Mold Remediation in Schools and Commercial Buildings 3 When mold growth occurs in buildings, adverse health problems may be reported by some building occupants, particularly those with allergies or respiratory problems. Remediators should avoid exposing themselves and others to mold-laden dusts as they conduct their cleanup activities. Caution should be used to prevent mold and mold spores from being dispersed throughout the air where they can be inhaled by building occupants. Prevention The key to mold control is moisture control. Solve moisture problems before they become mold problems! Mold Prevention Tips Fix leaky plumbing and leaks in the building envelope as soon as • possible. Watch for condensation and wet spots. Fix source(s) of moisture • problem(s) as soon as possible. Prevent moisture due to condensation by increasing surface temperature • or reducing the moisture level in air (humidity). To increase surface temperature, insulate or increase air circulation. To reduce the moisture level in air, repair leaks, increase ventilation (if outside air is cold and dry), or dehumidify (if outdoor air is warm and humid). Keep • heating, ventilation, and air conditioning (HVAC) drip pans clean, flowing properly, and unobstructed. Vent moisture-generating appliances, such as dryers, to the outside • where possible. Maintain low indoor humidity, below 60% relative humidity (RH), ideally • 30 – 50%, if possible. Perform regular building/HVAC inspections and maintenance as • scheduled. Clean and dry wet or damp spots within 48 hours. • Don't let foundations stay wet. Provide drainage and slope the ground • away from the foundation.
