Answer Key
Question 1: Answer: “A” TRUE
If there has been a leaking pipe in the basement, for example, items such as carpets, paneling, and drywall there should be checked for water damage or mold growth. It is important to dry items quickly to prevent mold growth; in most cases, items dried within 24‐48 hours will not become moldy. www.epa.gov/mold/moldcourse/chapter3.html#3.1
Question 2: Answer: “D” All of the Above
Possible locations of hidden mold also include damp areas behind walls and in crawlspaces, inside pipe chases and utility tunnels (areas in walls where water and other pipes are run), on acoustic liners in ventilation ducts, and on roof materials above ceiling tiles. www.epa.gov/mold/moldcourse/chapter3.html#3.1
Question 3: Answer: “A” TRUE
In some cases, water may enter the ventilation ducts from a leaky pipe. A contaminated ventilation system may spread mold spores throughout the building and should be considered a high priority for investigation and repair. www.epa.gov/mold/moldcourse/chapter3.html#3.1
Question 5: Answer: “B” FALSE
The use of personal protective equipment (PPE) should be considered during a mold investigation. The primary function of PPE is to avoid inhaling mold and mold spores and to avoid mold contact with the skin and eyes. Professional judgment should be used when selecting PPE. www.epa.gov/mold/moldcourse/chapter3.html#3.2
Question 6: Answer: “B” FALSE
Usually, if the mold can be seen, sampling is unnecessary. After finding mold, the goal is to clean it up and fix the underlying water problem. Unless the results would or could make a change in your plans, you don't need to sample. www.epa.gov/mold/moldcourse/chapter3.html#3.3
