 Answer Key Question 9: Answer: “B” FALSE Crawl spaces where relative humidity (RH) is high are common sites of hidden mold growth, particularly if the crawl space has a bare earth floor. The moisture that accumulates in a crawl space may also enter another part of the building and contribute to mold growth there. Moisture can pass from a crawl space into a building through cracks in walls, floors, and ceilings. www.epa.gov/mold/moldcourse/chapter2.html#2.6
