CASE STUDIES:

The Life-Saving Effectiveness of Body Armor for Police Officers
Tom LaTourrette

1. When shot in the torso, a police officer not wearing armor
    is ___ times more likely to be killed than if wearing armor.

a. 1.2
b. 3.4
c. 6.7
d. >10
2. Approximately ___ police officers in the U.S. are not required
    to wear body armor.
a. 29,000
b. 108,000
c. 236,000
d. 417,000
Removal and Leakage of Environmental Tobacco Smoke from a Model Smoking Room
Man-Pun Wan, Chi-Li Wu, Tsz-Tung Chan, Christopher Y.H. Chao and Lam-Lung Yeung

3. The sorption/desorption of some constituents of environmental
    tobacco smoke (ETS) on surfaces delays the removal of ETS
    by ventilation in indoor environments. True or False?

True
False
4. Which of the followings is NOT a strategy for ETS leakage
    prevention from smoking rooms?
a. full physical separation
b. maintain negative pressure
c. use swing-type door
d. no air recirculation
e. use sliding door
Inhalation Exposure to Jet Fuel (JP8) Among U.S. Air Force Personnel
Kristen W. Smith, Susan P. Proctor, Al Ozonoff and Michael D. McClean

5. Time spent in the airplane hangar during the workshift was
    found to have a significant effect on inhalation exposure to
    total hydrocarbons among fuel systems maintenance workers.
    True or False?

True
False
6. While a priori assigned high, moderate, and low exposure
    groups were useful in distinguishing JP8 exposure levels, job
    task based categories were found to be the most informative
    surrogate for exposure. True or False?
True
False
Mapping Particulate Matter at the Body Weld Department in an Automobile Assembly Plant
Sa Liu and S. Katharine Hammond

7. In order to use particle mapping to assess the effect of
    ventilation countermeasures in the reduction of particle
    concentrations, mapping should be conducted:

a. one time before and one time after
          countermeasures.
b. two times before and two times after
          countermeasures.
c. based on temporal variations and feasibility.
8. Because resistance welding is less hazardous compared
    to MIG welding, emissions from resistance welding operations
    do not need to be controlled. True or False?
True
False
Remediating Office Environments of Spore-forming Bacteria
Luke Johnson, Myron L. Smith, Melissa Begin, Bruce Fraser and J. David Miller

9. List three benefits of remediating office environments of
    spore-forming bacteria.

a. Reduces microbial load in the building.
b. Removes settled dust and dirt.
c. Improves the success of any subsequent
          biocide application.
d. Prevents the spread of the contamination
          and risk to the health of the workers by
          reducing the re-suspension of dust.
e. None of the above
f. All of the above
10. List three challenges associated with this remediation
      technique.
a. Difficult to discriminate between existing
          strain versus the ones introduced by malicious
          contamination.
b. Sampling technique can affect the enumeration
          of recovered cells.
c. The failure of the analytical technique to detect
          viable but non-culturable spores may affect
          interpretation of the data.
d. For the identification of B. anthracis, the different
          heat treatment regimes used can significantly
          influence culturable cell counts.
e. None of the above
f. All of the above
Occupational Carbon Monoxide Poisoning in Washington State, 2000-2005
Carolyn K. Reeb-Whitaker, David K. Bonauto, Stephen G. Whittaker and Darrin Adams

      percentage of workplaces had recurrent carbon monoxide
      exposures?

a. < 1%
b. 1–5%
c. 6–10%
d. > 10%
12. During the period 2000–2005, which of the following was
      not recorded in Washington workers' compensation data?
a. carbon monoxide poisoning incidents
b. individual claims
c. carbon monoxide overexposures
d. fatalities
