Taylor Property(4/2112021) Page 2 of 4 • Four(4)surface wipe samples were collected and analyzed for sixteen (16)"toxic"metals. Samples were sent to LA Testing in Huntington Beach, CA. Results were expressed in micrograms per 100 centimeters squared (pg/100 cm2). Results indicated ten (10)of the sixteen (16) metals assessed were found at measurable levels in at least one of the four sampled surfaces. Reportedly, concentrations provided in a table within the report were calculated using the OSHA Technical Manual for estimating exposure based on area samples. Levels were compared to OSHA (Occupational Safety and Health Administration)Permissible Exposure Limits (PELs)due to the absence of limits set for surface contamination. The calculation used in the table was intended to estimate the amount of contamination that could be transferred from a worker's hands and inadvertently ingested. Based on the calculation, one sample indicated one metal, cadmium, present at levels above worker safety standards. Additionally, the report noted that OSHA considers no level of lead safe and also compared results to "EPA limits"(no specific reference provided)and concluded that lead levels in two of the samples were above the EPA limit for lead dust on floors in child occupied homes. The report further stated the sample locations for the two lead samples are not specifically above the EPA limit as the samples were not taken from dust on a floor as the limit references. • Two (2)wipe samples were collected for combustion by-products (char, ash, soot)and sent to LA Testing in Huntington Beach, CA. Results were provided as visual percentages of char, ash and soot. One sample collected at a joist in the shop in a "stained" area indicated 9% of the dust was composed of combustion by-products. The sample collected at a joist in the attic in an area "not stained" indicated 22% of the dust was composed of combustion by-products. Based on sample results, Indy Safety concluded that it is also likely to be present on all surfaces in the shop and all surfaces in the house attic, including insulation. • On-site sensory observations (e.g., olfactory, visual)were not provided in the report. Recommendations for corrective actions were as follows: • Surfaces and contents that have been cleaned are not anticipated to present a health hazard. • HEPA vacuum and damp wipe all surfaces in the shop and any surfaces in the home that have not already been cleaned. • Remove insulation from the house attic and from the shop attic and clean all surfaces. Wipe all joist clean and seal with a clear sealant. • Remove any items that were determined "not salvageable" and that were not cleaned (i.e., leather sofa, pool table). On February 20, 2021. FACS performed a wildfire smoke impact assessment of the property on behalf of State Farm Insurance. The assessment included development of a site characterization and history, a sensory(visual and olfactory) investigation of the interior and exterior of the structure, and collection of surface samples from representative surfaces for particle characterization analysis. Findings, conclusions and recommendations can be found in FACS report dated March 23, 2021. A summary of findings and recommendations is as follows: • The exterior was covered with snow on the day of FACS' investigation, limiting accessibility. • Visible smoke related particulate was identified on curtains at the kitchen door(along with staining), attic space and on surfaces located directly adjacent to exterior entry points (< 5 ft) in the shed. • No observable smoke odors were identified on site. • Surface tape lift samples were collected from representative surfaces at the property and analyzed for particle characterization at SGS Forensics in Hayward, CA. Results indicated non- detect(ND)to Minor(3%) levels of combustion related particulate in the sampled dust adjacent to exterior entry points (< 5 ft). Results indicated non-detect to Trace (ND-<1%)levels of combustion related particulate in the sampled dust further away from exterior entry points (> 5 ft). www.forensicanatytical.com Right People.
