D.1 Mold Assessment a) Conduct a comprehensive site assessment to determine the extent of mold contamination. b) Identify and document sources of moisture intrusion and recommend corrective actions. c) Develop a Mold Remediation Plan in accordance with industry standards such as the IICRC S520 Standard for Professional Mold Remediation. d) Obtain any necessary permits or approvals for remediation of work. e) Establish containment areas using negative air pressure and HEPA filtration to prevent cross-contamination. f) Post appropriate warning signage at work areas. D.2 Mold Removal and Remediation a) Remove all mold-contaminated materials in compliance with local, state, and federal regulations. b) Use HEPA vacuuming, damp wiping, and other industry-approved cleaning methods to remediate non-porous and semi-porous surfaces. c) Apply EPA-approved antimicrobial agents to treated surfaces to prevent regrowth. d) Dispose of all contaminated materials in accordance with applicable regulations. D.3 HVAC and Air Quality Remediation a) Inspect and clean the HVAC system, including ductwork, coils, and filters, to remove mold spores. b) Install new high-efficiency particulate air (HEPA) filters as needed. c) Conduct air quality testing pre- and post-remediation to verify effectiveness. D.4 Post-Remediation Verification and Final Clearance a) Perform final cleaning of all work areas, including the removal of containment barriers. b) Conduct post-remediation testing by an independent, third-party industrial hygienist. c) Provide a final report and clean letter with documentation of remediation activities, air quality test results, and recommendations for moisture control to prevent future mold growth. D.5 Safety and Compliance a) All work must comply with OSHA, EPA, and local environmental health regulations. b) Workers must wear appropriate personal protective equipment (PPE) throughout the project.
