According to the S520, how are "settled spores" characterized?

Settled spores are characterized as Condition 2 according to the S520 standard, which refers to a specific classification of mold growth and its environmental conditions. In Condition 2, the presence of settled spores indicates that there is a need for remediation, but it is not as severe as conditions found in higher classifications.

Condition 2 suggests that while some fungal spores have settled, overall mold growth isn't extensive, and it doesn't indicate active growth or colonization that is typically associated with more severe conditions. Understanding these classifications is critical for remediation professionals, as it helps them assess the extent of microbial contamination and determine appropriate remediation strategies.
