CASE STUDIES:

Evaluating the Association of Workplace Psychosocial Stressors with Occupational Injury, Illness, and Assault
Lezah P. Brown, Kathleen M. Rospenda, Rosemary K. Sokas, Lorraine Conroy, Sally Freels and Naomi G. Swanson

1. As a result of this research one would conclude that
    occupational stressors such as poor interpersonal relationships
    cause occupational injuries. True or False?

True
False
2. When the data were analyzed by race, which racial minority
    category appeared to be over-represented in reporting
    occupational injuries, illnesses and assaults?
a. African American
b. Hispanic
c. Asian
d. Others
Particle Release from Respirators, Part I: Determination of the Effect of Particle Size, Drop Height and Load
Jeffrey S. Birkner, David Fung, William C. Hinds and Nola J. Kennedy

3. A direct correlation emerges in many cases between drop
    height and particle release from filtering facepiece respirators.
    True or False?

True
False
4. Flattening of particle release when a filtering facepiece
    respirator is dropped from increasing heights may be due to
    the respirator reaching a terminal velocity. True or False?
True
False
Particle Release from Respirators, Part II: Determination of the Effect of Tension Applied in Simulation of Removal
Jeffrey S. Birkner, Stephanie Kovalchik, David Fung, William C. Hinds and Nola J. Kennedy

5. A 4- to 6-pound lateral stretch applied to a filtering facepiece
    respirator appears to significantly increase the release of
    particles. True or False?

True
False
6. The lateral stretching of a filtering facepiece respirator was
    designed to simulate removal of a respirator from someone's head.
    True or False?
True
False
Evaluation of the Filtration Performance of NIOSH-Approved N95 Filtering Facepiece Respirators by Photometric and Number-Based Test Methods
Samy Rengasamy, Adam Miller and Benjamin C. Eimer

7. Filter penetrations for electrostatic filters will be higher
    for _________________.

a. nanoparticles (below 100 nm size)
b. particles larger than 100 nm size
c. particles larger than 1000 nm size
8. Nanoparticle concentration can be measured more accurately
    using a ____________________.
a. condensation particle counter
b. light scattering photometer
c. micro-balance
Comparison of Formaldehyde Exposure Levels in Two Multi-Industry Occupational Exposure Databanks Using Multimodel Inference
J. Lavoué, M. Gérin and R. Vincent

9. Which of the following best accounts for the incentive to
    evaluate the extra polation of exposure data across
    countries?

a. improved formaldehyde monitoring methods
b. advances in biostatistics
c. increase in international multi-center
          epidemiological studies of occupational
          hazards
d. lack of development of risk analysis tools
10. Both databanks provide a similar multi-industry portrait
      of formaldehyde exposure despite a potential for very
      different occupational settings. True or False?
True
False
