what impact it has on the business. Assume a 4% profit margin. Show all work, and make certain that your discussion that follows meets the minimum word requirement.
