However, <br />discussions took place regarding the warehouse that included options for cleaning the contents within the <br />warehouse, potentially by creating containment chambers. At this time it appears that most contents have been <br />removed. <br />• Place all removed building materials in the sealed plastic bags prior to removal to the outdoors for disposal. <br />• These sealed plastic bags should be HEPA vacuumed and wiped down with an anti-microbial before they are <br />carried through non-contaminated areas. <br />• Contact ESG if hidden moisture damage or fungal contamination is observed or if you are unsure how any <br />hidden contamination should be addressed. <br />• Significantly moisture damaged or fungal damaged building materials should be removed. This includes any <br />porous or semi-porous (non-structurally significant) contents or building materials. It is possible that no <br />additional signs of suspect microbial growth are observed in the warehouse but a thorough inspection by the <br />remediation contractor will determine the condition. <br />• Structural materials that are significantly contaminated but cannot be removed must be thoroughly cleaned <br />with an anti-microbial chemical and then HEPA-vacuumed as indicated below. Structural materials with visible <br />fungal growth may be encapsulated with anti-microbial paint after the clearance test is complete. <br />PHASE II: CLEANING <br />Work Area (entire warehouse, warehouse contents, and connex): <br />• After all demolition has been completed, and all moisture issues are repaired, remaining building materials <br />should measure <20% moisture content (where applicable). Convert the negative air machines to air scrubber <br />function. <br />• The entire warehouse and connex should be cleaned. These areas can be cleaned by using traditional wiping and <br />HEPA vacuuming techniques or by using blast media such as dry ice. Currently, one option is to plan to convert <br />the warehouse into a conditioned space and leave the insulation at the ceiling and walls in place after cleaning. <br />The insulation has a plastic membrane facing the interior of the warehouse which should be able to be cleaned, <br />and damaged areas of this plastic membrane should be patched. <br />• Wipe down all remaining exposed surfaces with an EPA-registered anti-microbial. Using a ‘green’ product such <br />as Benefect is recommended. <br />• HEPA-vacuum all exposed surfaces. <br />• The IICRC recommends that the remediation contractor conduct pre-clearance air quality monitoring to identify <br />any remaining problem areas. A laser particle counter is ideal for this purpose. Checking air scrubber <br />performance, any air supplies, and breathing zone air is an important part of the monitoring process. <br />DocuSign Envelope ID: A9A4637A-BE59-4285-99BE-D253C29FA836
