What happens when the relative humidity exceeds 60%?

• A. Mold becomes dormant
• B. Conditions become favorable for mold growth
• C. Air quality improves
• D. All contaminants are neutralized

Answer: (B)

When relative humidity exceeds 60%, the environmental conditions become favorable for mold growth. Mold spores require moisture to germinate and thrive, and high levels of humidity provide that necessary moisture. At this range, the moisture in the air can lead to condensation on surfaces, which contributes to dampness. This damp environment not only allows spores to grow but can also encourage the proliferation of existing mold colonies. Understanding how humidity levels relate to mold growth is crucial for mold prevention and remediation strategies. Maintaining indoor relative humidity below 60% is often recommended to inhibit mold growth and maintain a healthy indoor environment.
