DocuSign Envelope ID:6A1278D6-4287-4002-98A9-C69C8C1D313E Indoor Environmental Air Quality Assessment o All contents removed from contaminated areas should be cleaned and tested before being moved to a non-contaminated space. Specialized items such as electronics should be cleaned by a remediator that specializes in cleaning these types of items.Not all remediation contractors have the ability or technology to clean these types of items. It is recommended that the remediator provide references to the facility manager before the contract is awarded. o Any paper content items such as files should be removed from the building. These items should be cleaned and handled in accordance with the IICRC S520. These items should not be taken to a non-contaminated building or area. In some cases,files can be copied or scanned electronically. It is recommended that these items be handled by a certified remediation contractor who has experience with this process. o Set up a zip-door at the main entry if feasible. The remediation team's access to the area typically includes decontamination and egress chambers so that the indoor air quality professional has a clean area to dress and access the building at the clearance assessment. Consult with ESG as to how to configure the containment if you are unsure. o Position sufficient air scrubbers throughout the remediation zones to remove a minimum of four air volumes per hour. The number of needed air scrubbers may vary based on the remediator's recommendations and the PRV testing strategy. Place equipment where it can move the most air and reposition as necessary. Air scrubbing equipment needs to remain in operation until the PRV assessment is complete and/or permission is granted by ESG to remove equipment.Note: the amount of air scrubbing equipment may be adjusted up or down based on airborne particle mass readings obtained during the remediation and upon ESG's approval. o Use fans, air guns or leaf blowers once every 24 hours to stir up settled dust in the corners and near the floors,walls, and ceilings of the remediated portions of the building (note: this may require the owner to remove some items). Direct dust towards the air scrubbers to be filtered out of the air. HEPA pre-filters inside the air scrubbers should be changed or cleaned daily or per the manufacturer's recommendations. o Run drying equipment as needed to bring RH below 50% and wood moisture content to 16%or lower. Air movers and dehumidifiers may be required to effectively remove the moisture from the air and building materials. PHASE I: DEMOLITION • NOTE: Any moisture issues identified in this report or uncovered during the remediation must be confirmed as having been repaired prior to the replacement of building materials. • As mentioned above, establish negative pressure of the work zones prior to beginning work and position air scrubbers where they can move the most air. • Remove any items possible from the building to a location off-site. • Place all removed building materials in the sealed plastic bags prior to removal to the outdoors for disposal. • These sealed plastic bags should be HEPA vacuumed and wiped down with an anti-microbial before they are carried through non-contaminated areas. • Contact ESG if hidden moisture damage or fungal contamination is observed or if you are unsure how any hidden contamination should be addressed. • Significantly moisture damaged or fungal damaged building materials should be removed. This is especially important.
