Workplace thermal stress evaluation

QUESTION 1

Workplace thermal stress evaluation

1. 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.Your answer must be a minimum of 75 words in length.

QUESTION 2

1. 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.Your answer must be a minimum of 75 words in length.

QUESTION 3

1. 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.Your answer must be a minimum of 75 words in length.

QUESTION 4

1. 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.Your answer must be a minimum of 75 words in length.
2. Global warming will unquestionably increase the impact of heat on individuals who work in already hot workplaces in hot climate areas. The increasing prevalence of this environmental health risk requires the improvement of assessment methods linked to meteorological data. Such new methods will help to reveal the size of the problem and design appropriate interventions at individual, workplace and societal level.
