True
False
2. Which factor contributes to the number of viable pathogens that
    are transferred from environmental surfaces to the eyes/nostrils/
    lips via hand contact?
a. the concentration of viable pathogens on
          environmental surfaces
b. the rate of hand contact with environmental
          surfaces
c. the rate of hand contact to the eyes/nostrils/lips
d. the rate of pathogen die-off on the hands
e. all of the above

    undergo homogeneous nucleation at sufficient rates to produce
    SiO2 aerosol nanoparticles. True or False?

True
False
4. Differential mobility analyzers (DMA) classify particles according
    to which of the following?

b. drag forces only
c. the product of electrostatic and drag forces
d. a balance between electrostatic and drag forces
Measurement of the Physical Properties of Aerosols in a Fullerene Factor for Inhalation Exposure Assessment
Yuji Fujitani, Takahiro Kobayashi, Keiichi Arashidani, Naoki Kunugita and Kouji Suemura

5. Typically, nanoparticles (d < 100 nm) in the air have a high
    particle volume concentration, but have a low particle number
    concentration compared to coarse particles (d > 2000 nm).
    True or False?

True
False
6. The Scanning Mobility Particle Sizer (SMPS) measures:
a. aerodynamic equivalent diameter
b. electrical mobility equivalent diameter
c. diffusion equivalent diameter

Don Lofgren

7. Which one of the following choices best describes what was
    lacking among more than 90% of inspected worksites where
    workers wore respirators in response to airborne overexposures?

a. OSHA posters
b. respirator fit testing
c. recordkeeping
d. respirator storage containers
e. isoamyl acetate
8. Health care clinics with workers exposed to bloodborne
    pathogens were in compliance with requirements for
    ___________ but lacked _____________.

c. training/sharps with engineered sharps injury
          protection
d. sharps with engineered sharps injury
          protection/training

Phenyl Mercuric Acetate (PMA): Mercury-Bearing Flexible Gymnasium Floors in Schools – Evaluation of Hazards and Controlled Abatement
Harry Beaulieu, Chris Brown and Jeff Brown

9. When a 3-M Tartan® brand floor is actively disturbed, as
    with removal of the floor from a concrete slab, the workers can
    routinely be exposed to mercury vapor in excess of the OSHA
    PEL of 100 µg/m3. True or False?

True
False
10. When a 3-M Tartan® brand floor is actively disturbed as
      in the work of removal of the floor from a concrete slab,
      biological monitoring for mercury should be performed with
      what media?
a. Hair
b. Blood
c. Urine
Evaluation of the pDR-1200 Real-Time Aerosol Monitor
Kaila Benton-Vitz and John Volckens

11. The pDR 1200 aerosol monitor is an appropriate device
      for measuring 'inhalable' aerosol concentrations.
      True or False?

True
False
12. The pDR 1200 aerosol monitor should be field calibrated to
      each workplace aerosol encountered, as the factory calibration is
      not robust. True or False?
True
False

      lists. True or False?
True
False
