MRS Mold Remediation Techniques and Procedures 3

Question 1

Which personal protective equipment (PPE) is the minimum required for remediating a small mold area (less than 10 sq ft)?

Accepted Answer

N95 respirator, safety glasses, and non-porous gloves

Answer

For small mold areas under 10 sq ft, minimum PPE includes an N95 respirator, eye protection, and non-porous gloves.

Question 2

What is encapsulation in the context of mold remediation, and when is it appropriately used?

Accepted Answer

Sealing porous materials that cannot be removed with a mold-resistant coating after cleaning

Answer

Encapsulation involves applying a specialized sealant over cleaned porous surfaces that cannot be removed, such as structural wood, to prevent spore release.

Question 3

During post-remediation verification (PRV), what is the clearance criterion that indicates successful remediation?

Accepted Answer

Indoor mold spore types and counts similar to or lower than outdoor levels

Answer

Successful remediation is confirmed when indoor airborne mold spore types and concentrations are comparable to or lower than outdoor baseline levels.

Question 4

What is the purpose of a pre-remediation assessment before starting mold remediation work?

Accepted Answer

To identify the extent of contamination, moisture source, and develop a remediation plan

Answer

A pre-remediation assessment identifies the scope of contamination, locates the moisture source, and allows development of a targeted remediation plan.

Question 5

When remediating mold on HVAC ductwork, what critical step must be taken first?

Accepted Answer

Shut down the HVAC system and seal all supply and return registers

Answer

The HVAC system must be shut down and all registers sealed before remediation to prevent spreading mold spores throughout the building via airflow.
