The underside of a horizontal surface which projects beyond a wall line, such as
an overhanging roof.
What is a soffit?
False
T/F: The risk assessor should be involved in the process of selecting a contractor.
1. There are big cracks in the walls.
2. Ceiling is leaking in the bathroom and the kitchen.
3. The window wells are in disrepair- and contain paint chips.
4. Right across the street there's a battery recycling shop.
Scenario: You arrive on premises and are scheduled to conduct a visual assessment of
the property. Which do you take note of?
A risk assessment determines the Lead Hazards and An EBL investigation focus
on where the child has been and the cause or causes of exposure.
What's the difference between a risk assessment and an EBL child investigation
To determine and report the existence, nature, severity, and location of lead paint
hazards and potential remedies
The objective of a Risk Assessment is:
A surface by surface investigation for determining the presence and location of
lead based paint and report the results
What is the definition of a Lead Inspection:
- Condition of paint
- various pathways (dust and soil)
- Future plans (maintenance and rehabilitation)
A Risk Assessor must consider the following factors in addition to the concentration of
lead in paint:
A supplement to
A Risk assessment is best described as _________ the approach of lead paint
Inspection and Abatement.
In good condition
A Lead Hazard screen is a type of Risk assessment that applies to housing that is:
- Determining the most appropriate evaluation process and obtaining background
information
- Conducting the evaluation and determining the actual hazards
-Providing guidance toward reducing and eliminating lead hazards and producing
a written report
The Risk Assessment process developed by HUD include:
- Collect background information on the number of similar units in the
development, the construction date, and the number of children in each unit
,- Collection information on the management and maintenance of the units within
the development
Before conducting a Risk Assessment, the Risk Assessor should:
Deteriorated paint, friction and impact surfaces, areas that have been mouthed by
a child, bare soil and accumulated dust.
The Visual Assessment identifies:
<10%
The condition of fair for interior components with small surface areas would have
______ of deterioration:
Paint that is loosened or broken because of impact
Chipped paint is defined as:
Chewing on lead contaminated components
Children are most commonly poisoned by:
<10 square feet
The condition rating of fair for exterior components with large surface areas would
have______of deterioration.
It is relatively simple and inexpensive and Current EPA, HUD and State standards
are based on wipe sampling
Dust Wipe sampling is recommended sampling method for most routine risk
assessment because:
250 ug/ft2 (micrograms/square foot)
EPA defines a "dangerous level of lead" in household dust from window sill as:
40 ug/ft2 (micrograms/square foot)
The HUD standard for a "dangerous level of lead" in household dust on an uncarpeted
floor surface is:
Does not tear easily but is easy for laboratory to digest (ASTM E1972)
Wipe material should meet the following criteria:
- Need to be analyzed by a laboratory from a sample typically referred to as a
Blank" to assure wipes are not contaminated prior to use.
- Should be less than 5 ug (micrograms/wipe
Background levels if contamination on dust wipes:
a third wipe pass that focusing on the corners - EPA
When wiping a floor surface for dust lead collection, the last wipe pass is:
S
Wipe samples generally are collected by wiping side-to-side in an ______ shaped
pattern
True
If the paint chips adhere to the wipe sample they should be included as part of the
sample
- hard floor surfaces and carpeted surface (separate)
- each different component tested (separate)
- and use a new wipe for each spot sampled.
The Risk Assessor should collect separate composite in a dwelling from:
A centrifuge tube or other hard shelled container
Wipe sample should be sent to a laboratory in:
400 ppm for high contact play area (400 ug/g)
, What is the lead level standard in bare soil areas in a play area to be considered a lead
hazard by EPA
1200 ppm (ug/g)
What is the lead level standard in bare soil for the rest of the yard:
At least 2 to 6 feet apart
Samples collected in a non-play areas of a building should be spaced:
X grid
Samples collected from small patches or play areas with bare soil should be collected
along an _____ shaped grid.
The soil is completed covered by grass or pavement
Soil samples need not be collected if:
3 to 10
EPA recommends _______ subsamples (aliquats) for each composite sample:
the top 1/2 inch
EPA recommends ________ of soil to sent to the laboratory for the purposes of a risk
assessment:
>1.0 ug/cm2 (milligrams/square centimeter)
The definition of a "dangerous level" of lead in paint when using an XRF analyzer
according to the HUD Guidelines is:
4 composite samples
How many dust wipe samples should be collected for a composite sample:
A visual inspection of the work area for dust and debris
Before conducting dust clearance sampling after renovation what needs to be conduct:
Re-clean and retest
What happens if a clearance test fails:
The total amount of dust on a specific surface area.
What does Dust Wipe measure:
Lead loading
What is the measurement of a wipe called:
at least 1 hour
How long must you wait after final cleanup is completed and visual inspection is passed
before collecting samples
0.5%
A lab result of _____ by weight indicated lead based paint in dry film.
All layers of paint
Collected Paint chip samples generally should include:
True
T or F The Risk Assessor should sample all deteriorated painted surfaces
15 ppb
The EPA National Primary Drinking Water regulations for Lead, established a "safe"
drinking water level at:
Water sampling is not a routine part of the Risk Assessment
The following statement is true concerning water sample:
2 composite samples (floor and window)
How many dust wipe samples should be collected in a Lead Hazard Screen:
Soil and water
