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).
