What readings could be compared by a mold assessor to determine the potential for mold growth?

  1. Indoor temperature versus outside temperature

  2. Indoor humidity levels against outside measurements

  3. Air pressure levels inside and outside

  4. Dust levels compared to air quality standards

The correct answer is: Indoor humidity levels against outside measurements

Indoor humidity levels compared to outside measurements are crucial for assessing the potential for mold growth because mold thrives in environments with consistently high humidity. Typically, indoor humidity levels should remain below 60% to prevent mold proliferation. By comparing indoor humidity levels with those outside, a mold assessor can determine if the indoor environment is at an increased risk for mold growth due to excessive moisture. If indoor humidity is higher than the outdoor level, it may indicate poor ventilation, moisture intrusion, or other factors that could promote mold growth. Conversely, if indoor humidity is lower than outdoor levels, it may suggest proper environmental controls. This comparison is essential for developing effective remediation and prevention strategies. Thus, keeping tabs on humidity levels is a proactive approach to mold management.
