Healthcare Workers’ Knowledge, Perceptions and Behaviors Regarding Antineoplastic Drugs: Survey from British Columbia, Canada

Chun-Yip Hon, Kay Teschke and Hui Shen

1. None of the healthcare job categories examined in the study were afraid of working with antineoplastic drugs. True or False?

2. According to the authors, which healthcare job categories in particular require training regarding the risks of exposure to antineoplastic drugs?

Patrol Officer Daily Noise Exposure

Lynn R. Gilbertson and Donna J.H. Vosburgh

3. Based on the study sample, the normalized 8-hour TWA noise exposure for patrol officers was well below the OSHA limits or ACGIH® recommendations. True or False?

4. Based on study data, which occupational responsibilities resulted in the highest noise exposure?

Statistical Modeling of Occupational Exposure to Polycyclic Aromatic Hydrocarbons Using OSHA Data

Derrick G. Lee, Jérôme Lavoué, John J. Spinelli and Igor Burstyn

5. Equation (2) mentioned in the article by Lee et al. indicates that the denominator represents the number of minutes in a standard work day. Why is using a set constant potentially problematic?

6. Estimating exposure levels based on industry alone is insufficient. Estimating by occupation will always be better because exposure is homogeneous within jobs. True or False?

An Evaluation of the Physiological Strain Experienced by Electrical Utility Workers in North America

Robert D. Meade, Martin Lauzon, Martin P. Poirier, Andreas D. Flouris and Glen P. Kenny

7. What proportion of workers exceeded the American Conference of Governmental Industrial Hygienists (ACGIH®) upper limit core temperature for acclimated workers (38.5°C)?

8. In which work category were the greatest levels of thermal and cardiovascular strain observed, including the two individuals who achieved core temperatures of ~39.5°C?

Penetration of Combustion Aerosol Particles through Filters of NIOSH-certified Filtering Facepiece Respirators (FFRs)

Shuang Gao, Jinyong Kim, Michael Yermakov, Yousef Elmashae, Xinjian He, Tiina Reponen and Sergey A. Grinshpun

9. The protection level offered by an N95 respirator filter against NaCl particles can be used to accurately predict the protection provided by this filter against combustion particles. True or False?

10. An N95 filter used in disposable respirator facepieces can offer better protection when challenged with combustion particles. True or False?

Experimental Measurements of Near-source Exposure Modeling Parameters

C.B. Keil

11. Motion in the “near zone” does not affect the parameters producing the exposures of workers working in close proximity to a vapor source. True or False?

12. Pollution transport parameters in areas close to a vapor source are uniform throughout a room. True or False?

Hand Self-wiping Protocol for the Investigation of Lead Exposure in the Workplace

Jean-Philippe Gorce and Martin Roff

13. Which of the following best describes the output of both wipe and wash sampling techniques?

14. Hand sampling relying upon wiping by an industrial hygienist would generally be regarded as more practical, time efficient and less costly than self-wiping. True or False?

A Field Study on the Respiratory Deposition of the Nano-sized Fraction of Mild and Stainless Steel Welding Fume Metals

L.G. Cena, W.P. Chisholm, M.J. Keane and B.T. Chen

15. Order from greatest to least the fraction collected is:

16. The NRD sampler estimates the aerosol’s nano-fraction deposited in the respiratory system. True or False?
