The HVAC contamination type and the environmental

The HVAC contamination type and the environmental
impact survey must include a visual evaluation of
representative sections of the HVAC components and
the occupied spaces served by the HVAC system. This
evaluation serves to visually inspect conditions within the
HVAC system and verify the overall physical integrity of
system components and surfaces.
Information collected from the project evaluation should
be used to define the scope of the cleaning and
restoration project, cleaning techniques to be employed,
the environmental engineering controls required for the
workspace, and any unique project requirements.

4.1 Building Use Classification
Classifying the type of building and its uses is an
important part of project evaluation. Cleaning methods,
project specifications, environmental engineering
controls, and cleanliness verification methods may vary
among different buildings. Building classifications are
listed in Sections 4.1.1 to 4.1.8 of this standard. If the
HVAC system restoration project is being conducted as
part of a larger mold remediation project, it is
recommended the building’s usage classification be
determined by an IEP to assess the overall impact of the
contamination present and the corrective cleaning
actions specified to remediate the contamination.
