“The Action Level,” ○R 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
Continuance of Certification (COC) points, respectively,
for successful participation.
Participants must answer “The Action Level” ○R questions,
and return the completed answer sheet at the end
of that issue’s “The Action Level” ○R column. To earn the
designated CM or COC credit, a score of 70 percent
or better is required within a 12-month period. Certified
Industrial Hygienists and Certified Associate Industrial
Hygienists may earn 2 points per year. Certified Safety
Professionals may earn 1.2 points per year.
Enrollment is possible each month, but points are
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 threemonth
period. If you register in August 2011, you will
receive 0.5 CM points and/or 0.3 COC points after
you have completed answers sheets for August and
September 2011, and scored a 70 percent or better
average on them (only in your first quarter of enrollment,
if enrolling in the middle of the quarter, will you be
permitted to submit answer sheets for two months and
receive full credit; three answer sheets are required for
all other quarters). In the next quarter, you’ll receive
0.5 CM points and/or 0.3 COC points after satisfactorily
completing answer sheets for the October, November,
and December 2011 issues, and so on.
To enroll, complete the registration form and the answer
sheet at the end of this “The Action Level” ○R column.
The cost is $199 (ACGIH ○R /AIHA ○R members)/$219 (nonmembers)
for one year. Nonmembers are encouraged
to become members to take advantage of the member
discount. For more information regarding ACGIH ○R
membership, call 513-742-2020, or apply online at
http://www.acgih.org/members/memberform.htm.
Checks must be in U.S. currency, drawn on a U.S.
bank, and payable to ACGIH ○R . We also accept AmEx,
MasterCard, Discover, and Visa.
This continuing education program fee is separate
from the Journal subscription cost. The fee covers
administration costs, and is nonrefundable.
Submissions must be received by the date listed on
each answer sheet.

QUESTIONS 8(5)
Effects of Forearm vs. Leg Submersion in Work
Tolerance Time in a Hot Environment While Wearing
Firefighter Protective Clothing
Charles P. Katica, Robert C. Pritchett, Kelly L. Pritchett, Andrew
T. Del Pozzi, Gytis Balilionis, and Tim Burnham
1. In the article, the average WBGT temperature of the
environmental chamber was .
a. ∼ 30.8 ± 0.7 ◦ C
b. ∼ 35.2 ± 0.8 ◦ C
c. ∼ 32.8 ± 0.9 ◦ C
d. ∼ 37.2 ± 0.8 ◦ C
2. In the article, the overall findings found an increase of
following lower leg submersion in cool water.
a. 18%
b. 22%
c. 24%
d. 28%
Evaluation of Sampling Methods for Measuring Exposure
to Volatile Inorganic Acids in Workplace Air.
Part 1: Sampling Hydrochloric Acid (HCL) and Nitric
Acid (HNO3) from a Test Gas Atmosphere
Alan Howe, Darren Musgrove, Dietmar Breuer, Krista Gusbeth,
Andreas Moritz, Martine Demange, Véronique Oury, Davy
Rousset, and Michel Dorotte
3. When volatile acids such as hydrochloric acid and
nitric acid are sampled using a sodium carbonateimpregnated
quartz fiber filter and a prefilter, more
reliable estimates of exposure are obtained than when
the acids are sampled using a silica gel sorbent tube.
This is because volatile acids can be present in the
air in the form of both mist and vapor and, while filter
sampling methods typically collect the inhalable fraction
of airborne particles, silica gel tubes significantly undersample
acid mist droplets. True or False?
4. Measurement of exposure to volatile acids can be
subject to both positive and negative interference, even
if a prefilter is used, potentially leading to high or low
results. True or False?
Implementation of a Quantitative Real-Time PCR
Assay for the Detection of Mycobacterium immunogenum
in Metalworking Fluids
Glenn Rhodes, Alexandra Fluri, Andrea Ruefenacht, Marco
Gerber, and Roger Pickup
5. Quantitative real-time PCR assays detect .
a. DNA
b. antigens
c. RNA
d. enzymes
6. The term “cell equivalents” (CE) is used because
obtaining accurate cell counts of mycobacteria is difficult
due to what physiological feature?
a. slow growth
b. rapid growth
c. cell clumping
d. low cell densities
Personal PM2.5 Exposure Among Wildland Firefighters
Working at Prescribed Forest Burns in Southeastern
United States
Olorunfemi Adetona, Kevin Dunn, Dan Hall, Gary Achtemeier,
Allison Stock, and Luke P. Naeher
7. and are the chief occupational
woodsmoke inhalation exposures for wildland
firefighters.
a. Volatile organic compounds; carbon dioxide
b. Carbon monoxide; respirable particulate matter
c. Nitrogen oxides; ozone
d. Lead; benzene
8. Factors that may limit the utility of using carbon monoxide
as a proxy for respirable particulate matter exposure in
smoke from forest fires for wildland firefighters include:
a. Job task/location (i.e., working fire line on foot, driving
bulldozer, flying helicopter).
b. Exposure to emissions from trucks, mules (4wheelers),
and other vehicles used for managing and
fighting forest fires.
c. Time and location of sampling (i.e., sampling firefighters
at base camp for overnight exposures vs. sampling
firefighters at fire line during working/fighting
forest fires).
d. All of the above
Ice Cooling Vest on Tolerance for Exercise Under
Uncompensable Heat Stress
Glen P. Kenny, Andrew R. Schissler, Jill Stapleton, Matthew
Piamonte, Konrad Binder, Aaron Lynn, Christopher Q. Lan,
and Stephen Hardcastle
9. Aging is associated with a progressive decrease in the
physical work capacity and reductions in the capacity to
dissipate heat. Using a cooling vest would likely reduce
the level of thermal and cardiovascular strain to the
same extent, therefore resulting in a similar exposure
time in an older worker compared with a younger worker
performing a similar intensity work protocol. True or
False?
10. An ice cooling vest worn under the protective garment
was shown to increase exercise duration by ∼12%
compared with the protective garment-only condition, yet
D78 Journal of Occupational and Environmental Hygiene August 2011

the level of cardiovascular strain (as measured by heart
rate) at the end of the exercise was similar. This is likely
due to a greater sweat-induced reduction in central blood
volume associated with the longer duration of exercise
performed with the ice vest under the protective garment.
True or False?

Jérôme Lavoué
11. Which country does not have criteria for initiating cleaning
of nonporous ductwork?
a. France
b. Finland
c. Great Britain
d. United States
12. Under real conditions, which sampling method(s) of the
surface dust in the duct yield(s) the most accurate results
and the smallest standard deviation?
a. NADCA method
b. IRSST method
c. ASPEC method
d. NADCA and IRSST methods
