1. 1An initial North Carolina supervisor applicant relies on prior lead work rather than other related experience. What minimum experience satisfies the supervisor qualification route?

   1. A. One year as a certified lead abatement worker
   2. B. Six months as a certified lead abatement worker
   3. C. Two years as a certified lead abatement worker
   4. D. Three years as a certified lead abatement worker

   Answer: A

   Explanation: Rule .0802(c)(2) requires "one year experience as a certified lead abatement worker." The worker-experience route therefore requires one year.

   Reference: SUBCHAPTER 19C � OCCUPATIONAL HEALTH — § 10A NCAC 41C .0802(c)(2)(A)

2. 2What site-specific tailoring does North Carolina require when a supervisor prepares an occupant protection plan for permitted abatement?

   1. A. It must be unique to each dwelling or child-occupied facility
   2. B. It may be reused for every project owned by one client
   3. C. It may cover every site operated by one firm
   4. D. It must be identical for every unit in the county

   Answer: A

   Explanation: The official guidance directs, "Write a unique OPP for each residential dwelling and/or child-occupied facility." A generic firm-wide plan does not meet that requirement.

   Reference: Lead-Based Paint Abatement Activities | Division of Public Health — § 1, Minimum Criteria for the Occupant Protection Plan, item 1

3. 3What authorization is generally required before conducting a lead abatement project covered by North Carolina law?

   1. A. A lead abatement permit
   2. B. A renovator-only certificate
   3. C. A training-course approval
   4. D. A laboratory recognition letter

   Answer: A

   Explanation: Rule .0808(a) states, "No person shall conduct abatement without an abatement permit issued by the Program." A covered project therefore requires the Program's permit.

   Reference: SUBCHAPTER 19C � OCCUPATIONAL HEALTH — § 10A NCAC 41C .0808(a)

4. 4Where must the written occupant protection plan be kept during a permitted North Carolina project?

   1. A. At the firm's registered office
   2. B. With the property owner's tax records
   3. C. At the training provider's office
   4. D. On the project site

   Answer: D

   Explanation: The official direction is, "Keep the written OPP on site for all permitted projects." Off-site storage alone does not satisfy this project-site requirement.

   Reference: Lead-Based Paint Abatement Activities | Division of Public Health — § 1, Minimum Criteria for the Occupant Protection Plan, item 1

5. 5Before laying plastic sheeting or another impermeable ground or floor covering, what must workers remove?

   1. A. All paint chips already present
   2. B. Only loose dust already present
   3. C. Only movable furnishings in the work area
   4. D. Only the top layer of exposed soil

   Answer: A

   Explanation: The work-practice guidance states, "All paint chips present on the ground or floor must be removed before plastic sheeting or other impermeable material is laid down." Removal prevents existing contamination from being hidden under containment.

   Reference: Nc Abatement Work Practices — § 1, Resident Protection and Worksite Preparation, item 2

6. 6What must happen to damaged substrates before preparing a site for encapsulation or enclosure?

   1. A. They must be covered with loose sheeting
   2. B. They must be left for post-clearance repair
   3. C. They must be marked only
   4. D. They must be repaired or replaced

   Answer: D

   Explanation: The guidance states, "All damaged substrates must be repaired or replaced before the site can be prepared for encapsulation and/or enclosure." Sound substrates are a precondition for those methods.

   Reference: Nc Abatement Work Practices — § 1, Resident Protection and Worksite Preparation, item 5

7. 7How long after final cleanup must a project wait before clearance dust sampling begins?

   1. A. At least one hour
   2. B. At least fifteen minutes
   3. C. At least four hours
   4. D. At least twenty-four hours

   Answer: A

   Explanation: The guidance directs, "Perform clearance dust sampling no sooner than one hour after completion of the final cleanup to permit airborne leaded dust to settle." One hour is the minimum wait.

   Reference: Lead-Based Paint Abatement Activities | Division of Public Health — § 1, Clearance, item 2

8. 8Which conduct can support suspension or revocation of an individual's North Carolina lead certification?

   1. A. Changing a mailing address after certification
   2. B. Declining work outside the certification scope
   3. C. Violating the lead program rules
   4. D. Using another permitted disposal facility

   Answer: C

   Explanation: Rule .0802(h) permits discipline for "any violation of G.S. 130A, Article 19A or these Rules" Compliance with the lead program rules is therefore a condition of continued certification.

   Reference: SUBCHAPTER 19C � OCCUPATIONAL HEALTH — § 10A NCAC 41C .0802(h)

9. 9A supervisor applicant has never held worker certification but has qualifying experience in a related field. How much related-field experience is required?

   1. A. One year
   2. B. Two years
   3. C. Three years
   4. D. Four years

   Answer: B

   Explanation: Rule .0802(c)(2) permits "at least two years of experience in a related field." Two years is the applicable alternative to one year as a certified worker.

   Reference: LEAD CERTIFICATION APPLICATION — § 10A NCAC 41C .0802(c)(2)

10. 10For a four-dwelling North Carolina abatement project, which certified discipline may prepare the required occupant protection plan?

    1. A. Only a certified risk assessor
    2. B. A certified lead supervisor
    3. C. Only the property owner
    4. D. A certified worker

    Answer: B

    Explanation: The guidance states, "If the project includes fewer than five residential dwellings, a certified lead supervisor can prepare the OPP." Four dwellings fall below the five-dwelling threshold.
