MOLD REMEDIATION EXAM UPDATED
QUESTIONS AND CORRECT ANSWERS.
Proper remediation document involves documenting project conditions: - ANS Before, during

Correct order?
1. Ensure safety/health
2. Document conditions/processes
3. Control the contaminant
4. Remove the contamination
5. Correct the moisture problem - ANS CORRECT
Occupant exposure is controlled through: - ANS Containment that prevents occupants from
entering contaminated areas.
TRUE OR FALSE
Spores aerosolization is prevented through containment, proper engineering controls and work
practices. - ANS TRUE
TRUE OR FALSE

completed and materials are dried. - ANS TRUE
TRUE OR FALSE
