1. What is the primary objective of mold remediation?
A. Make the building smell better
B. Remove or clean mold-contaminated materials and correct the moisture
source
C. Increase indoor humidity
D. Seal every building surface
Answer: B. Remove or clean mold-contaminated materials and correct the
moisture source
Rationale: Effective remediation addresses both existing mold
contamination and the moisture conditions that allowed mold to grow.
, 2. Which condition is most important for mold growth?
A. Dry air
B. Adequate moisture
C. Bright lighting
D. High oxygen concentration only
Answer: B. Adequate moisture
Rationale: Mold requires moisture, along with an organic food source and
suitable environmental conditions, to grow.
3. What is the first priority when mold is discovered following a water
intrusion?
A. Paint the affected area
B. Apply fragrance
C. Identify and correct the moisture source
D. Install carpet over the area
Answer: C. Identify and correct the moisture source

5. What is the purpose of a moisture meter during a mold assessment?
A. Measure airborne mold spores directly
B. Determine the moisture condition of building materials
C. Identify mold species
D. Measure carbon monoxide
Answer: B. Determine the moisture condition of building materials

remediation?
A. Leaving containment doors open
B. Using negative air pressure where appropriate
C. Moving contaminated materials through occupied areas
D. Turning off all containment controls
, Answer: B. Using negative air pressure where appropriate
Rationale: Proper containment and pressure control help prevent
contaminated air from migrating into clean areas.
7. What is the purpose of containment?
A. Increase mold growth
B. Prevent the spread of contaminants to unaffected areas
C. Make demolition easier
D. Increase room temperature
Answer: B. Prevent the spread of contaminants to unaffected areas
Rationale: Containment separates the remediation work area from
surrounding clean spaces.
8. Which device is commonly used to create negative pressure inside
containment?
A. Dehumidifier only
B. Air scrubber or negative-air machine with appropriate filtration
C. Thermostat
D. Moisture meter
Answer: B. Air scrubber or negative-air machine with appropriate filtration
