Mold Remediation Techniques and Procedures Flashcards

What is the purpose of installing an airlock (decontamination chamber) at the entrance to a remediation containment zone?

Answer: To provide a buffer zone where workers can remove PPE without cross-contaminating clean areas

An airlock provides a buffer zone where workers can remove and bag contaminated PPE before exiting, preventing cross-contamination of clean areas.

According to the EPA mold remediation guidelines, which professional should perform post-remediation air testing?

Answer: An independent industrial hygienist or third-party tester not affiliated with the remediation company

Post-remediation testing should be performed by an independent third party, such as an industrial hygienist, to ensure objectivity and avoid conflicts of interest.

What moisture reading in wood (measured with a pin-type moisture meter) generally indicates conditions conducive to mold growth?

Answer: Above 19% moisture content

Wood moisture content above 19% is generally considered conducive to mold growth, as mold can colonize wood at this moisture level over time.

When remediating mold in an occupied building, which document must be prepared and provided to occupants before work begins?

Answer: A written remediation plan or scope of work including relocation recommendations

A written remediation plan outlining work scope, containment measures, and recommendations for occupant relocation must be provided before remediation begins.

What is the correct procedure when a remediator encounters suspected asbestos-containing materials (ACM) in a building also affected by mold?

Answer: Stop all work, notify the client, and require asbestos testing before any disturbance

All work must stop upon discovery of suspected ACM; the client must be notified and asbestos testing performed before any disturbance to prevent asbestos fiber release.

Which fungal species is associated with 'sick building syndrome' and is commonly found on water-damaged gypsum drywall?

Answer: Stachybotrys chartarum

Stachybotrys chartarum (black mold) thrives on cellulose-rich, water-saturated materials like drywall and is associated with sick building syndrome due to mycotoxin production.

What is the recommended minimum time to allow a biocide/antimicrobial agent to remain on a surface (dwell time) before wiping or rinsing?

Answer: Follow the manufacturer's label instructions for specified dwell time

Dwell time must follow the manufacturer's label instructions, which are specific to each product's chemistry and the organisms it targets.
