4. conduct evaulation
5. determine actual & future hazards
6. provide guidance
7. produce a written report
abate measures include - ANS-building component replacement; enclosure; paint removal
by heat gun, chemical, or contained abrasive; encapsulation (20 yr warranty), permanent soil
covering; soil removal and replacement
accessible surface - ANS-surface that protrudes from the surrounding area to the extent that
a child can chew the surface and is within three feet of the floor or ground
Advantages of Composite sampling - ANS-lower cost per surface sampled; increased
surface area that can be wiped for the same cost;
Advantages of XRF testing are - ANS-speed, cost-efficiency, non-destructiveness
After abatement the EPA requires what two items to be done in target housing and child
occupied facilities? - ANS-post abatement visual inspection and dust sampling

Allowable amount of lead in dry surface paint wit hXRF - ANS-1.0mg/cm2
allowable lead in water - ANS-15 ppb or 15mg/L
allowed quantity of lead in dry surface paint with paint chip testing - ANS-5000ppm = 5% by
weight
An abatement project has been scheduled in a 1950's house. Is a risk assessment required
by Title X law
before work begins? - ANS-no
An abbreviated test can be performed when - ANS-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.
Are lead inspections mandatory in pre 1978 housing? - ANS-NO
ASTM - ANS-American Society for Testing and Materials

stain varnish or shellack has been applied to and have a common substrate
Bypass Hazard Identification - ANS-determine if all lead-based paint hazards have been
controlled after the work has been completed

, Certian adjacent building compenents can be grouped together if? - ANS-They have the
same building history

Composite samples should only be collected from where? - ANS-bare floors, carpeted floors,
window sills, window troughs, exterior surfaces
Contract law - ANS-relates to situations in which a person breaks or breaches a legally
enforcable written contract
De minimis levels "safe work practices" must be used during stabilization or abatement only
when the area of paint being disturbed is greater than: - ANS-20 ft2 on exterior, 2ft2 on
interior surface, or 10% of a building component surface area
Deciliter - ANS-a metric measure of volume equal to one-tenth of a liter. Less than a half cup
Deteriorated paint - ANS-any interior or exterior paint that is peeling, chipping, chalking, or
cracking, or is located on an interior or exterior surface or fixture that is damaged or
deteriorated
disadvantages of composite sampling - ANS-information on specific location is lost;
laboratories will have to adopt special handling and digestion procedures
Disclousure requirements - ANS-required for pre 1978 housing for buyer or seller with EPA
apporved pamphlet and disclosure of LBP or LBP hazards. They have 10 days to then
coduct a risk assesment or inspection
dust clearance for floors - ANS-40 ug/ft2
dust clearance for outside concrete - ANS-800 ug/ft2
dust clearance for wells - ANS-400 ug/ft2
dust clearance window sills - ANS-250ug/ft2
Dust wipe media must meet what criteria? - ANS-ASTM E 1792 laboratory criteria
Errors and Omissions Insurance - ANS-Insurance which financially protects an architect
against claims for damages resulting from professional negligence. Also called professional
liability insurance.
Exposure to radiation is affected by 3 important factors - ANS-time, distance, and shielding
Fair Paint Condition - ANS-Exterior less than or equal to 10 ft2
Interior less than or equal to 2 ft2
small surface components less than or equal to 10% total surface area damaged
final dust wi[e sample is reported in what? - ANS-ug/ft2
For 1960-1977 homes how many units are needed and what percentage will you use to not
use chart? - ANS-1000 or more and multiply by 0.029 2.9%
For paint chip sampling what PPE should you have? - ANS-respiratory protection with
combination filter p100 and vapors
For pre- 1960 homes how many units are needed & what percentage will you multiply to not
use a chart? - ANS-over 1040 and multiply by 5.8% 0.058
Four functions of final risk assessment report - ANS-1. summarize results by indicating
where hazards are foundTDS
2. indicates range of hazard control options likely to be effective
3. includes all raw data and identifying information
4. in some jurisdictions becomes a legal document
