Answer Key

Question 1: Answer: “A” TRUE
A dry item before mold grows, if possible. In most cases, mold will not grow if wet or damp items are dried within 24‐48 hours. www.epa.gov/mold/moldcourse/chapter4.html#4.1

Question 2: Answer: “B” Cellulose or fiberglass insulation
Some water‐damaged items, including ceiling tiles, cellulose and fiberglass insulation, drywall and gypsum board, and books and papers, may have to be discarded. If valuable or important books, documents, or other items are moldy or water damaged, you may wish to consult a restoration, water damage, or remediation expert. www.epa.gov/mold/moldcourse/chapter4.html#4.1

Question 3: Answer: “A” TRUE
Before planning a remediation effort, the size and extent of the mold problem and any continuing moisture problems should be assessed. A remediation generally can be divided into small (less than 10 square feet of mold), medium (10‐ 100 square feet of mold), and large jobs (more than 100 square feet of mold). www.epa.gov/mold/moldcourse/chapter4.html#4.2

Question 4: Answer: “A” TRUE
Remediating mold and moisture problems may be complex, and it may increase workers' exposure to mold unless personal protective equipment (PPE) is used. www.epa.gov/mold/moldcourse/chapter4.html#4.2

Question 5: Answer: “E” N‐95 respirator, Gloves, and Goggles
Consider using PPE if disturbing mold during a building inspection, assessment, or walkthrough, for example. The minimum PPE is an N‐95 respirator (available at most hardware stores), gloves, and goggles. www.epa.gov/mold/moldcourse/chapter4.html#4.2

Question 6: Answer: “D” All of the above
The remediation plan should include: Whether containment will be required; what level of PPE will be used; how the water or moisture problem will be fixed so the mold problem does not recur; and, how the moldy building materials will be removed to avoid spreading mold. www.epa.gov/mold/moldcourse/chapter4.html#4.3

Question 8: Answer: “A” TRUE
If possible, remediation activities should be scheduled during off‐hours, when building occupants are less likely to be affected. www.epa.gov/mold/moldcourse/chapter4.html#4.4
