When remediating mold on structural wood framing, which technique is considered more effective than HEPA vacuuming alone for surface decontamination?
Answer: Dry ice blasting or soda blasting to physically abrade and remove mold from wood grain
Dry ice blasting and soda blasting are approved mechanical methods that physically remove mold from wood grain surfaces without adding moisture, making them superior to bleach treatment on porous wood.
How should mold-contaminated building materials be packaged for disposal during remediation?
Answer: Double-bagged in 6-mil poly bags, sealed, and wiped down before leaving the work area
Mold-contaminated waste must be double-bagged in heavy-duty 6-mil polyethylene bags and sealed before being transported through or out of the building to prevent spore release.
What is 'encapsulation' in the context of mold remediation and when is it appropriately used?
Answer: Applying a specialized coating to lock in residual mold after surface cleaning when removal is not feasible for structural reasons
Encapsulation is a secondary treatment applied after physical cleaning to seal residual staining on structural materials that cannot be safely removed, and is not a substitute for physical mold removal.
Which action must be taken with the HVAC system during active mold remediation in a building?
Answer: The HVAC system should be shut down or isolated to prevent spore distribution throughout the building
The HVAC system must be shut down or isolated from the work area during remediation to prevent contaminated air from being distributed to unaffected areas of the building.
What is the first step a mold inspector should take when writing a remediation protocol for a client?
Answer: Identify and document the moisture source that caused the mold growth to ensure it is addressed
Identifying and requiring correction of the moisture source is the foundational first step — without fixing the water intrusion or condensation problem, remediation will fail and mold will return.
Under what circumstances can a single-phase post-remediation verification be considered insufficient?
Answer: When the moisture source has not been corrected prior to testing, as results may not reflect long-term remediation success
If the underlying moisture problem has not been corrected before PRV, mold may recur after passing clearance; a follow-up inspection after moisture correction is warranted in such cases.
