Lead Abatement Supervisor
Exam Questions and Answers| Latest Update| Guaranteed Pass
,Q1. What federal law provides the framework for regulating lead-based paint
activities, including abatement?
Answer: Title IV of the Toxic Substances Control Act (TSCA), specifically the
Residential Lead-Based Paint Hazard Reduction Act of 1992.
Rationale: TSCA Title IV directed EPA to establish standards for lead-based paint
activities, training, certification, and work practices, codified in 40 CFR Part 745.
Q2. Which EPA regulation establishes certification and training requirements for lead
abatement supervisors?
Answer: 40 CFR Part 745, Subpart L (the Lead-Based Paint Activities Rule).
Rationale: Subpart L sets the training, certification, and work-practice standards for
individuals and firms conducting lead-based paint activities, including abatement
supervisors.
Q3. What is the difference between "lead abatement" and "interim controls"?
Answer: Abatement is intended to permanently eliminate lead-based paint hazards,
while interim controls are temporary measures that reduce exposure.
Rationale: HUD guidelines distinguish abatement (permanent hazard elimination,
e.g., removal, enclosure, encapsulation) from interim controls (temporary risk-
reduction measures such as paint stabilization and specialized cleaning).
Q4. Under EPA rules, what defines a "target housing" unit subject to lead-based paint
regulations?
Answer: Housing built before 1978, excluding housing for the elderly or disabled
(unless a child under 6 resides there) and zero-bedroom units.
Rationale: 40 CFR 745.103 defines target housing based on the 1978 federal ban on
residential lead-based paint use, with specific exemptions.
Q5. What are the current EPA dust-lead hazard standards for floors and window sills?
Answer: Dust-lead hazard levels are at or above 10 micrograms per square foot on
floors and 100 micrograms per square foot on window sills.
Rationale: EPA lowered these dust-lead hazard standards in 2021 under 40 CFR
745.65 to better protect children from lead-dust exposure.
, Q6. What is the CDC blood lead reference value used to identify children with elevated
lead exposure?
Answer: 3.5 micrograms per deciliter, updated in 2021 from the previous value of 5
micrograms per deciliter.
Rationale: CDC uses this reference value to identify children with higher lead
exposure than most children, prompting case management and environmental
investigation.
Q7. Who must be present on-site during lead abatement work?
Answer: A certified lead abatement supervisor.
Rationale: EPA and state regulations require a certified supervisor to be on-site to
direct abatement workers, ensure work-practice compliance, and oversee
containment and cleanup.
Q8. What training must an individual complete to become a certified lead abatement
supervisor?
Answer: Successful completion of an EPA-accredited (or state-accredited) initial
Abatement Supervisor training course, typically four days in length.
Rationale: Accredited training providers must teach the required curriculum under 40
CFR 745.225, covering health effects, regulations, abatement methods, and safe work
practices.
Q9. How often must a lead abatement supervisor complete refresher training to
maintain certification?
Answer: Generally every three years.
Rationale: 40 CFR 745.225 requires periodic refresher training so supervisors stay
current on regulatory changes and safe work practices.
Q10. What OSHA standard governs worker exposure to lead in construction activities,
including abatement?
Answer: 29 CFR 1926.62, the Lead in Construction Standard.
Rationale: This standard sets the permissible exposure limit, action level, exposure
monitoring, medical surveillance, and respiratory protection requirements for
construction workers exposed to lead.
