Question 1
Compare and contrast the different control methods that are commonly used for ionizing radiation.
Question 2
Discuss the differences between ionizing and non-ionizing radiation. Provide one example of an occupational exposure to ionizing radiation and one to non-ionizing radiation. How do the differences influence the control methods used for these two types of radiation?
Question 3
Compare and contrast three methods of noise control. Which control method would you recommend for controlling exposure to a fan motor producing an eight-hour TWA noise exposure to an operator at 92 dBA?
Question 4
Summarize the standards and guidelines published by OSHA, the ACGIH, and NIOSH that can be used to evaluate airborne exposures to hazardous materials. What are some weaknesses to the permissible exposures limits (PELs) currently enforced by OSHA?
Question 5
Compare two methods used to evaluate an employee's inhalation exposure to a hazardous material. Which method do you believe provides the most accurate measure of an employee's exposure?
Question 6
Discuss how anthropometric data is used in designing controls on a machine like a metal press. What are some safety considerations when deciding to design controls for the press for the 90th percentile versus the 95th percentile? What are some important variables to consider if the press requires more than one control that require independent actions by the operator?
Question 7
Compare and contrast the use of grounding/bonding, fuses/circuit breakers, GFCIs, and double insulation for protection against electrocution while using a machine in a wood shop. Of the methods, which do you believe provides the most protection? Would you recommend the use of a combination of the methods? Why or why not?
