IICRC (MOLD REMEDIATION SPECIALIST) EXAM
REVIEW WITH 250 REAL EXAM QUESTIONS AND
CORRECT VERIFIED ANSWERS/ GRADED A+
A containment method used to manage areas during mold remediation. -
ANSWER - Microbial barrier tents
A method of enclosing an area to prevent the spread of mold spores. -
ANSWER - Soft-walled containment
A technique that effectively manages larger areas and keeps mold spores
contained during remediation. - ANSWER - Negative pressure
containment
A device that reduces humidity to inhibit mold growth by providing a
less favorable environment. - ANSWER - Dehumidifier
A process that uses microbial action to break down complex mold spores
when physical removal is challenging. - ANSWER - Bio-remediation
A device designed to capture and filter airborne mold spores to improve
air quality. - ANSWER - HEPA air scrubber
pg. 1
,A type of pollution that disrupts the acoustic environment. - ANSWER -
Noise pollution
The significant financial expense associated with a process or product. -
ANSWER - High cost
A limitation of standard vacuums that prevents them from capturing fine
mold spores. - ANSWER - Inability to filter fine particles
Gear worn to minimize exposure to hazards, which should be donned
before entering mold-affected areas. - ANSWER - Personal protective
equipment (PPE)
A technique that detects hidden moisture accumulation by identifying
temperature differences. - ANSWER - Thermal imaging in mold
assessments
The process of confirming that mold spores are at acceptable levels post-
remediation. - ANSWER - Remediation verification
The action of cutting open the wall to assess the extent of the mold
problem. - ANSWER - Finding mold behind walls
Purpose of negative air pressure differentials - ANSWER - To enhance
airflow and prevent cross-contamination.
pg. 2
,Purpose of an air scrubber - ANSWER - To capture and remove mold
spores from the air.
Key component of mold remediation protocol - ANSWER - Following
industry guidelines and standards.
Function of a HEPA air scrubber - ANSWER - To capture and filter
airborne mold spores - HEPA air scrubbers are specifically designed to
capture and filter airborne particulates, including mold spores, to
improve air quality.
Major drawback of using bleach for mold remediation - ANSWER - It
can evaporate quickly - Bleach can evaporate quickly, limiting its
effectiveness on porous surfaces and allowing mold to return if not
adequately addressed.
Limitation of using a standard vacuum for mold cleanup - ANSWER -
Inability to filter fine particles - A standard vacuum does not have the
proper filtration system to capture fine mold spores, leading to potential
cross-contamination.
Practice to avoid during mold remediation - ANSWER - Breaking up
drywall without wetting it first - Breaking up drywall without wetting it
releases mold spores into the air, which should be avoided to minimize
airborne contamination.
pg. 3
, When to don personal protective equipment (PPE) - ANSWER - Before
entering any mold-affected area - PPE should be donned before entering
any mold-affected area to protect workers from exposure to harmful
spores.
Important factor in planning mold remediation in a hospital - ANSWER
- Potential patient exposure - Patient exposure is a critical concern, and
planning must incorporate risk management strategies to protect
vulnerable individuals.
Benefit of employing thermal imaging during mold assessments -
ANSWER - It detects hidden moisture accumulation - Thermal imaging
can identify temperature differences that indicate hidden moisture
accumulation conducive to mold growth.
Primary risk associated with inadequate training in mold remediation -
ANSWER - Inadequate training can lead to improper handling of mold,
increasing health risks and remediation failures.
Type of testing conducted after mold remediation - ANSWER - Both air
and surface sampling provide a comprehensive assessment of mold
presence post-remediation.
Essential practice for effective mold remediation - ANSWER - Sealing
off the work area is crucial to prevent the spread of mold spores during
remediation.
