1st step in treating lead poisoning remove the person from further exposure
7 Steps HUD Risk Assessment Process 1. determine appropriate evaulation process
2. obtain background information
3. schedule evaulation
4. conduct evaulation
5. determine actual & future hazards
6. provide guidance
7. produce a written report

abate measures include building component replacement; enclosure; paint removal by heat gun, chemical, or
contained abrasive; encapsulation (20 yr warranty), permanent soil covering; soil
removal and replacement
An abatement project has been scheduled in a 1950's house. no
Is a risk assessment required by Title X law

An abbreviated test can be performed when the owner agrees; all components tested are the same in each room equivalent; the
component tested is positive
for lead based paint in the first five rooms tested.

surface and is within three feet of the floor or ground
Advantages of Composite sampling lower cost per surface sampled; increased surface area that can be wiped for the same
cost;

Advantages of XRF testing are speed, cost-efficiency, non-destructiveness
After abatement the EPA requires what two items to be done post abatement visual inspection and dust sampling
in target housing and child occupied facilities?
ALARA As Low As Reasonably Achievable
