Section 1: Federal & New Jersey Lead Regulations (NJ Lead
Law/EPA RRP/HUD) (Q1-15)
Q1. Under OSHA Lead Standard 29 CFR 1926.62, the Permissible Exposure Limit (PEL)
for lead is an 8-hour time-weighted average of:
A. 30 µg/m³
B. 50 µg/m³
C. 100 µg/m³
D. 200 µg/m³
B. 50 µg/m³ [CORRECT]
Rationale: OSHA sets the PEL at 50 µg/m³; 30 µg/m³ is the Action Level, 100 µg/m³ is
a common distractor, and 200 µg/m³ reflects outdated standards.
Correct Answer: B
Q2. Under EPA RRP Rule (40 CFR 745), lead-based paint (LBP) is legally defined as
paint containing:
A. ≥0.5 mg/cm² or ≥0.25% by weight
B. ≥1.0 mg/cm² or ≥0.5% by weight
C. ≥1.5 mg/cm² or ≥1.0% by weight
D. ≥2.0 mg/cm² or ≥1.5% by weight
B. ≥1.0 mg/cm² or ≥0.5% by weight [CORRECT]
,Rationale: EPA/HUD define LBP at ≥1.0 mg/cm² by XRF or ≥0.5% by weight via
laboratory analysis; distractors confuse lower thresholds sometimes cited by other
agencies.
Correct Answer: B
Q3. A renovation firm is hired to repair deteriorated windows in a 1974 rental
property. Under EPA RRP, the firm must:
A. Provide the EPA pamphlet only if a child under age 6 resides in the unit
B. Be an EPA-certified firm and assign a certified renovator because it is pre-1978
target housing
C. Exempt the job because the property is a rental, not owner-occupied
D. Only comply if the renovation disturbs more than 20 square feet of painted
surface
B. Be an EPA-certified firm and assign a certified renovator because it is pre-1978
target housing [CORRECT]
Rationale: EPA RRP applies to pre-1978 housing and child-occupied facilities
regardless of occupancy type; firm certification and a certified renovator are always
required for covered work.
Correct Answer: B
Q4. The OSHA Action Level (AL) for airborne lead under 29 CFR 1926.62 is:
A. 15 µg/m³ (8-hour TWA)
B. 30 µg/m³ (8-hour TWA)
C. 50 µg/m³ (8-hour TWA)
D. 100 µg/m³ (8-hour TWA)
B. 30 µg/m³ (8-hour TWA) [CORRECT]
,Rationale: The Action Level is 30 µg/m³, which triggers increased monitoring and
medical surveillance; 50 µg/m³ is the PEL and 100 µg/m³ is not an OSHA lead
threshold.
Correct Answer: B
Q5. During an exterior renovation of a 1960s home, a crew member proposes using
open flame burning to remove old paint. Under EPA RRP, this practice is:
A. Permitted if the crew uses respirators
B. Permitted only for areas less than 1 square foot
C. Prohibited under all circumstances
D. Permitted if a fire extinguisher is present
C. Prohibited under all circumstances [CORRECT]
Rationale: Open flame burning is an EPA RRP prohibited practice because it
volatilizes lead and creates toxic fumes; respirators or fire extinguishers do not make
this method allowable.
Correct Answer: C
Q6. Under HUD Lead Safe Housing Rule (24 CFR 35), the dust-lead clearance level for
interior floors is:
A. 10 µg/ft²
B. 40 µg/ft²
C. 100 µg/ft²
D. 250 µg/ft²
B. 40 µg/ft² [CORRECT]
Rationale: HUD and EPA RRP both set the floor dust clearance level at 40 µg/ft²; 250
µg/ft² applies to window sills and 10 µg/ft² is a common NJ inspection standard, not
HUD clearance.
, Correct Answer: B
Q7. A landlord in New Jersey is preparing to lease a pre-1978 residential unit. Under
NJ Lead Law (N.J.S.A. 24:14A-1 et seq.), the landlord must:
A. Provide the tenant with a DCA lead-safe certificate or lead-free certificate before
occupancy
B. Remove all lead-based paint regardless of condition
C. Test the tenant's child for lead before lease signing
D. Provide EPA pamphlet only if rent exceeds $1,500/month
A. Provide the tenant with a DCA lead-safe certificate or lead-free certificate before
occupancy [CORRECT]
Rationale: NJ law mandates landlords provide DCA lead-safe or lead-free certification
for pre-1978 rentals; paint removal is only required if hazards exist, and pamphlet
provision is not income-dependent.
Correct Answer: A
Q8. Which of the following tasks is NOT classified by OSHA 29 CFR 1926.62 as a
"trigger task" requiring immediate exposure monitoring?
A. Manual demolition of painted surfaces
B. Manual scraping of painted surfaces
C. Wet washing with HEPA vacuum attachment
D. Abrasive blasting
C. Wet washing with HEPA vacuum attachment [CORRECT]
Rationale: OSHA trigger tasks include manual demolition, scraping, power tool use,
abrasive blasting, and torch cutting; wet washing with HEPA control is an engineered
control method, not a trigger task.
Correct Answer: C
