Question 1 : Which of the following statement(s) is (are) TRUE regarding the impact of uncertainty and data quality?

Uncertainty stems from both natural variability and lack of knowledge.

Studies have shown that a high degree of uncertainty has relatively little impact on an overall exposure assessment.

Significant gaps in data will not affect the effectiveness of risk communication.

The contribution of variability-driven uncertainty is usually larger than that of lack-of-knowledge uncertainty.

Question 2 : Which of the following is TRUE about the risk decision-making process?

Professional judgment is usually not a factor.

Data is usually not available for a full quantitative risk assessment.

Control banding is a qualitative, matrix-based approach.

Risk matrices are generally of little value.

Question 3 : The federal organization that has published the MOST information on risk assessment is the ___________.

Occupational Safety and Health Administration

Department of Transportation

Nuclear Regulatory Commission

Environmental Protection Agency

Question 4 : Which of the following is the BEST description of risk?

Risk is the potential for exposure and is primarily related toxicity.

Risk involves the quantitative assessment of exposure.

Risk is the probability and magnitude of harm resulting from exposure to hazards.

Risk almost always involves a high degree of uncertainty.

Question 5 : Which of the following is an accurate definition of the field of industrial hygiene?

The anticipation, recognition, evaluation and control of factors that may impact the well-being of workers

The application of environmental factors applied to atmospheric hazards

The use of mathematical models applied to ergonomics

The use of personal protective equipment to reduce inhalation hazards

Question 6 : What are the elements of the risk-assessment paradigm? How can these elements be applied in a workplace setting in which an emergency responder is addressing a large spill of trichloroethylene? Describe how risk assessment can be used in industrial hygiene practice.

Your response should be at least 200 words in length.

Question 7 : In your own words, define risk. Identify the four risk functions and describe how these functions are used to make risk decisions. List the factors that influence the perceived acceptability of a risk. How can an industrial hygienist use these factors to determine how much risk is acceptable?

Your response should be at least 200 words in length.

Question 8 : Define instantaneous monitoring, integrated monitoring, personal monitoring, and area monitoring, and explain the differences among each one. Provide a scenario in which in each method would be used.

Your response should be at least 200 words in length.

Question 9 : Define exposure assessment, and describe the seven steps involved in an exposure-assessment strategy. Apply each step to a scenario where you, as an industrial hygienist, are asked to describe a worker's exposure to cadmium during a brazing operation.

Your response should be at least 200 words in length.
