Quiz____?
Lead-based paint (LBP) -
Answer✓✓
Any varnish, shallac, or coating that contains either- 1.0 mg/cm2 - 0.5 % by weight - 5000 ppm -
Older instruments could not read accurately at 0.7, so the lead standard was updated to 1.0
Quiz____?
Dust sample clearance values -
Answer✓✓
- Floors: 40 μg/ft2 > 10 μg/ft2 (10 μg/ft2 in NY) - Windows: 250 μg/ft2 > 100 μg/ft2 (50 μg/ft2
in NY) - Window wells (troughs): 400 μg/ft2 (100 μg/ft2 in NY) - Samples must be at 1 sq ft > 2
sq ft (can be reduced to 1 sq ft if within 10 μg)
Quiz____?
EPA Soil Regulations -
1
, Answer✓✓
- 400 ppm for playgrounds/children's areas - 1200 ppm for rest of yard - There must be 9 sq ft
of soil to classify with soil testing - At 5000 ppm, MUST remediate/abate (remove & replace,
paving, or bioremediation)
Quiz____?
Lab sampling technique -
Answer✓✓
- AAS (Atomic Absorption Spectrometry) - Sample is placed into a furnace and vaporized ...
light is shone through to give a quantitative result
Quiz____?
XRF -
Answer✓✓
- X-ray fluorescence - Utilizes radioactive isotopes (unstable material trying to reach stability) -
Cobalt-57 (half-life of 9 months) and cadmium-109 (half-life of 15 months) are the two sources
(where radiation originates) - Emits gamma rays but will read X-rays (backscatters) - Ionizing
radiation from the removal of electrons due to interactions with radiation
Quiz____?

, LBP Hazard -
Answer✓✓
ANY condition that causes exposure to lead
Quiz____?
LBP inspection -
Answer✓✓
a surface-by-surface investigation to determine the presence of lead
Quiz____?
CPSC -
Answer✓✓
- Consumer Product Safety Commission - Set a lead paint standard: cannot contain 0.06% lead
by weight ... updated to 0.009% - The commission banned lead-based paint in 1978
Quiz____?
True/False: Dust sampling only done for hazard assessments -
Answer✓✓
True; only risk assessors take samples to determine likelihood of coming into contact with
contaminants

Quiz____?
HUD Guidelines for abatement -
Answer✓✓
Must last 20 years. Includes the following procedures: - Removal - Enclosure - Replacement -
Encapsulation Painting over is a temporary fix!
