"The Action Level!®"
— Current Quiz


Edited by J. Thomas Pierce, PhD, CIH (1980-2012), DABT (Retired)

“The Action Level!®, a self-study, continuing education program, provides a convenient and interesting opportunity for individuals to expand their knowledge in relevant areas of industrial hygiene, as well as occupational and environmental safety and health. The program is approved by both the American Board of Industrial Hygiene, and the Board of Certified Safety Professionals, which award Certification Maintenance (CM) points and recertification points, respectively, for successful participation.

Participants must read each issue of the Journal, answer “The Action Level!® questions, and return the completed answer sheet at the end of that issue’s “The Action Level!® column. To earn the designated credit, an average score of 70 percent or better is required within a 12-month period. Certified Industrial Hygienists and Certified Associate Industrial Hygienists may earn up to 12 contact hours per year. Certified Safety Professionals may earn up to 1.2 recertification points per year.

Credit is awarded only four times each year—in March, June, September, and December—to participants who score an average of 70 percent or better within each three-month quarter. To earn credit in any quarter, participants must satisfactorily complete answer sheets for all three months of that quarter.

The program is based on a calendar year and subscriptions running from January 1 to December 31 are available to participate in
 “The Action Level!® program. New participants in the program can enroll at any time, but their enrollment fees will be prorated by the number of quarters they are eligible to participate. 

To enroll, click here,  read about the program and click on “register” to complete your registration.  The cost is $219 (ACGIH®/AIHA members)/$249 (nonmembers) for one calendar year running January 1 to December 31. Prorations are available for new participants who purchase after January 31.  Nonmembers are encouraged to become members to take advantage of the member discount. For more information regarding ACGIH® membership, call 513-742-2020, or apply online.  

This continuing education program fee is separate from the Journal subscription cost. The fee covers administration costs, and is nonrefundable. 

Answers must be received by the date listed at the end of each quiz.

Workplace Exposure to Particulate Matter, Bio-accessible, and Non-soluble Metal Compounds during Hot Work Processes

Balázs Berlinger, Ulf Skogen, Conny Meijer and Yngvar Thomassen

1. Which one of the investigated metals seemed to be the most bio-accessible (most soluble in an artificial lung lining fluid) of the workplace aerosols in this study?




2. The possible health effects of Cr(III) and Cr(VI) compounds are quite different, therefore suggesting investigations covering multiple scenarios. True or False?

Modelling of Exposure to Respirable and Inhalable Welding Fumes at German Workplaces

Benjamin Kendzia, Dorothea Koppisch, Rainer Van Gelder, Stefan Gabriel, Wolfgang Zschiesche, Thomas Behrens, Thomas Brüning and Beate Pesch

3. Which of these time periods approximates this study?



4. Which of the following is NOT a good explanation for differences in WEMs for the historical cohort and findings from this analysis?


Occupational Survey of Airborne Metal Exposures to Welders, Metalworkers, and Bystanders in Small Fabrication Shops

Allison L. Insley, Joshua R. Maskrey, Laura A. Hallett, Rachel C.D. Reid, Erin S. Hynds, Christopher Winter and Julie M. Panko

5. Cadmium and copper appeared to be the two metals with the highest exceedance fractions compared against a variety of benchmarks such as the TLV-TWA and REL. True or False?

6. The primary impact of this work would be expected in active working populations of production welders. Results like these are best applied to:



Size, Composition, Morphology, and Health Implications of Airborne Incidental Metal-containing Nanoparticles

Natalia I. Gonzalez-Pech, Larissa V. Stebounova, Irem B. Ustunol, Jae Hong Park, T. Renee Anthony, Thomas M. Peters and Vicki H. Grassian

7. Results from this work generally suggested that a good initial method would likely use:



8. At least for the machining center, the distribution shapes of the three metals were for the most part similar with both methods, FP-XRF or ICP-MS. True or False?



Deadline for answers is June 30, 2019.
