Lead Paint Inspection & Risk Assessment Flashcards

Under HUD's Lead Safe Housing Rule, what is the threshold for activities that require full lead-safe work practice documentation (interior)?

Answer: 6 sq ft per room

Activities disturbing more than 6 square feet per room of interior LBP-containing surfaces trigger full lead-safe work practice requirements including containment, HEPA cleanup, and clearance.

A risk assessor collects a soil sample from a bare play area in a pre-1978 housing complex. Laboratory results show 450 ppm of lead. What does this indicate?

Answer: The soil exceeds the EPA action level for play areas (400 ppm) and is a lead hazard requiring remediation

The EPA action level for lead in soil in play areas is 400 ppm. A result of 450 ppm exceeds this threshold and constitutes a lead soil hazard requiring remediation.

What credential must a person have to legally conduct lead abatement in a federally assisted property?

Answer: EPA certification as a lead abatement contractor firm using certified abatement workers or supervisors

Lead abatement in federally assisted housing must be performed by EPA-certified (or state-certified in authorized states) lead abatement firms using certified lead abatement workers or supervisors.

Which of the following best describes 'enclosure' as a lead hazard control method?

Answer: Covering lead-based paint with a rigid material that cannot be penetrated, creating a permanent barrier

Enclosure is an abatement method that permanently covers lead-painted surfaces with rigid materials (drywall, paneling, vinyl siding) that cannot be penetrated under normal use.

When performing lead dust wipe sampling for a clearance examination, which surfaces must always be sampled?

Answer: Floors in each room where work was performed, window sills, and window wells (troughs)

Clearance dust wipe sampling must include floors, window sills, and window wells in each room where lead hazard reduction activities were performed.

Under HUD's Lead Safe Housing Rule, what must a PHA do when a child under 6 in HCV housing is identified as having an elevated blood lead level (EBLL)?

Answer: Conduct an environmental investigation and hazard reduction in the unit within required timeframes

When an EBLL is identified in a child in HCV housing, the PHA must conduct an environmental investigation to identify lead hazard sources and perform hazard reduction, following HUD's required protocols.
