MOLD REMEDIATION CERTIFICATION
COURSE EXAM UPDATED QUESTIONS
AND CORRECT ANSWERS.
Fungal Ecology:
Condition 1 - ANS Normal fungal ecology:
- may have traces of fungal or mold growth.
- an indoor environment that may have settled spores, fungal fragments or traces of actual
growth whose identity, location, and and quantity are reflective of a normal fungal ecology for
a similar environment.
Condition 2 - ANS Settled spores:
- the fungal ecology shows settled spores with trace growth.
- an indoor environment which is primarily contaminated with settled spores that were
dispersed directly or indirectly from a condition 3 area.
- may have traces of actual growth
Condition 3 - ANS Actual growth:
- the fungal ecology shows traces of actual growth
- there is growing mold (visible or hidden)
- usually visible
