Preliminary Determination for Mold

Preliminary Determination for Mold
After the initial HVAC system component inspection, a
preliminary determination must be made by the person
performing the inspection regarding potential mold
contamination. Making a determination involves the
collection, analysis and summary of information to
identify areas of moisture accumulation and potential
mold growth. A preliminary determination may indicate
the need for further assessment by an IEP and/or other
appropriate professionals (See IICRC S520).
3.3.2 Surface Mold Growth
If the preliminary determination indicates a small,
isolated area of mold growth on a surface layer of
condensation on painted walls or non-porous surfaces,
and mold growth has not occurred in concealed areas,
the use of an IEP generally is not necessary and the
mold usually can be removed as part of a regular HVAC
maintenance program (See IICRC S520).
3.3.3 Limited Mold Growth
If the preliminary determination indicates a limited
amount of visible mold confined to a specific area, (e.g.
a small area of a mechanical system that is not in the
path of the major air circulation system of the structure),
the use of an IEP may or may not be necessary and the
restorer or remediator’s professional judgment is needed
