to the interior of residences or commercial buildings. Modification of the
manufacturing process, solvent substitution, product reformulation, and
altering installation procedures are a few of the approaches available.
When VOCs are present indoors at elevated concentrations, modification
of ventilation rates is a control option for diluting and reducing these
concentrations. The American Society of Heating, Refrigerating and Air-
Conditioning Engineers (ASHRAE) has established standards for ventila-
tion rates for outside air per individual. The guideline is 15 cfm per person
(2). This guideline is designed to bring sufficient fresh air into a building
to minimize the buildup of contaminants and odors.
