Indoor mold contamination emergency response: this article describes how you may decide that the moldy conditions inside a building are serious enough to treat as an emergency.

Watch out: because individual health risks and site conditions vary widely, no publication can always identify nor solve all problems caused by indoor air contamination.
But here we provide assistance that will help in identifying an emergency and more assistance that will help determine when you need to hire a professional.
Even a non-emergency situation may require expert professional advice on diagnosis of problem causes and procedures to clean up mold or to remedy other IAQ issues.
At page top and above left we show examples of severe indoor mold contamination. In the extremely mold-contaminated building shown at page top there is no question that if this building had been occupied, it should not be. In an interesting technical experiment the author tested every surface of every different type of building material found inside the structure. The results were interesting: different mold genera/species had strong preferences for different materials (no surprise). These variations underscore the importance of strategic sample location selection when screening less obviously contaminated buildings for mold. For example I found completely different mold genera/species growing on the surface of a hollow-core luan interior door than on its edges.
Definition of Mold Emergency: Five Conditions Indicating an Indoor Mold, Odor, or Gas Emergency
The US EPA identifies five conditions that require immediate or "emergency" response [we have added a few items]: 
Watch out: a mold-related indoor IAQ emergency condition may exist but may be less obvious, as we explain below.
In the moldy book photo shown at above-left we illustrate a more subtle but serious indoor mold condition. In an in-use basement library area we found books that from a distance just looked "a little moldy". But the air disturbance caused by merely walking past these books sent visible clouds of green Aspergillus sp. mold spores into the air in extemely high concentrations - a condition we verified in our laboratory
Worse, when the remediators installed rapid dehumidifying equipment, the sudden plummet in indoor humidity so excited the Aspergillus that it sent still much higher levels or spores into building air. Proper dust and mold containment measures were very important at this building to avoid jeapordizing people occupying the in-use upper floors.
