Therefore,rigorous professional remedial actions per the IICRC S520 Standard to remove the microbial hazards,protect the occupants and a high level of care to protect remediation personnel are very important. o The protocols indicated below are designed to address the fungal hazard issues indicated above and the findings of our investigation. The remediation contractor is not expected to remove all fungal spores from the building and contents; however,remediation is performed to minimize risk to occupants and building materials that can be compromised by fungal activity by restoring the building to normal fungal ecology as defined by the IICRC. The protocols are established in accordance with the policies established by document S520 published by the IICRC. The ANSI/S520 currently sets the standard for mold remediation. • To return the building to a normal fungal ecology and normal moisture levels,the entire building and its contents should be remediated by a certified remediation contractor using a remedial process aligning with IICRC S520. The building materials, contents and HVAC system with visible mold growth and/or wetness should be classified as Condition 3. The other building materials, contents, and parts of the HVAC system of the building should be classified as Condition 2. The certified remediation contractor should be engaged to oversee and complete all repairs and remediation of the building and its contents. See"Protocol References"below for more information and recommendations regarding the Condition 2 and 3 areas. The remediation contractor may have to subcontract certain services during the process,please reference the following recommendations: o Step 1: Repair sources of moisture and perform intrusive investigation as needed: ■ All active water-related issues should be discovered and repaired before or in conjunction with the beginning of remediation cleaning. In general,this could include but may not be limited to HVAC issues, foundation leaks,veneer leaks and any related plumbing leaks. • The professional(s) engaged to find and repair any active water issues should have qualifications relevant to the inspection that they are performing. This may include qualified professionals such as a licensed general contractor, a licensed plumber, and a NADCA certified HVAC professional. ■ The remediation contractor may need to perform exploratory demo and/or non- invasive techniques to discover all sources. When the source is discovered, all wet and/or rotted building materials should be removed, dried and/or cleaned before any final repairs are made and before, or in conjunction with,the remediation cleaning process. o Step 2: Demolition ■ Significantly moisture damaged or fungal damaged(Condition 3)porous building materials and/or contents should be discarded. Condition 3 semi-porous building materials can typically be restored(see Step 3), and Condition 3 semi-porous contents are often unrestorable due to staining, discoloration and decay caused by mold enzymes and therefore will likely need to be discarded. • Upon removal of Condition 3 building materials,the adjacent components should be inspected for additional signs of moisture damage and microbial growth which may require additional removal and/or cleaning of building Environmental Solutions Group • 7 Maple Leaf Drive,Ste 104, Greensboro, NC 27410 • 336-373-1538 4 www.Go-ESG.com
