Which sampling method is BEST suited for identifying the specific location of mold growth on a surface?
Answer: Surface tape-lift sampling
Tape-lift samples collect material directly from a surface, allowing the laboratory to identify mold species and density at a specific location.
A homeowner had a roof leak repaired six months ago. During inspection, a CMA finds no visible mold but elevated moisture readings in ceiling drywall. What does this finding suggest?
Answer: Residual moisture may still support mold growth, requiring further investigation
Drywall can retain moisture within its core even when surface-dry, and residual moisture above 15–17% can sustain or initiate mold growth.
When is it acceptable for a CMA to collect air samples using a spore trap during a mold inspection?
Answer: After ensuring HVAC systems have been running normally for at least 24 hours
Normal HVAC operation for 24 hours allows representative air mixing, ensuring that samples reflect typical indoor air quality conditions.
A CMA discovers water damage in a crawl space with visible mold covering more than 10 square feet of wood joists. According to IICRC S520 guidelines, this situation requires:
Answer: A licensed mold remediator to perform work under a separate remediation protocol
IICRC S520 classifies affected areas over 10 sq ft as Condition 3, requiring professional remediation separate from the assessment function.
What does a high spore count of Stachybotrys chartarum in an air sample during a mold inspection typically indicate?
Answer: Chronic, long-term water intrusion and wet cellulosic materials indoors
Stachybotrys chartarum requires persistently wet cellulosic materials (paper, wood) to amplify; its presence in air samples indicates chronic indoor moisture problems.
During an inspection, a CMA observes efflorescence on a basement wall. What does this finding indicate about potential mold risk?
Answer: Moisture is migrating through the masonry, creating conditions suitable for mold growth
Efflorescence is a mineral deposit left by evaporating water, indicating ongoing moisture migration that can support mold growth on adjacent organic materials.
A CMA is writing a mold assessment report. Which of the following is a REQUIRED element of the report under Florida administrative rules?
Answer: The scope of the mold assessment, findings, and recommendations for remediation if needed
Florida administrative code requires the assessment report to include the scope of work, findings of the inspection, and any recommendations for remediation.
