CASE STUDIES:

Climate Change and Occupational Safety and Health: Establishing a Preliminary Framework
Paul A. Schulte and HeeKyoung Chun

1. This article indicated that climate change may result
    in increasing the prevalence, distribution and severity
    of known occupational hazards. True or False?

True
False
2. Products that are environmentally safe or "green" are
    not necessarily safe for workers. True or False?
True
False
A Comprehensive Review of the Literature on Exposure to Metalworking Fluids
Donguk Park, Patricia A. Stewart and Joseph B. Coble

3. In terms of generalizability of findings, this review will likely
    be considered least applicable to which of the following
    categories of industries?

a. automobile manufacturing
b. aircraft overhaul
c. automobile parts industry
d. small machine shops
4. From this work it would appear that the non-extractable
    mass in metalworking aerosols is independent of fluid type.
    True or False?
True
False
Occupational Exposure to Benzene at the ExxonMobil Refinery at Baton Rouge, LA (1977-2005)
Julie M. Panko, Shannon H. Gaffney, Amanda M. Burns, Ken M. Unice, Marisa L. Kreider, Lindsay E. Booher, Richard H. Gelatt, J. Ralph Marshall and Dennis J. Paustenbach

5. This dataset includes multiple limits of detection. True or False?

True
False
6. The job title(s) associated with each task bin influenced
    the exposure potential and was the primary determinant of
    exposure. True or False?
True
False
Estimation and Validation of Biomarker-based Exposures for Historical Ammonium Perfluorooctanoate
Kim H. Kreckmann, Carine J. Sakr, Robin C. Leonard and Barbara J. Dawson

7. Current jobs at the plant site were divided into three exposure
    categories (low, medium, and high) based on biomonitoring
    data from how many individuals?

a. 1948
b. 660
c. 1025
d. 6027
8. The consistently tight distribution of measured serum levels
    among individuals holding the same job enabled the creation of
    multiple narrow exposure categories. True or False?
True
False
Indoor Allergens in Minnesota Schools and Child Care Centers
Daniel C. Tranter, Amanda T. Wobbema, Kathleen Norlien and Dale F. Dorschner

9. Which material sampled had the highest concentrations
    of cat and dog allergens?

a. Carpet
b. Vinyl floor tile
c. HVAC filters
d. Upholstered furniture
e. Stuffed toys
10. Which maintenance or building factor is NOT listed as a
    factor that correlates with allergen concentrations?
a. Cleaning
b. Active soil depressurization
c. Outdoor air exchange
d. HVAC filtration
e. Use of HEPA vacuum cleaners
Elevated Cancer Mortality in a German Cohort of Bitumen Workers: Extended Follow-up through 2004
Thomas Behrens, Walter Schill and Wolfgang Ahrens

11. Which statement regarding the standardized mortality
      ratio (SMR) is correct?

a. The SMR is a ratio that can be used to
          measure temporal trends of mortality rates in a
          certain population.
b. The SMR is the ratio that compares the
          mortality of exposed subjects and unexposed
          subjects within a cohort.
c. The SMR is equivalent to the relative risk.
d. The SMR is the ratio between the observed
          number of deaths and the expected number
          of deaths based on age-, sex- and period-specific
          mortality figures of a reference population.
e. None of the above.
12. Which of the mechanisms stated below may have caused
      the observed increase of lung cancer mortality estimates
      in the cohort of asphalt workers? (Choose the correct
      combination of answers.)
  1. An increase of lung cancer mortality risk may be due to a higher smoking prevalence in this cohort of workers as compared to the general population.
  2. Smoking may act as a confounder when different occupational groups in the cohort show different smoking patterns.
  3. The higher lung cancer mortality risk may be due to occupational exposures such as inhalation of fumes from heated asphalt.
a. Only statement 3 is correct.
b. Only statements 2 and 3 are correct.
c. Only statements 1 and 3 are correct.
d. Only statement 2 is correct.
e. All three statements are correct.
Biological Markers of Carcinogenic Exposure in the Aluminum Smelter Industry, A Systematic Review
Nancy B. Hopf, Tania Carreón and Glenn Talaska

13. The urinary 1-hydroxypyrene biomarker is a measure of
      carcinogenicity. True or False?

True
False
14. In the aluminum industry, the pre-bake technology plants
      emit less PAHs than the Soderberg technology plants.
      True or False?
True
False
