Using a 'green' product such as Benefect is recommended. • HEPA-vacuum all exposed surfaces. • The IICRC recommends that the remediation contractor conduct pre-clearance air quality monitoring to identify any remaining problem areas. A laser particle counter is ideal for this purpose. Checking air scrubber performance, any air supplies and breathing zone air is an important part of the monitoring process. • It may be necessary to place plastic barriers at the cavities, especially if airborne particle counts continue to be an issue. Although these areas may appear to be clean,they may introduce some contaminants into the clean space and you may not be able to fully control the air quality without barriers. • Power off all air scrubbers in the building and fog it with an EPA-registered anti-microbial intended for bioaerosol application. • Power on the scrubbers after the manufacturer's recommended dwell time has elapsed. • Allow the air scrubbers to remain in operation for a minimum of 24 hours prior to collection of air samples for clearance testing (or until airborne particle load indicates that the home is ready for a clearance assessment). • Power on the HVAC system once the mechanical contractor has completed their evaluation and remediation cleaning of the air handler and duct system is complete. Handling of materials removed from the building or that will remain in the building: • Certain items removed from the building require special handling for removal of fungal spores. • Hard-surfaced non-porous materials such as solid wood furniture, metal contents, non-porous decorative items and glass may be HEPA-vacuumed, wiped down with an EPA-registered anti-microbial designed for wipe application, and HEPA-vacuumed one more time to remove inactive fungal spores. Test furniture in an inconspicuous area prior to wiping the entire piece with anti-microbial. General Recommendations: • Check for and document any areas of hidden damage and/or contamination during the remediation process. Contact ESG if you suspect contamination beyond that documented in this report. It is not unusual to find hidden areas of microbial growth or moisture damage when wet building materials are being removed. • The work areas should be left dry and visibly free from contamination and debris. • Do not apply an encapsulant or other substance that will prohibit a visual inspection of the building materials during the post-remediation verification (PRV) assessment. Encapsulants must be applied after an acceptable PRV assessment. • Seal the remediated areas to be clearance-tested after final cleaning to ensure entrance to the area is prohibited. Only the hygienist performing post-remedial testing is to enter the contained areas. Critical barriers are to remain in place until certification is issued by Environmental Solutions Group indicating that the building is safe for re-occupancy. • Contact Environmental Solutions Group at 336-373-1538 to schedule post-remediation verification testing of the remediated structure to certify that it is ready for continued restoration and safe for occupancy. Leave any HEPA filters running but turn off and remove non-HEPA containing dehumidifiers 48 hours prior to the PRV. Environmental Solutions Group • 1000 N.
