1. Under Colorado’s lead-based paint regulatory program, which entity
is responsible for administering certification requirements for lead-
based paint activities?
A. Colorado Department of Labor and Employment
B. Colorado Department of Public Health and Environment
C. Colorado Department of Transportation
D. Colorado Department of Local Affairs
Answer: B. Colorado Department of Public Health and Environment
Rationale: The Colorado Department of Public Health and Environment
(CDPHE) administers the state lead-based paint certification program
and oversees certification of individuals and firms performing regulated
lead-based paint activities.
2. Which type of property is generally within the scope of Colorado’s
lead-based paint activity requirements when the property was
constructed before 1978?
,A. Only commercial warehouses
B. Target housing and child-occupied facilities
C. Only industrial facilities
D. Only buildings constructed before 1950
Answer: B. Target housing and child-occupied facilities
Rationale: Colorado’s lead-based paint requirements apply particularly
to regulated activities involving target housing and child-occupied
facilities, especially those constructed before 1978.
3. What is the primary health concern associated with exposure to
deteriorated lead-based paint and contaminated dust?
A. Carbon monoxide poisoning
B. Lead poisoning
C. Silica poisoning
D. Oxygen deprivation
Answer: B. Lead poisoning
Rationale: Lead exposure can cause serious adverse health effects,
particularly in children, including neurological and developmental
impairment, making control of lead-containing paint and dust essential.
4. Before beginning regulated lead abatement work, what document
should establish the procedures for protecting occupants from lead
exposure?
A. Equipment rental agreement
B. Occupant protection plan
,C. Material delivery ticket
D. Contractor payment schedule
Answer: B. Occupant protection plan
Rationale: An occupant protection plan establishes the measures and
management procedures that will be used to protect building occupants
from lead hazards during abatement.
5. During lead abatement, which person should have responsibility for
directing and overseeing the abatement work?
A. Untrained laborer
B. Certified lead abatement supervisor
C. Property tenant
D. Material supplier
Answer: B. Certified lead abatement supervisor
Rationale: Lead abatement requires qualified and appropriately certified
personnel, and the supervisor is responsible for directing work and
ensuring that required work practices are followed.
6. Which activity is most likely to create a significant airborne lead
hazard when performed improperly on lead-containing paint?
A. Wet wiping
B. Dry sanding
C. HEPA vacuuming
D. Wet scraping
Answer: B. Dry sanding
, Rationale: Dry sanding can generate substantial quantities of fine lead-
containing dust and is therefore prohibited or severely restricted under
lead abatement work practices.
7. Why is HEPA filtration important during lead abatement?
A. It increases paint adhesion
B. It captures very small contaminated particles from air and surfaces
C. It neutralizes lead chemically
D. It prevents all moisture from entering a work area
Answer: B. It captures very small contaminated particles from air and
surfaces
Rationale: High-efficiency particulate air filtration is used with
appropriate equipment to capture fine lead-contaminated dust and
reduce the spread of hazardous particles.
8. Which practice provides the best method for minimizing lead dust
generation during paint removal?
A. Dry mechanical sanding
B. Wet methods combined with appropriate containment
C. Compressed-air blowing
D. Uncontrolled power grinding
Answer: B. Wet methods combined with appropriate containment
Rationale: Wet methods suppress dust generation, while containment
prevents contaminated material from spreading outside the regulated
work area.
