Guide
2 ways to describe the amount of lead in dust: - ------------ANS: 1: Loading
2. mass concentration
5000ppm is the same as.. - ------------ANS: 1.0 mg/cm2
0.5% by weight

be abated by the firm for which they work, if they... - ------------ANS: Notify the client
in writing

B. Risk Assessment
C. Lead Hazard Screen - ------------ANS: B. Risk Assessment
A wipe sample you took came back from the lab with a lead result of 800ppm. What
should you do?
,A. This paint is lead-based paint, note in your report and let the client know they
have a lead paint in their property.
B. Resample the area where you took the sample from.
C. Call the lab and tell them they must report the results in mg/cm2
D. This paint is not lead-based paint, note the results in your report and let the client
know. - ------------ANS: D. This paint is not lead-based paint, note the results in your

(LBP is greater than 5000ppm)
Acceptable Dust Wipe criteria: 3 - ------------ANS: - does not contain aloe
- yields between 80% - 120% recovery rates
- blank wipes are less than 5 ug/wipe
advantages and disadvantages of composite wipe sampling: 2 each - ------------ANS:
Advantages:
-lower cost per sample
-increased surface area per wipe
Disadvantages:
-lead dust in a specific location info is lost
-labs must adopt special prep procedures
At what lead blood level does a child require chelation therapy? - ------------ANS: At
or above 45ug/dL
, at what time in the inspection do you collect blank samples? - ------------ANS: after

Describe the dust wipe sampling method in steps: 4 - ------------ANS: 1. Start at
