CASE STUDIES:

Characterizing Inward Leakage in a Pressure-Demand Self-Contained Breathing Apparatus
Rodney A. Bryant and Amy Mensch

1. The only requirement for inward leakage in a pressure-
    demand SCBA is below-ambient pressure inside the
    facepiece. True or False?

True
False
2. What is the assigned protection factor (APF) for a pressure-
    demand SCBA with a full facepiece?
a. 1,000
b. 2,000
c. 10,000
Effects of Liquid Cooling Garments on Recovery and Performance Time in Individuals Performing Strenuous Work Wearing a Firefighter Ensemble
Jung-Hyun Kim, Aitor Coca, W. Jon Williams and Raymond J. Roberge

3. What kind of cooling was used in the research and what
    temperature was used?

a. Liquid cooling garments with water at 18°C
b. Phase change materials at 10°C
c. Ice packs at 0°C
4. Cooling significantly improved the performance time within
    these study conditions. True or False?
True
False
Impact of Three Biological Decontamination Methods on Filtering Facepiece Respirator Fit, Odor, Comfort, and Donning Ease
Dennis J. Viscusi, Michael S. Bergman, Debra A. Novak, Kimberly A. Faulkner, Andrew Palmiero, Jeffrey Powell and Ronald E. Shaffer

5. How many respirator models demonstrated a statistically
    significant reduction in fit after decontamination using moist
    heat (MHI)?

a. 0
b. 2
c. 6
6. During the 2009 H1N1 influenza outbreak in the United States,
    multiple respirator manufacturers, U.S. public health agencies,
    and worker safety organizations recommended decontamination
    of filtering facepiece respirators for purposes of reuse. True or
    False?
True
False
Comparison of Workplace Protection Factors for Different Biological Contaminants
Kyungmin Jacob Cho, Tiina Reponen, Roy McKay, Alok Dwivedi, Atin Adhikari, Umesh Singh, Rakesh Shukla, Susan Jones, Gordon Jones and Sergey A. Grinshpun

7. The sensitivity of analytical methods for different contaminants
    to detect low inside concentration can affect the level of WPFs
    obtained at the tested workplace. True or False?

True
False
8. Which statement correctly explains the association between
    WPFs and the concentration of the contaminant outside
    the respirator?
a. Always highly correlated with each other
b. Never correlated with each other
c. Correlated with each other depending on
          the concentration of the contaminant outside
          the respirator
Exposure Assessment in Auto Collision Repair Shops
Anca Bejan, Lisa M. Brosseau and David L. Parker

9. In the collision shops participating in this study, painters
    and painter helpers were more likely to perform more sanding
    operations than the body technicians. True or False?

True
False
10. In this study, body technicians' noise exposures were above
      the OSHA PEL. True or False?
True
False

Jennifer S. Pierce, Steven E. Lacey, Julia F. Lippert, Ramon Lopez and John E. Franke

11. Which one of the following would not be identified as a
      likely factor affecting virus survival?

a. Lipid envelope
b. Viral size
c. Experience of surgeon
d. Virus diameter
12. Knowing the category of laser used for ablation irrespective
      of lesion provides a straightforward means of assessing
      chemical contaminant risk. True or False?
True
False
