CASE STUDIES:

When and Why Do Experts Perform Exposure Measurements? An Exploratory Study of Safety Engineers, Work Environment Inspectors, and Occupational Hygienists
Anita E. Pettersson-Strömbäck, Ingvar A. Bergdahl, Bengt G. Järvholm and Steven Nordin

1. Decisions other than the choice of sampling strategy influence
    the possibility to use measurement data to estimate exposure.
    True or False?

True
False
2. What was the common criterion for all expert groups in this study?
a. No other perceived cause of symptoms
b. Expectation of certain levels
c. No common criterion
Toxigenic Fusarium spp. as Determinants of Trichothecene Mycotoxins In Settled Grain Dust
Anne Halstensen, Karl-Christian Nordby, Sonja Sletner Klemsdal, Elen Oleif, Per-Erik Clasen, Eduard Wijnand

3. What was the preferred method for detecting closely related
    Fusarium species in grain dust?

a. Cultivation
b. Microscopy
c. PCR
4. Which one of the following PCR assays is most relevant for
    detecting Fusarium species that produce DON, T 2 or HT 2?
a. tri5 PCR
b. F. avenaceum PCR
c. F. langsethiae PCR
Developing a Health and Safety Plan for Hazardous Field Work in Remote Areas
Michael Gochfeld, Conrad D. Volz, Joanna Burger, Stephen Jewett, Charles W. Powers and Barry Friedlander

5. A formal Health and Safety Plan (HASP) document is required for
    all field activities. True or False?

True
False
6. HASPs are required by HAZWOPR for hazardous waste sites, but
    not for general field operations, such as scientific expeditions. A
    formal written HASP for field operations in a remote area should:
a. Identify all tasks and potential hazards
b. Delineate lines of stop work authority
c. Detail the use of personal protective equipment
d. Allow for iterative modification if field conditions
         change
e. All of the above
A Preliminary Study on Gram Negative Bacteria (GNB) and Their Endotoxins in a Gin House
P.B. Doctor, L.J. Bhagia A.Y. Derasari, J.B. Vyas, R.J. Amin and S.K. Ghosh

7. Byssinosis is a disease found among:

a. Newspaper refusal workers
b. Grain processing workers
c. Cotton textile mill workers
d. Cattle shed workers
8. LAL test stands for:
a. Lymphocytes Amoebocytes Lysate
b. Limulus Amoebocytes Lysate
c. Listeria Auto Lysate
d. Laws and Labor Welfare
Correlation Between Airflow Patterns and Performance of Laboratory Fume Hood
Li-Ching Tseng, Rong Fung Huang, Chih-Chieh Chen and C.-P. Chang

9. A methodology of hood testing based on the single point breathing
    zone sampling appropriately reflects the reality of the hood leakages
    induced by the separation of turbulent boundary layers, unsteady
    motions of shear layers, vortical flows, wake instabilities, and
    interactions among these characteristic flow structures. True or
    False?

True
False
10. Due to the aerodynamic deficiencies induced by the design
      principles of the conventional fume hood, the contaminant
      leakages may commonly be found around the side poles, doorsill,
      bottom of sash, and operator's chest, where the separation of
      turbulent boundary layers, unsteady motions of shear layers,
      vortical flows, wake instabilities, and interactions among these
      characteristic flow structures would most likely happen. True
      or False?
True
False
Evaluation of Source Model Coupled Computational Fluid Dynamics (CFD) Simulation of the Dispersion of Airborne Contaminants in a Work Environment
S.M. Salim, Shekar Viswanathan and Madhumita Bhowmick Ray

11. The method for sampling and analysis of the concentration of
      isopropyl alcohol in air is described in:

a. NIOSH 1460
b. NIOSH 1400
c. NIOSH 1401
d. NIOSH 1402
12. Generally, CFD simulations indicate that indoor airflow patterns
      are: i) three dimensional; ii) well mixed; iii) turbulent flow; or
      iv) recirculating
a. (i) only
b. (i), (ii) and (iii) only
c. (i), (ii) and (iv) only
d. (i), (ii), (iii) and (iv)
A Comparison of the Postdeployment Hospitalization Experience of U.S. Military Personnel Following Service in the 1991 Gulf War, Southwest Asia After the Gulf War, and Bosnia
Besa Smith, Tyler C. Smith, Margaret A.K. Ryan, and Gregory C. Gray

13. Compared with veterans of the 1991 Gulf War, service members
      deployed to southwest Asia after the Gulf War were at increased
      risk for postdeployment hospitalization for a mental disorder.
      True or False?

True
False
14. Service members deployed to which theater experienced the
      lowest risk of hospitalization across broad disease condition
      categories?
a. Service members deployed to southwest Asia
          following the 1991 Gulf War
b. Service members deployed to Bosnia
c. Veterans of the 1991 Gulf War
