Update / Already Graded
Containment
Ans: To prevent cross-contamination- Containment is critical in
preventing the spread of mold spores to unaffected areas, thus
managing cross-contamination.
Pressure differential during remediation
Ans: Negative pressure of 0.05 inches of water column
Containment barrier material
Ans: 6-mil polyethylene sheeting
Airborne spores control method
Ans: High-efficiency particulate air (HEPA) filtering
Best practice for removing contaminated materials
Ans: Gently cutting and removing to minimize dust

Air monitoring timing
Ans: Throughout the project
Recommended respirator for mold removal
Ans: P100 respirator
Effective cleaning agents against mold
Ans: Household detergent, Vinegar, Sodium hypochlorite
(bleach). While household detergent and vinegar have some
efficacy, sodium hypochlorite is widely used due to its
effectiveness against mold, although it should be used properly.
Critical factor to prevent mold growth in water-damaged buildings
Ans: Humidity control
Strategy for managing mold on porous materials
Ans: Removal and disposal - Porous materials such as carpets
can trap mold spores and are often best removed and replace d.
