Questions & Study Guide
1. According to OSHA, what is the Action Level (AL) for airborne lead exposure, which
triggers requirements like medical surveillance and training?
a) 10 micrograms per cubic meter (μg/m³)
b) 30 micrograms per cubic meter (μg/m³)
c) 40 micrograms per cubic meter (μg/m³)
d) 50 micrograms per cubic meter (μg/m³)
Answer: b) 30 micrograms per cubic meter (μg/m³)
Explanation: The OSHA Action Level for lead is 30 μg/m³. Exposure at or above this level for
more than 30 days per year mandates specific protective measures, including initial medical
surveillance and biological monitoring.
2. Which of the following is a prohibited method for lead-based paint abatement due to the
high risk of creating inhalable lead fumes?
a) Using a chemical stripper without methylene chloride
b) Using a HEPA-filtered vacuum sander
c) Using a heat gun operating above 1100°F (593°C)
d) Wet scraping followed by HEPA vacuuming
Answer: c) Using a heat gun operating above 1100°F (593°C)
Explanation: Lead has a relatively low vaporization point. Heat guns operating above 1100°F
can vaporize lead, creating highly toxic and easily inhaled lead fumes, which is why this method
is restricted.
3. A Lead Abatement Supervisor's certification card expires in two years. To maintain
certification, what must they do?
a) Pass a state exam again
b) Complete a full initial training course
,c) Complete an 8-hour refresher course
d) Submit a new application and fee to the state
Answer: c) Complete an 8-hour refresher course
Explanation: OSHA and most state programs, including Wisconsin DHS 163, require certified
supervisors and workers to complete an 8-hour refresher training course every two years to
maintain their certification, ensuring they are up-to-date on regulations and safety practices.
4. Under the Resource Conservation and Recovery Act (RCRA), how is waste from a lead
abatement project on a single-family residence typically classified?
a) Universal Waste
b) Hazardous Waste, requiring a manifest
c) It is exempt under the Household Hazardous Waste exemption
d) Inert Construction and Demolition Debris
Answer: c) It is exempt under the Household Hazardous Waste exemption
Explanation: Waste generated from lead abatement in a residential setting occupied by a
homeowner or tenant is generally exempt from federal hazardous waste regulations under the
Household Hazardous Waste exemption. However, state and local regulations may vary.
5. Which of the following certified individuals is required to be on-site at all times during a
lead abatement project?
a) Lead Inspector
b) Project Designer
c) Lead Risk Assessor
d) Lead Abatement Supervisor
Answer: d) Lead Abatement Supervisor
Explanation: OSHA and state regulations require that a certified Lead Abatement Supervisor
must be on-site at all times during abatement activities to oversee work practices, safety
procedures, and compliance.
, 6. What is the correct HUD/EPA clearance standard for lead in dust on interior window
sills (window troughs) after an abatement?
a) 10 micrograms per square foot (μg/ft²)
b) 40 micrograms per square foot (μg/ft²)
c) 100 micrograms per square foot (μg/ft²)
d) 250 micrograms per square foot (μg/ft²)
Answer: c) 100 micrograms per square foot (μg/ft²)
Explanation: The current HUD/EPA clearance standards (as of 2019) are: Floors: 10 μg/ft²,
Interior Window Sills: 100 μg/ft², Window Troughs: 400 μg/ft². The provided document
contained outdated values which have been corrected here.
7. A qualitative fit test is being performed on a respirator. Which of the following describes
this process?
a) Using a probe inside the mask to numerically measure the amount of leakage.
b) Using an irritant like saccharin mist to see if the wearer can detect it.
c) Measuring the worker's lung capacity before and after donning the respirator.
d) Checking the manufacturer's assigned protection factor (APF) for the mask.
Answer: b) Using an irritant like saccharin mist to see if the wearer can detect it.
Explanation: A qualitative fit test relies on the wearer's subjective response (taste, smell,
irritation) to a test agent like saccharin, Bitrex, or irritant smoke to detect leakage. A quantitative
test uses mechanical equipment to measure leakage numerically.
8. Why is it critical to calibrate an air sampling pump before and after use?
a) To ensure the battery is fully charged for the entire monitoring period.
b) To precisely know the volume of air sampled for accurate exposure calculations.
c) To comply with EPA wastewater discharge regulations.
d) To activate the HEPA filter inside the sampling cassette.
Answer: b) To precisely know the volume of air sampled for accurate exposure calculations.
