Question 1
Under the EPA Renovation, Repair, and Painting (RRP) Rule (40 CFR 745), a firm
performing renovation work that disturbs painted surfaces in pre-1978 housing must
hold which certification?
A. OSHA 10-Hour Construction certification
B. EPA RRP Firm certification
C. NYC Department of Health lead abatement contractor license only
D. HUD Housing Quality Standards inspector certification
Correct Answer: B
Rationale: The EPA RRP Rule requires firms to be EPA-certified and use a certified
renovator on site. Distractor A is general safety training, not RRP-specific. Distractor C is
a separate NYC requirement but does not replace EPA firm certification. Distractor D is
for housing inspections, not renovation work.
Question 2
Under NYC Local Law 1 of 2004 (Lead Poisoning Prevention), paint in residential
buildings constructed before which year is presumed to be lead-based?
A. 1950
B. 1960
,C. 1970
D. 1978
Correct Answer: B
Rationale: Local Law 1 establishes a rebuttable presumption that paint in buildings built
before 1960 is lead-based. Distractor D (1978) is the federal EPA RRP cutoff for
requiring lead-safe work practices, not the NYC presumption threshold.
Question 3
A supervisor is assigned to repaint a two-bedroom unit in a pre-1960 NYCHA
development. A family with a 4-year-old child still occupies the unit. Under NYC Local
Law 1 and EPA RRP, what is the supervisor’s first required action before beginning
surface disturbance?
A. Begin painting immediately using fast-drying latex paint to minimize exposure time
B. Post warning signs, establish containment barriers, and ensure the child is not
present in the work area during disturbance
C. Paint only when the family is sleeping to minimize disruption
D. Skip sanding and surface preparation to reduce dust generation
Correct Answer: B
Rationale: Both Local Law 1 and EPA RRP mandate containment, signage, and ensuring
occupants—especially children under 6—are out of the work area during disturbance.
Distractor A ignores lead-safe requirements. Distractor C is unsafe. Distractor D violates
proper surface preparation standards and may not reduce lead hazard.
, Question 4
After sanding lead-painted surfaces in a unit, why must a supervisor ensure the crew
uses a HEPA vacuum rather than a standard shop vacuum for cleanup?
A. HEPA vacuums are quieter and disturb residents less
B. Standard shop vacuums exhaust fine lead dust particles back into the air, while HEPA
vacuums capture 99.97% of particles at 0.3 microns
C. HEPA vacuums are required only for final cleanup, not intermediate cleaning during
the job
D. Standard vacuums are more expensive to operate due to filter costs
Correct Answer: B
Rationale: HEPA filtration is required because it captures respirable lead dust; standard
vacuums redistribute fine particles. Distractor A is irrelevant to safety. Distractor C is
false—HEPA must be used throughout. Distractor D is factually incorrect.
Question 5
Under EPA RRP, after renovation work in a pre-1978 unit is complete and before
containment is removed, what must the certified renovator perform?
A. Immediate removal of all plastic sheeting to expedite completion
B. Thorough cleaning of the work area using HEPA vacuuming and wet wiping, followed
by a visual inspection for dust and debris
C. A final coat of sealant paint over all surfaces to encapsulate any lead dust
D. Air sampling by an independent industrial hygienist before any cleaning
