(8) Lead inspection and partial lead inspection.
(a) Who may conduct. Only a certified lead inspector or risk assessor associated with a certified lead company may perform an inspection involving target housing or a child-occupied facility. Under direct on-site supervision of a certified lead inspector or risk assessor, a certified lead hazard investigator or sampling technician may assist with an inspection, but may not use an XRF.
(b) Inspection protocol. In performing an inspection, the certified lead inspector or risk assessor shall comply with all requirements under pars. (c) to (f).
(c) Locations to test for lead-based paint. Select the following locations by using documented methodologies and test for the presence of lead-based paint:
1. In a dwelling or child-occupied facility, test each interior and exterior testing combination.
2. In a multi-family dwelling or child-occupied facility, also test each interior and exterior testing combination in every common area.
3. When a partial inspection is conducted to determine if lead-safe work practices are required in an area to be renovated, test each interior and exterior testing combination within that area in accordance with subd. 1. or 2. The inspection shall be based on a written contract under s. DHS 163.13 (5) that specifies the limits of the partial inspection. A partial inspection may not be conducted when a certificate of lead-free status is being sought.
Note: Refer to s. DHS 163.03 (29) for documented methodologies.
(d) Paint analysis. Conduct paint analysis by using one or both of the following methods:
1. Analyze paint to determine the presence of lead by using documented methodologies that incorporate adequate quality control procedures.
2. Have all collected paint chip samples analyzed by a recognized laboratory to determine if they contain detectable levels of lead that can be quantified numerically.
(e) XRF requirements. When using an XRF, a certified lead inspector or risk assessor shall be trained to operate the specific model of XRF being used and shall do all of the following:
1. Comply with radiation protection requirements under ch. DHS 157.
2. Replace the radiation source of the XRF according to recommendations from the manufacturer.
3. Warm up the XRF according to recommendations from the manufacturer or documented methodologies.
4. Conduct calibration checks according to recommendations from the manufacturer or documented methodologies.
5. Conduct substrate corrections when required.
6. If the XRF provides an inconclusive reading according to the performance characteristics sheet for the make and model of XRF used, assume the painted surface with the inconclusive reading contains lead-based paint unless sampling is required by contract. If a contract under s. DHS 163.13 (5) (d) specifies that sampling for the presence of lead-based paint should be conducted, conduct further testing or sampling and determine that lead-based paint is present if the laboratory results are more than 0.5% lead by weight or that lead-based paint is not present if the laboratory results are equal to or less than 0.5% lead by weight.
7. Except as specified under subd. 6., evaluate the results of each XRF reading as follows:
a. If the XRF reading exceeds 1 milligram per square centimeter, determine that lead-based paint is present.
b. If the XRF reading is less than or equal to 1 milligram per square centimeter, determine that lead-based paint is not present.
(f) Written report. Within 10 working days after an inspection or receipt of any required laboratory results, whichever is later, prepare a written inspection report for submission to the property owner or owners and to any other person who contracted for the inspection. The report shall include all of the following information:
1. Date of the inspection.
2. Address of building inspected.
3. Date of construction of the building.
4. Apartment numbers of units inspected, if applicable.
5. Name, address and telephone number of the current owner of each residential dwelling or child-occupied facility.
6. Name, address, telephone number, certification number and signature of each certified individual participating in the inspection.
7. Name, address, telephone number and certification number of the certified lead company conducting the inspection.
8. Each testing method and device and each sampling procedure used for paint analysis, including quality control data and, if used, the serial number of any XRF.
9. Specific locations of each painted component tested for the presence of lead-based paint.
10. The results of the inspection expressed in terms appropriate to the sampling method used.
11. A copy of any laboratory report of the analysis of collected paint chips.
(9) Risk assessment.
(a) Who may conduct. Only a certified lead hazard investigator or risk assessor associated with a certified lead company may perform a risk assessment involving target housing or a child-occupied facility. Under direct on-site supervision of a certified lead hazard investigator or risk assessor, a certified lead inspector or sampling technician may assist with a risk assessment.
(b) Risk assessment protocol. A certified lead hazard investigator or risk assessor shall perform a risk assessment according to all the requirements under pars. (c) to (k).
(c) Presence of lead-based paint. Treat all painted surfaces as lead-based paint. If a contract under s. DHS 163.13 (5) (d) specifies that sampling for the presence of lead-based paint should be conducted, select and test all of the following locations for the presence of lead-based paint by using documented methodologies:
1. Each testing combination with deteriorated paint.
2. Each interior windowsill.
3. Any other surface that is determined to be a potential lead-based paint hazard.
Note: Refer to s. DHS 163.03 (29) for documented methodologies.
(d) Background information. Collect background information on the physical characteristics of the residential dwelling or child-occupied facility and occupant use patterns that may cause lead-based paint exposure to a child under 6 years of age.
(e) Visual inspection. Conduct a visual inspection for risk assessment of the residential dwelling or child-occupied facility to locate the existence of deteriorated paint, assess the extent and causes of the deterioration and identify other potential lead-based paint hazards.
(f) Dust sampling.
1. ‘Dwellings.’ In dwellings, collect single-surface dust samples from the interior windowsill and floor in each of the following locations:
a. The floor where a child under 6 years of age is likely to come into contact with dust, including play areas within rooms, high-traffic walkways, room midpoints and areas underneath windows, in each room or area where a child under 6 years of age is likely to come into contact with dust.
b. The interior windowsill of the window that is most frequently operated or most frequently contacted by children under 6 years of age in each room or area where a child under 6 years of age is likely to come into contact with dust.
c. Common areas adjacent to the sampled residential dwelling.
d. Other common areas in the building where the hazard investigator or risk assessor determines that a child under 6 years of age is likely to come into contact with dust.
