Answer to Question 1

ANS: C
Controlling physical agents, such as noise, can usually be accomplished through engineering strategies and personal protective equipment. It is much harder to change biological agents (bac-teria), chemical agents (aerosols), and psychosocial agents (burnout).

Answer to Question 2

ANS: C
It is true that chronic exposure to low-level doses of workplace chemicals below standards con-stitutes a potential health risk. Most chemicals have not been studied epidemiologically to deter-mine the effects of exposure on humans. As a consequence of general environmental contamina-tion with chemicals from work, home, and community activities, a variety of chemicals have been found in the body tissues of the general population. Predicting human responses to chemical ex-posures are complicated because multiple chemicals often combine and interact to create a new chemical agent.
