Indoor Mold Sampling

John Huang, Ph.D., PE and John Poullain, PE

This two-hour online course provides guidelines for indoor mold sampling by surface and air methods. The topics covered include the sources of indoor mold problems and when sampling and testing a building for mold is necessary. The course considers methods to identify and locate mold sources, the effects on health, and ways to avoid mold growth. The course covers several links and references to informative sources covered in the text topics.

The most important ingredient for mold growth is moisture or water. Indoor mold needs a nutrient and organic material to grow. It will grow on wood, insulation and dirt when moisture is present. Since moisture is necessary, typical places to investigate in a building are leaky roofs and plumbing, leaks into the building from cracks, gutters or poorly designed exterior drainage. Because mold doesn’t need daylight, hidden mold is a serious source of contamination and locations conductive to growth must be considered. A building having visible mold, water damage, or moldy odors should be assessed without delay. Sources of water or leaking water should be stopped and repairs made to deter mold growth after a building is cleaned up. The goal of the course is to understand the importance of visual inspections and the options for mold sampling.

The student will become familiar with the causes of mold, its health risks, and suitable actions to take for indoor mold problems. Basic methods for improving indoor air quality and controlling sources of mold growth caused by water and moisture problems are discussed. The student will consider the methods of mold sampling and the importance of thorough visual inspections. Reference sources are provided for information pertaining to indoor mold problems and appropriate steps for reducing the exposure to occupants.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
