PDC 412
Mold Recognition: Effective Sampling Strategies and Results Interpretation

intermediate | 1.34 CM Points/ 8 Contact Hours/ 1.0 CEU/COC Point | Sunday | 8:00 a.m. - 5:00 p.m. | Limit: 50

Biological Monitoring, Mold

The PDC will enable participants to recognize indoor mold, develop effective sampling strategies and interpret laboratory results, all in the context of current mold-control and remediation principles. Participants will acquire a detailed understanding of the methods used to investigate mold growth in buildings and types of samples to collect. Discussions will explore the biology of molds, the causes of mold growth, as well as mold control and common indoor molds.

Basic knowledge of biology, indoor mold and microbial sampling techniques.

Upon completion, the participant will be able to:

  • Differentiate among fungi, molds, yeasts and bacteria.
  • List factors responsible for mold growth.
  • Decipher the differences in primary, secondary and tertiary colonizers.
  • Design effective sampling methods.
  • Explain limitations in current laboratory analytical methods.
  • Gain skills on how to interpret laboratory reports.


  • An overview of various types of molds
    • What is mold and what makes it grow?
    • What health effects are associated with indoor mold growth?
  • How to recognize indoor mold growth
    • Factors favoring mold growth
    • Signs of mold growth
    • Conducting a visual inspection and categorizing the extent of the mold contamination
  • How to develop effective sampling strategies
    • Sampling objectives
