Question 1
If an XRF reading is 0.8 mg/cm2 on all tested locations, classification?
Correct Answer:
Negative.
Explanation:
In lead paint assessments, the XRF screening uses an action level of 1.0 mg/cm2. If a reading is at or above this level, the surface is considered to contain lead-based paint (positive). If a reading is below 1.0 mg/cm2, it is not considered lead-based paint above the threshold (negative). Since the measurement is 0.8 mg/cm2 at all tested locations, every reading is below the action level. Therefore, the surfaces are classified as negative for lead-based paint.
Question 2
Deteriorated paint is defined as which of the following?
Correct Answer:
Interior or exterior paint that is peeling, chipping, chalking, or cracking, or damaged or deteriorated surfaces
Explanation:
Deteriorated paint means the coating has lost its integrity—the interior or exterior paint is peeling, chipping, chalking, or cracking, or the surface beneath is damaged or deteriorated. These conditions show the paint film is no longer intact and can expose hazards if disturbed, which is why this option best fits the definition. Fresh and recently applied paint is still in good condition, fading but intact means the film remains sound despite color change, and paint on surfaces that aren’t accessible doesn’t by itself indicate deterioration—the focus is on actual damage to the coating.
Question 3
Interim control measures are designed to
Correct Answer:
Temporarily reduce human exposure to LBP hazards.
Explanation:
Interim control measures are temporary steps to lower people’s exposure to lead-based paint hazards while long-term remediation is planned or carried out. They focus on limiting contact with lead dust and chips, and preventing dust from spreading, so occupants aren’t exposed during the interim period. These are not meant to permanently eliminate the hazard or remove soil—that requires permanent abatement or remediation—and they aren’t about allowing unrestricted occupancy; if needed, access and activities are temporarily restricted to reduce exposure. Examples include isolating the work area, sealing or enclosing hazards, wet cleaning, and using barriers and HEPA cleaning to control dust.
Question 4
E-1727 indicates which type of sampling criteria?
Correct Answer:
Soil Sampling Criteria
Explanation:
Media-specific sampling criteria are organized by the sampling medium. E-1727 is the designation used for soil sampling criteria, guiding how soil samples are collected when assessing lead hazards. This includes where to sample (areas where children play and around foundations), how deep to collect (to capture the surface soil most likely to be contacted), and how many samples to combine to obtain a representative result. The other media have different criteria codes, so referencing E-1727 points to soil rather than air, dust, or paint chips. That’s why soil sampling criteria is the correct interpretation.
Question 5
HUD disturbance is considered when the area is more than how many square feet (interior and exterior)?
Correct Answer:
2 ft2 Interior / 2 ft2 Exterior
Explanation:
HUD disturbance is about when renovation work disturbs lead-based paint enough to require lead-safe practices. The trigger is a disturbance of more than 2 square feet on interior surfaces or more than 2 square feet on exterior surfaces. This small threshold is used to prevent the spread of lead dust during common home repairs. So, the correct threshold is 2 square feet both inside and outside. Disturbances exceeding this limit call for containment, proper cleanup, and lead-safe work procedures. The other numerical options represent thresholds from different regulatory contexts and do not define HUD disturbance in this setting.
