Question 1 (25 points): Work-Related Musculoskeletal Disorders (WMSDs)
Many employees are complaining about discomforts, pains and cramps caused mainly from inadequate postures and repetitive motions during work activities. Later these warning signs will reveal Work-Related Musculoskeletal Disorders (WMSDs).
a) (10 Points) Describe in detail the consequences if a company didn't manage properly the risk factors related to WMSDs. (Cite two appropriate references).
b) (15 Points) Recommend ten actions for companies to control risks related to WMSDs.
(Cite two appropriate references).
Question 2 (40 Points): Upper Limb Disorders (ULDs)
Upper Limb Disorders (ULDs) include aches and pains in the shoulders, arms, wrists, hands, and fingers, as well as in the neck. (ULDs) are not restricted to one specific class of workers, or group of industrial employees, but are common in the workforce. a) (10 Points) List ten types of jobs that very likely cause ULDs.
b) (20 Points) Identify all potential causes of ULDs (Cite at least two appropriate references). Select 3 causes and explain why these three causes are the most critical according to you?
c) (10 Points) Construct the cause-effect diagram for ULDs. (See Figure 1).
Figure 1 Cause-Effect diagram
Question 3 (35 points): Workstation Improvements for E-Learning
Office workers are exposed to repetitive motion, primarily hand and wrist motion. In this exercise, you will improve your E-Learning workstation to avoid all potential Musculoskeletal risks related to office workers.
a) (7 Points) Describe all tasks that you are doing in your working environment for E-learning. (Things that may be part of your set up are: chair, desk, shelf, keyboard shelf, laptop, external mouse, external keyboard, or tablet with keyboard, or desktop computer with keyboard screen mouse, pens pencils, notebook, books, etc. ).
b) (8 Points) Identify the synovial joints that you are using in the ELearning workstation. Identify their types, and their dimensions of movements.
c) (20 Points) Complete the below Table 1 about the analysis of your working posture in E-Learning workstation. Recommend your improvement in the column of risk control options (See
Table 1).
