Discussion:
Thinking about the organization where you are currently employed or one where you have been employed in the past, what are some of the musculoskeletal disorders that are/were most commonly seen? What are some methods that you can think of that might prevent or might have prevented such disorders?
Q1: Summarize the three readings that are used for the wet bulb globe temperature (WBGT) evaluation of thermal stress in the workplace. Explain what each of the three measurements assesses about thermal stress, and discuss how the readings are evaluated using the two WBGT formulae.
Q2: Provide a definition and a brief explanation of each of the following meters, and detail how each meter might be used to evaluate physical hazards in the workplace: dynamometer, accelerometer, and goniometer.
Q3: Briefly describe the method you would use to evaluate the risk of a musculoskeletal disorder (MSD) at an operation where a worker on an assembly line uses a pneumatic screwdriver to repetitively insert a screw into a door panel. Discuss how your method can affect the accuracy and precision of your data.
Q4: Briefly discuss the difficulties associated with the evaluation of non-ionizing radiation sources. Summarize the methods that can be used for the evaluation of non-ionizing radiation in the workplace. Include a statement as to which method you believe would be the most reliable for evaluating infrared radiation exposures, and discuss how your method can affect the accuracy and precision of your data.
