What should be done with water damaged cellulose ceiling tiles according to the EPA recommendations?

1. Reused after drying

2. Discarded

3. Cleaned and sealed

4. Painted over

The correct answer is: Discarded

According to the EPA recommendations, water-damaged cellulose ceiling tiles should be discarded. This is primarily because cellulose materials, such as those found in ceiling tiles, can absorb moisture, creating an ideal environment for mold growth. Once cellulose ceiling tiles have been water-damaged, they are difficult to adequately dry, and the potential for mold presence increases significantly, posing health risks to occupants and compromising indoor air quality. The recommendation to discard these tiles protects both the health of individuals in the space and helps prevent further contamination or damage. In contrast, attempting to reuse or clean these materials may lead to incomplete removal of mold or moisture, which can result in ongoing safety hazards. Additionally, painting over damaged tiles does not address the underlying problem and might mask mold growth, further complicating remediation efforts.
