CASE STUDIES:

Comparison of Surface Wipe Media for Sampling Lead on Hands
Mark Boeniger

1. According to ASTM 1792-03 regarding quantitative specifications
    for wipe medium used for sampling for surface lead dust, it provides
    minimum requirements for: a) size, b) moisture content, c) tensile
    strength, d) absolute sampling efficiency.

a. all of the above
b. a and d
c. b and d
d. b and c
2. One way to increase the absolute collection efficiency of hand-wipe
    sampling, as discussed in the article, is to:
a. apply more pressure when sampling, thus getting
          more frictional removal
b. wet the hands first and rub with a little soap, and
          then wipe
c. composite more than one wipe per sample
d. rub longer
Case Study for Underground Workers at an Electric Utility: How a Research Institution, University and Industry Collaboration Improved Occupational Health Through Ergonomics
Amy Stone, Debra Usher, Richard Marklin, Patricia Seeley and Janice Yager

3. The initiative described in the article is different from other
    collaborations among a research institution, a university
    and an employer in that laboratory testing is used to validate
    ergonomic recommendations. True or False?

True
False
4. Which of the following were lessons learned from the initiative in
    the article:
a. It is important to have strong support from
          management.
b. It is necessary to have hourly workers on the
          ergonomics team.
c. Applications engineers should attend the
          ergonomics team meetings.
d. The team leader needs to ask team members to
          complete simple assignments between meetings.
e. All of the above.
Controlled Study of Mold Growth and Cleaning Procedure on Treated and Untreated Wet Gypsum Wallboard in an Indoor Environment
Michael Krause, William Geer, Lonie Swenson, Payam Fallah and Coreen Robbins

5. According to this study, how long did it take for visible mold growth
    to occur on any wet wallboard panel?

a. 8 hours
b. 24 to 48 hours
c. one week
d. three weeks
6. Moldy wallboard could be dried, cleaned of mold growth, and coated,
    such that tape lift samples collected on the surfaces afterward were
    negative. True or False?
True
False
Sensitization to Airborne Molds and Its Health Effects in Peat Moss Processing Plant Workers
Anne Mériaux, Yvon Cormier, Pascal Pageau, Evelyne Israël-Assayag and Caroline Duchaine

7. Molds responsible for HP in peat moss plant workers:

a. are present in unharvested peat
b. result from heating during the processing process
c. usually grow after bagging
d. only affect smokers
8. Dust removal systems usually operational in peat plants:
a. offer adequate protection by eliminating most of
          the dust
b. actually increase health risk by eliminating only
          the non-respirable dust
c. may have some effect but do not prevent
          sensitization to molds
d. could be improved by decreasing air turnover rate
          within the processing plant
Bioaerosols in Peat Moss Processing Plants
Anne Mériaux, Pascal Pageau, Yvon Cormier, Nicole Goyer and Caroline Duchaine

9. Airborne dust levels are good indicators of airborne moulds
    and bacteria in peat moss processing plants. True or False?

True
False
10. The lack of correlation between peat (solid material) microbial
      content and airborne contamination by moulds is explained
      by the huge impact of the dust removing system on air quality.
      True or False?
True
False
