IICRC MRS (Mold Remediation
Specialist) Exam Questions and
Correct Answers
The primary purpose of using containment during mold remediation is to
prevent cross-contamination.
Containment
A negative pressure of 0.05 inches of water column is typically required between
the containment area and the surrounding environment during remediation.
Pressure Differential
6-mil polyethylene sheeting is the most appropriate material for building a
containment barrier.
Containment Barrier Material
High-efficiency particulate air (HEPA) filtering is typically employed to effectively
control airborne spores during remediation.
, Airborne Spores Control Method
The best practice for removing contaminated materials such as drywall is gently
cutting and removing to minimize dust.
Best Practice for Removing Contaminated Materials
Air monitoring should be conducted during mold remediation.
Air Monitoring Timing
Ensures that containment is effective and that spore levels are controlled
throughout the remediation process.
Continuous air monitoring
Filters out 99.97% of airborne particles, making it suitable for mold remediation.
P100 respirator
Household detergent, vinegar, and sodium hypochlorite (bleach) are all effective,
with sodium hypochlorite being widely used due to its effectiveness.
