1. What should a supervisor do if a worker is found to have lead
contamination on their clothing?
A. Ignore it and continue work
B. Send the worker for a blood lead test
C. Have the worker change into clean clothes and decontaminate
D. Allow the worker to continue working
Answer: C) Have the worker change into clean clothes and
decontaminate
Rationale: The supervisor must ensure that workers decontaminate and
change clothing to prevent the spread of lead dust and reduce exposure
risks.
2. Which of the following is considered an effective lead abatement
method for windows?
A. Sanding the window frame
B. Replacing the window
C. Using a lead encapsulant
D. Painting over the lead paint without preparation
Answer: B) Replacing the window
,Rationale: Replacing windows that contain lead-based paint is often the
most effective abatement method, as it eliminates the risk of exposure
entirely.
3. How should respirators be selected for lead abatement work?
A. Based on the worker’s personal preference
B. Based on the lead exposure level and type of work
C. Any dust mask is sufficient
D. Only disposable face masks are acceptable
Answer: B) Based on the lead exposure level and type of work
Rationale: Respirators must be selected based on the type of work and
the potential lead exposure to ensure adequate protection.
4. What should be done if lead-based materials are found behind a
surface that was not initially identified as contaminated?
A. Ignore it if it is not visible
B. Immediately stop work and reassess the site
C. Continue work as planned
D. Seal the area and allow it to cure
Answer: B) Immediately stop work and reassess the site
Rationale: Any unexpected discovery of lead-based materials requires
reassessment of the work area to determine appropriate handling.
, 5. What is the maximum permissible level of lead in dust on floors,
according to the EPA?
A. 5 µg/ft²
B. 40 µg/ft²
C. 250 µg/ft²
D. 500 µg/ft²
Answer: B) 40 µg/ft²
Rationale: The EPA's guideline for permissible lead levels in dust on
floors is 40 µg/ft².
6. What is the minimum ventilation required for a lead abatement work
area?
A. No ventilation is needed
B. Ventilation that creates negative pressure to contain dust
C. Ventilation to maintain air circulation
D. Ventilation that reduces humidity levels
Answer: B) Ventilation that creates negative pressure to contain dust
Rationale: Negative pressure ventilation helps contain lead dust within
the work area, preventing it from spreading.
7. Which of the following is a key sign that lead-containing materials
may be deteriorating?
A. The material is shiny
contamination on their clothing?
A. Ignore it and continue work
B. Send the worker for a blood lead test
C. Have the worker change into clean clothes and decontaminate
D. Allow the worker to continue working
Answer: C) Have the worker change into clean clothes and
decontaminate
Rationale: The supervisor must ensure that workers decontaminate and
change clothing to prevent the spread of lead dust and reduce exposure
risks.
