1. What is the primary purpose of a lead abatement supervisor on a
project site?
A. To manufacture lead-safe products
B. To oversee compliance with safety and regulatory requirements
during lead abatement
C. To sell construction materials
D. To perform laboratory testing of blood lead levels
Correct answer: B
Rationale: The lead abatement supervisor is responsible for
ensuring that all work follows applicable regulations, safety
procedures, and project specifications. They supervise workers
and ensure containment, proper removal methods, and
compliance with environmental and occupational standards.
,2. Which federal agency primarily regulates occupational exposure
to lead in construction?
A. FDA
B. EPA
C. OSHA
D. DOT
Correct answer: C
Rationale: OSHA (Occupational Safety and Health
Administration) sets and enforces permissible exposure limits
and workplace safety standards for lead exposure in construction
environments.
3. What is the OSHA permissible exposure limit (PEL) for lead in air
as an 8-hour time-weighted average?
A. 0.005 mg/m³
B. 0.05 mg/m³
C. 0.5 mg/m³
D. 5.0 mg/m³
Correct answer: B
Rationale: OSHA’s PEL for airborne lead exposure is 0.05
, milligrams per cubic meter of air averaged over an 8-hour work
shift.
4. What is the primary route of lead exposure in abatement work?
A. Skin absorption
B. Inhalation of dust
C. Eye contact
D. Ingestion of food additives
Correct answer: B
Rationale: The most significant route of occupational exposure to
lead during abatement is inhalation of airborne dust particles
containing lead.
5. Which type of respirator is typically required for high lead
exposure environments?
A. Surgical mask
B. Half-face air-purifying respirator
C. N95 dust mask only
D. No respiratory protection is needed
Correct answer: B
Rationale: A half-face or full-face air-purifying respirator with
, appropriate filters is commonly required when airborne lead
levels exceed permissible limits.
6. What is the purpose of negative air pressure in containment
areas?
A. To cool the work area
B. To prevent dust from escaping the containment zone
C. To increase oxygen levels
D. To dry paint faster
Correct answer: B
Rationale: Negative air pressure ensures that contaminated air
does not escape the work area, reducing the spread of lead dust
to clean zones.
7. Which material is commonly used to seal containment areas
during lead abatement?
A. Aluminum foil
B. Polyethylene sheeting
C. Cardboard
D. Cloth fabric
Correct answer: B
