The primary purpose of using containment during mold remediation is
to prevent cross-contamination.
Ans: Containment
A negative pressure of 0.05 inches of water column is typically required
between the containment area and the surrounding environment
during remediation.
Ans: Pressure Differential

The best practice for removing contaminated materials such as drywall
is gently cutting and removing to minimize dust.
Ans: Best Practice for Removing Contaminated Materials
Air monitoring should be conducted during mold remediation.
Ans: Air Monitoring Timing
Ensures that containment is effective and that spore levels are
controlled throughout the remediation process.
Ans: Continuous air monitoring
Filters out 99.97% of airborne particles, making it suitable for mold
remediation.
Ans: P100 respirator
Household detergent, vinegar, and sodium hypochlorite (bleach) are all
effective, with sodium hypochlorite being widely used due to its
effectiveness.
Ans: Effective cleaning agents against mold
