1. Which primary goal defines mold remediation in a building?
A. Eliminating all mold spores permanently
B. Painting over contaminated materials
C. Reducing mold contamination to acceptable levels and preventing
recurrence
D. Increasing indoor humidity
The correct objective of remediation is to reduce contamination and
correct the moisture problem to prevent future growth, not to
eliminate all spores, which naturally exist in the environment.
2. What is the most important factor in mold growth?
A. Light exposure
B. Air pressure
C. Moisture
D. Paint type
Moisture control is the key to preventing and stopping mold growth,
as mold requires water to thrive.
3. Which document guides safe work practices during remediation?
A. Warranty contract
B. Remediation plan
C. Building blueprint
D. Insurance policy
, A remediation plan outlines containment, PPE, procedures, and scope
of work to ensure safe and effective cleanup.
4. What is the purpose of containment?
A. Increase airflow
B. Prevent spread of mold spores
C. Dry materials faster
D. Improve lighting
Containment limits the movement of spores to unaffected areas of
the building.
5. Which PPE is essential during mold remediation?
A. Sunglasses
B. Cotton gloves
C. Respirator with appropriate filtration
D. Ear plugs
Respirators protect workers from inhaling airborne spores and
contaminants.
6. Which respirator is commonly used for mold remediation?
A. Surgical mask
B. Dust cloth
C. N95 or higher-level respirator
D. Gas mask only
An N95 or higher respirator provides filtration suitable for mold
spore exposure.
7. What should be done before disturbing moldy materials?
A. Vacuum immediately
B. Establish containment and negative air pressure
C. Spray perfume
D. Paint over area
Proper preparation prevents cross-contamination during removal.
8. Negative air pressure is achieved using:
A. Fans blowing inward
B. Open windows
C. HEPA-filtered negative air machines
D. Dehumidifiers only
, Negative air machines with HEPA filters help prevent contaminated
air from escaping containment.
9. HEPA filters capture particles as small as:
A. 10 microns
B. 5 microns
C. 0.3 microns
D. 1 millimeter
HEPA filters are rated to capture 99.97% of particles at 0.3 microns.
10. Which material is typically removed when heavily mold-
contaminated?
A. Metal framing
B. Concrete slab
C. Porous drywall
D. Steel beams
Porous materials cannot be effectively cleaned when heavily
contaminated and must often be removed.
11. Which condition most often causes indoor mold growth?
A. Low temperature
B. Water leaks
C. Dry air
D. Insulation
Water intrusion from leaks is a primary cause of mold problems.
12. After removal, affected areas should be:
A. Ignored
B. Painted immediately
C. Cleaned and HEPA vacuumed
D. Covered with plastic
Proper cleaning ensures residual spores and debris are removed.
13. What is the first step in a remediation project?
A. Demolition
B. Assessment of moisture and contamination
C. Painting
D. Billing
Understanding the extent of contamination guides safe remediation
procedures.
