1. A Colorado lead abatement contractor is preparing to begin a
residential project involving deteriorated lead-based paint on
multiple interior surfaces. Before selecting work methods and
containment procedures, what is the most appropriate initial step?
A. Begin wet scraping immediately because all deteriorated paint is
presumed hazardous
B. Determine the presence and location of lead-based paint through
appropriate inspection or risk assessment information and evaluate the
scope of the planned disturbance
C. Remove all painted components regardless of condition to eliminate
future liability
D. Apply a new coat of paint over all surfaces before evaluating substrate
conditions
B. Determine the presence and location of lead-based paint through
appropriate inspection or risk assessment information and evaluate the
scope of the planned disturbance
,Rationale: Appropriate project planning begins with reliable information
concerning the presence, location, condition, and potential disturbance
of lead-based paint so that suitable work practices, worker protection,
containment, cleanup, and clearance procedures can be selected.
2. Which characteristic most clearly distinguishes lead abatement from
ordinary renovation or repainting work?
A. Abatement is intended to permanently eliminate or control identified
lead-based paint hazards using approved methods
B. Abatement always requires demolition of the entire building
C. Abatement can be performed only on exterior structures
D. Abatement consists solely of applying a new finish coat over existing
paint
A. Abatement is intended to permanently eliminate or control identified
lead-based paint hazards using approved methods
Rationale: Lead abatement is a specialized activity designed to
permanently address lead-based paint hazards, whereas ordinary
renovation or maintenance may disturb painted surfaces without having
permanent hazard elimination as its primary objective.
3. During project planning, why should the contractor establish the
boundaries of the work area and adjacent spaces before work
begins?
A. To determine which workers receive payroll records
B. To identify areas requiring protection and to reduce the migration of
,lead-contaminated dust beyond the work zone
C. To eliminate the need for cleaning after the project
D. To avoid documenting the location of contaminated materials
B. To identify areas requiring protection and to reduce the migration of
lead-contaminated dust beyond the work zone
Rationale: Clearly defining the work area allows the contractor to
establish containment, protect nearby surfaces and occupants, control
access, and prevent lead-contaminated dust and debris from spreading
into uncontaminated areas.
4. Which work practice is generally most effective for reducing
airborne lead dust when removing loose paint by hand?
A. Dry sanding the surface at high speed
B. Using compressed air to blow dust away from the worker
C. Using wet methods that suppress dust generation while performing the
removal activity
D. Sweeping the floor continuously during paint removal
C. Using wet methods that suppress dust generation while performing
the removal activity
Rationale: Wet methods reduce the amount of lead-containing dust
becoming airborne during surface disturbance and are therefore an
important exposure-control measure when compatible with the work
activity and substrate.
, 5. Why is open-flame burning an inappropriate method for removing
lead-based paint?
A. It makes paint too difficult to collect as waste
B. It can generate hazardous fumes and airborne lead contaminants
C. It prevents workers from wearing gloves
D. It eliminates the need for respiratory protection
B. It can generate hazardous fumes and airborne lead contaminants
Rationale: Heating lead-containing coatings excessively can create
dangerous fumes and airborne contaminants, increasing inhalation
exposure risks to workers and potentially contaminating surrounding
areas.
6. A contractor is establishing an interior containment area for
extensive lead abatement. What is the primary purpose of
containment barriers?
A. To improve the decorative appearance of the work area
B. To increase ventilation throughout the building without restriction
C. To isolate the work area and minimize the spread of contaminated dust
and debris
D. To eliminate the requirement for worker protective equipment
C. To isolate the work area and minimize the spread of contaminated
dust and debris
