AIHA, the Association for Industrial Hygiene, is the largest association that exists to connect professionals in the business of worker safety, clean work environments and workplace health. (See photos here of the 2012 World AIHA Conference in Indianapolis.)
Is this guy safe from mold? Answer below*

Last week, the association released a long-awaited position statement on mold.

AIHA statement on mold  The statement isn't that compelling for a general audience (sorry, but let's be honest). Nevertheless, it's important to know a statement has been released. As for an excerpt -- well -- the document closes with the following:

"IHs and other IEQ practitioners should approach mold, water intrusion, and IEQ investigations with the same mindset they use when they approach all investigations."

The process includes three of the five key industrial hygiene elements: anticipation,
recognition, and evaluation. While the IH can reasonably anticipate that there will be
mold exposures associated with water intrusion, mold may or may not be the primary
cause of any health effect(s) that may be experienced by the occupants. The IH should
ensure that, while investigating mold-related complaints, whether apparent or reported,
active consideration of other possibilities affecting IEQ in the space is an essential part
of the investigation.

In addition to mold-related exposures, contaminants that are both directly and indirectly
associated with water-related damages may also be affecting the occupants. These
contaminants may include, but are not limited to:
• particulate and gas/vapor contaminants associated with improper combustion ventilation or improperly operating utilities, such as carbon monoxide, nitrogen and sulfur compounds, soot and other fine particles, fuel and other volatile organic compounds (VOCs), etc.; 
• VOCs from construction product degradation and/or off gassing, such as formaldehyde and other aldehydes, phenolics, and amines; 
• organisms that proliferate under damp conditions or when maintenance is substandard, such as bacteria, amoeba, dust mites, cockroaches, and rodents; and, 
• animal and chemical-based allergens already present and/or exacerbated by the water damage. 
Many potential contaminants may be present along with mold damage that can affect
health or the safety of investigators, remediation workers, and occupants. For example,
failure to recognize the presence of asbestos, radon, or lead-based paint could lead to
their disturbance during investigative or remedial activities, unnecessarily creating a new hazard.

Finally, there is a need to recognize the potential hazards associated with
remedial alternatives that may lead to the introduction of pesticides, ozone, chlorine
dioxide, and other chemicals that could exacerbate existing health conditions or lead to
new health issues. "
