IICRC MRS Complete Test Guide for Mold Remediation
Newest 2026 Questions and Correct Detailed Answers
Already Graded A+
Visible mold growth, musty odors, and water stains on walls are indicators, while
high levels of UV light are not. - CORRECT ANSWER-Common indicators of
mold infestation
Negative pressure containment is often used in larger remediation projects. -
CORRECT ANSWER-Containment system used in larger remediation projects
A containment method used to manage areas during mold remediation. -
CORRECT ANSWER-Microbial barrier tents
A method of enclosing an area to prevent the spread of mold spores. - CORRECT
ANSWER-Soft-walled containment
A technique that effectively manages larger areas and keeps mold spores
contained during remediation. - CORRECT ANSWER-Negative pressure
containment
, A device that reduces humidity to inhibit mold growth by providing a less
favorable environment. - CORRECT ANSWER-Dehumidifier
A process that uses microbial action to break down complex mold spores when
physical removal is challenging. - CORRECT ANSWER-Bio-remediation
The primary purpose of using containment during mold remediation is to prevent
cross-contamination. - CORRECT ANSWER-Containment
A negative pressure of 0.05 inches of water column is typically required between
the containment area and the surrounding environment during remediation. -
CORRECT ANSWER-Pressure Differential
6-mil polyethylene sheeting is the most appropriate material for building a
containment barrier. - CORRECT ANSWER-Containment Barrier Material
High-efficiency particulate air (HEPA) filtering is typically employed to effectively
control airborne spores during remediation. - CORRECT ANSWER-Airborne
Spores Control Method
The best practice for removing contaminated materials such as drywall is gently
cutting and removing to minimize dust. - CORRECT ANSWER-Best Practice for
Removing Contaminated Materials
