1. 1An owner has hired an inspector to test specified painted surfaces in every unit of a small property. Which review of the completed inspection best verifies that the contracted field scope was delivered?

   1. A. Compare the contracted unit-and-surface list with the completed testing inventory.
   2. B. Compare each XRF calibration entry with the instrument's tolerance limits.
   3. C. Compare sample identifiers on the chain of custody with the lab report.
   4. D. Compare reported XRF classifications with the instrument's PCS ranges.

   Answer: A

   Explanation: HUD advises: "The owner should monitor the risk assessment or inspection to ensure that all dwelling units and surfaces to be tested are in fact examined." Comparing the agreed list with the completed inventory tests coverage directly. The other comparisons check real quality-control matters, but none establishes that every contracted unit and surface was examined.

2. 2A consultant is paid to investigate possible lead-based paint in an occupied California apartment building. Under Title 17, which classification best describes this service?

   1. A. A lead hazard evaluation
   2. B. A containment assessment
   3. C. An industrial hygiene audit
   4. D. An abatement activity

   Answer: A

   Explanation: Title 17 defines a lead hazard evaluation as an "on-site investigation, for compensation, of lead-based paint or lead hazards for public and residential buildings." The paid apartment investigation fits that definition.

   Reference: Title 17_CACodeofRegulations_Div1_Chapter8 — 17 CCR section 35038

3. 3Besides identifying hazards, what must a California risk assessment suggest?

   1. A. Appropriate control actions
   2. B. A surface-by-surface paint inventory
   3. C. A clearance determination
   4. D. An abatement project design

   Answer: A

   Explanation: The state definition includes suggesting appropriate ways to control identified lead hazards. Official text: "Risk assessments determine the presence or absence"

   Reference: Chapter 5: Risk Assessment — 17 CCR section 35047

4. 4An XRF result for a painted surface is exactly 1.0 mg/cm². How does California classify the coating?

   1. A. Below the areal paint threshold
   2. B. A coating meeting the areal lead criterion
   3. C. Lead-contaminated dust
   4. D. Presumed lead-free paint

   Answer: B

   Explanation: Lead-based paint includes coating with lead "equal to, or in excess of" 1.0 mg/cm². Equality meets the California threshold.

   Reference: Title 17_CACodeofRegulations_Div1_Chapter8 — 17 CCR section 35033(a)

5. 5Which HUD Guidelines chapter supplies the California clearance-inspection procedures?

   1. A. Chapter 5
   2. B. Chapter 7
   3. C. Chapter 15
   4. D. Chapter 18

   Answer: C

   Explanation: California incorporates sections II through VI of HUD Guidelines Chapter 15 for clearance inspections. Official text: "In accordance with procedures such as described in Chapter 15: Clearance, sections II-VI"

   Reference: Title 17_CACodeofRegulations_Div1_Chapter8 — 17 CCR section 36000(a)(2)

6. 6Laboratory analysis reports paint at exactly 0.5 percent lead by weight. What is the California classification?

   1. A. A coating meeting the weight-based lead criterion
   2. B. Lead-contaminated soil
   3. C. Below the regulatory threshold
   4. D. A negative screen only

   Answer: A

   Explanation: The weight criterion includes paint containing "half of one percent (0.5%) by weight" or more.

   Reference: Title 17_CACodeofRegulations_Div1_Chapter8 — 17 CCR section 35033(b)

7. 7A risk assessor is choosing whether to recommend interim lead controls at a property with deteriorated lead paint and contaminated household dust. Which additional property condition supports that choice under HUD Chapter 11?

   1. A. Dry, sound substrates with no separate mandate for abatement.
   2. B. Wet, sound substrates with no separate mandate for abatement.
   3. C. Dry, unsound substrates with no separate mandate for abatement.
   4. D. Dry, sound substrates where a rule separately requires abatement.

   Answer: A

   Explanation: HUD says: "It is easiest and most appropriate to use interim controls when substrates are structurally sound and lead exposure comes primarily from deteriorating paint and excessive levels of lead in household dust and/or soil." It also explains that moisture or unsound structure limits effectiveness, and a binding abatement requirement precludes interim controls. Only A satisfies the condition in the question.

   Reference: HUD Guidelines, Chapter 11: Interim Controls — Chapter 11, section I.A, When Interim Controls Are Appropriate

8. 8A preschool child plays daily on a floor with lead-contaminated surface dust. According to HUD, which route is the most common cause of childhood lead poisoning in housing?

   1. A. Breathing lead dust resuspended from the floor surface.
   2. B. Swallowing floor dust transferred from the child's hands.
   3. C. Swallowing lead paint chips detached from nearby trim.
   4. D. Drinking lead-contaminated water from the kitchen tap.

   Answer: B

   Explanation: HUD identifies the common cause as "the ingestion – through hand-to-mouth transmission – of lead-contaminated surface dust". Each listed route can expose a child, but the cited housing pathway emphasizes floor dust transferred to the mouth by hands.

   Reference: HUD Guidelines, Chapter 1: Introduction — Chapter 1, Lead in Surface Dust

9. 9A contractor wants a test performed only to determine whether a containment system is adequate. How does California Title 17 classify that test for lead hazard evaluation purposes?

   1. A. It is always a risk assessment
   2. B. Outside the lead hazard evaluation definition
   3. C. It is a clearance inspection
   4. D. It is a lead inspection

   Answer: B

   Explanation: The definition of lead hazard evaluation expressly excludes "activities intended to determine adequacy of containment." The requested test therefore is not a lead hazard evaluation under this definition.

   Reference: Title 17_CACodeofRegulations_Div1_Chapter8 — 17 CCR section 35038(a)

10. 10When is a lead-hazard screen most appropriate for a dwelling?

    1. A. Generally good paint condition with a low probability of hazards
    2. B. Generally good paint condition with a high probability of hazards
    3. C. Widespread poor paint condition with a low probability of hazards
    4. D. Widespread poor paint condition with a high probability of hazards

    Answer: A

    Explanation: HUD describes the screen as a limited evaluation for dwellings in relatively good condition where the probability of lead hazards is low. Official text: "more limited sampling"

    Reference: Chapter 5: Risk Assessment — Chapter 5, section II.A, Lead Hazard Screen
