Mold Remediation Certification Practice Exam

When particle board is affected by Category 3 water, which is water that is contaminated and poses a health risk, the best course of action is to remove and replace it. This type of water can come from sources such as sewage backups, flooding from contaminated sources, or other unsanitary water.

Particle board is highly absorbent and, once contaminated, can hold harmful pathogens and toxins that make it unsafe for use or occupation. Additionally, drying it with a fan may not be effective, as it can take a long time for the material to dry thoroughly, allowing mold and bacteria to proliferate in the meantime. Painting over it does not address the contamination problem and could even trap moisture, worsening the situation. Leaving the affected particle board in place poses significant health risks to occupants. Therefore, removing and replacing it is the only option that ensures a safe environment free of contaminants.
