Firefighting Instructors’ Exposures to Polycyclic Aromatic Hydrocarbons During Live Fire Training Scenarios

Katherine M. Kirk and Michael B. Logan

1. Combustion products deposited onto and retained by structural firefighting ensembles during training include:

2. Potential routes of exposure to polycyclic aromatic hydrocarbons (PAHs) for firefighters wearing structural firefighting ensembles and self-contained breathing apparatus (SCBA) during training include:

Cardiac Strain Associated with High-rise Firefighting

Denise L. Smith, Jeannie M. Haller, Ron Benedict and Lori Moore-Merrell

3. When comparing the stair and elevator trials, both HRpeak and
HRmean were higher for fire suppression and search and rescue crews during the WORK phase in the stair trials. True or False?

4. The availability of elevators during high-rise fire operations would likely reduce cardiac strain to the largest degree for which work assignment?

Flow Characteristics and Spillage Mechanisms of an Inclined Quad-Vortex Range Hood Subject to Influence from Draft

Rong Fung Huang, Jia-Kun Chen and Jyun-Hua Lin
5. The leakage mechanisms of the IQV range hood are closely related to the flow characteristics. True or False?

6. When the range hood is influenced by a draft with a velocity larger than a critical draft velocity, the spillage of pollutants becomes significant. True or False?

An Empirical Model of Human Aspiration in Low Velocity Air Using CFD Investigations

T. Renée Anthony and Kimberly R. Anderson

7. Simulations of particles moving in low velocity environments identified that the fraction of particles 50 μm and larger that enter into the mouth and nose decreases with particle size but increases with increased breathing velocity. True or False?

8. In CFD studies, aspiration efficiency was found to exceed that of the current inhalable particulate mass (IPM) criterion through ~ 60 μm, but then was less than the IPM criterion of 50% for larger particles. True or False?

Modeling of Human Viruses on Hands and Risk of Infection in an Office Workplace Using Micro-Activity Data

Paloma I. Beamer, Kevin R. Plotkin, Charles P. Gerba, Laura Y. Sifuentes, David W. Koenig and Kelly A. Reynolds

9. The Healthy Workplace Project reduced infection risk. True or False?

10. The model was most sensitive to the frequency of hand contacts with surfaces. True or False?

Clothing Adjustments for Concealed Soft Body Armor During Moderate Physical Exertion

Greg A. Ryan, Stacy H. Bishop, Robert L. Herron, Charles P. Katica, Bre’anna L. Elbon, Andrew M. Bosak and Phillip Bishop

11. The findings of this study are applicable to Level II body armor, typical of law enforcement. True or False?

12. These data suggest that a WBGT adjustment of approximately 9 °C is necessary to ensure the safety of individuals wearing concealed Level II SBA at tested WBGTs. True or False?

A Comparison of Two Methods to Assess the Usage of Mobile Hand-held Communication Devices

Sophia Berolo, Ivan Steenstra, Benjamin C. Amick, III and Richard P. Wells

13. Studies such as this one investigating patterns of electronic device usage do not require human subjects (institutional review board) approval. True or False?

14. Self-reports of use on a typical day last week overestimated logged use. True or False?

Effects of Data Sparsity and Spatiotemporal Variability on Hazard Maps of Workplace Noise

Kirk Lake, Jun Zhu, Haonan Wang, John Volckens and Kirsten A. Koehler

15. Which is not called out as a pitfall attending hazard mapping?

16. If temporal variability were held constant, sparsity and amount of temporal sampling would be inversely related. True or False?
