LEAD SUPERVISOR EXAM COMPLETE QUESTIONS AND
ANSWERS | ALREADY PASSED | 2025 LATEST!!
Question 1
The OSHA Lead Construction Standard, 8 CCR 1532.1, applies to:
A. Only projects involving lead abatement.
B. Construction activities that involve removal of lead-based paint.
C. Construction activities that disturb paint with greater than 1.0 mg/cm²
lead.
D. Construction activities that disturb paint with any detectable
level of lead.
E. Only residential renovation projects.
Correct Answer: D) Construction activities that disturb paint with any
detectable level of lead.
Rationale: The OSHA standard applies broadly to any construction
work where lead is present, recognizing that disturbance of any
lead-containing material can create exposure.
Question 2
What are the minimum and maximum employee air monitoring flow rates
according to NIOSH Method 7082?
A. 0.5 to 2.0 LPM
B. 1.0 to 4.0 LPM
C. 2.0 to 5.0 LPM
D. 0.1 to 1.0 LPM
E. 4.0 to 8.0 LPM
,Correct Answer: B) 1.0 to 4.0 LPM
Rationale: NIOSH Method 7082 specifies these flow rates for personal
air sampling to measure airborne lead concentrations.
Question 3
Cal/OSHA's Respiratory Protection Standard (8 CCR 5144) requires fit testing
for:
A. All respirators.
B. Disposable dust masks only.
C. Loose-fitting powered air-purifying respirators (PAPRs).
D. All tight-fitting respirators.
E. Only supplied-air respirators.
Correct Answer: D) All tight-fitting respirators.
Rationale: Fit testing is crucial to ensure a proper seal between the
respirator facepiece and the wearer's face, preventing leaks and
ensuring protection.
Question 4
EPA is the federal government agency that controls the disposal of solid
waste. Which of the following California State agencies also controls the
disposal of solid waste (including hazardous waste)?
A. Cal/OSHA
B. CDPH (California Department of Public Health)
C. DFEH (Department of Fair Employment and Housing)
D. DTSC (Department of Toxic Substances Control)
,E. SWRCB (State Water Resources Control Board)
Correct Answer: D) DTSC (Department of Toxic Substances Control)
Rationale: DTSC is the primary California agency responsible for
regulating hazardous waste management.
Question 5
When performing abatement on the outside of a building, one layer of plastic
on the ground should extend how many feet beyond the perimeter of the
working surface?
A. 2 feet
B. 5 feet
C. 10 feet
D. 20 feet
E. 3 feet
Correct Answer: C) 10 feet
Rationale: This extended containment area helps prevent the spread
of lead-contaminated debris beyond the immediate work zone.
Question 6
The HUD Guidelines specifically prohibits which of the following activities
during lead-based paint abatement?
A. Wet scraping.
B. HEPA vacuuming.
C. Encapsulation.
D. Lead burning (open-flame burning).
, E. Paint removal.
Correct Answer: D) Lead burning (open-flame burning).
Rationale: Open-flame burning of lead-based paint creates highly
hazardous lead fumes and is strictly prohibited.
Question 7
According to the HUD Guidelines, heat guns should be used at temperatures
below:
A. 500°F
B. 800°F
C. 1000°F
D. 1100°F
E. 1500°F
Correct Answer: D) 1100°F
Rationale: Operating heat guns below 1100°F minimizes the
vaporization of lead, which produces highly toxic lead fumes.
Question 8
The chemical symbol for lead is:
A. Fe
B. Cu
C. Au
D. Ag
E) Pb
