SECTION 1: LEAD HEALTH EFFECTS & REGULATIONS (EPA/HUD/OSHA) Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 3-year-old in a 1974 apartment has a blood lead level of 8 µg/dL. The pediatrician
notes peeling paint on window sills and requests a dust evaluation. Under EPA's current
dust lead hazard standard, which floor dust level triggers a hazard determination in the
child's bedroom?
A. 10 µg/ft² ✓ CORRECT
B. 20 µg/ft²
C. 40 µg/ft²
D. 100 µg/ft²
Correct Answer: A
,Rationale: EPA's dust lead hazard standard for residential floors is 10 micrograms per
square foot, so any reading at or above that threshold triggers a hazard determination. A
level of 20 µg/ft² also exceeds the standard but the question asks for the threshold
value itself, not merely an elevated result. In clinical practice, even levels near 10
warrant response actions in target housing with young children.
Question 2 of 50
During air monitoring in a 1920s home being abated, an industrial hygienist calculates
an 8-hour TWA of 35 µg/m³ for a worker scraping interior walls. Under OSHA's lead in
construction standard, what does this reading trigger?
A. Immediate cessation of work
B. Medical surveillance and employee notification ✓ CORRECT
C. Mandatory respirator use only
D. A written hazard communication plan
Correct Answer: B
Rationale: OSHA's action level for lead in construction is 30 µg/m³; exceeding it triggers
medical surveillance and notification requirements for affected employees. The PEL is
50 µg/m³, so work does not cease at 35, but the employer must initiate medical
monitoring regardless of respirator use.
Question 3 of 50
A risk assessor inspects a 1976 duplex where two children under age 6 reside. The
owner wants to know whether HUD's Lead Safe Housing Rule applies to his property.
Which criterion determines that this dwelling is "target housing"?
A. The presence of any lead-based paint
B. A child with an elevated blood lead level
C. Residential construction completed before January 1, 1978 ✓ CORRECT
D. Receipt of federal housing rehabilitation assistance
, Correct Answer: C
Rationale: HUD defines target housing as residential housing constructed before 1978,
excluding certain 0-bedroom units and housing for the elderly or disabled with no
children under 6 present. The presence of lead paint or an elevated BLL does not define
target housing status; the construction date is the controlling factor.
Question 4 of 50
A 42-year-old lead abatement worker reports to the site clinic with abdominal pain,
irritability, and a metallic taste. His blood lead level comes back at 62 µg/dL. Under
OSHA regulations, what action is required?
A. Transfer to a different job site with lower exposure
B. Provide a half-mask respirator and continue work
C. Increase air monitoring frequency to daily
D. Immediate medical removal from all lead exposure ✓ CORRECT
Correct Answer: D
Rationale: OSHA mandates immediate medical removal when a worker's blood lead
level reaches or exceeds 50 µg/dL in construction. Continuing work with a respirator or
transferring to another site does not satisfy the medical removal requirement; the
worker must be removed from all lead exposure until levels decline.
Question 5 of 50
A painting contractor is hired to replace 20 windows in a 1972 single-family home where
a toddler lives. The contractor has never taken EPA RRP training. What is the
contractor's legal obligation before beginning work?
A. Obtain EPA firm certification and assign a certified renovator ✓ CORRECT
B. Test all surfaces for lead using an XRF analyzer
C. Notify the state health department 30 days in advance
D. Post a $10,000 performance bond for lead safety
