Relationship between perceived IAQ degradation and operational and
maintenance levels in buildings. (From Dorgan, C.E. and Dorgan, C.B.,

ing a variety of interim and permanent control measures. They describe LBP
hazards using numerical values; testing procedures to be used in conducting
paint, dust, and soil sampling, and analysis for lead; and clearance levels that
should be achieved before abatement actions can be completed. Because they
are performance guidelines, they describe good professional practice and, as
a consequence, have a high probability of being followed by lead professionals
in the absence of specific regulatory requirements.

VOCs
Voluntary guidelines for reduction of VOC exposures in newly constructed
or renovated office buildings were developed by the California Department
of Health's Indoor Air Quality Program. Guidelines included recommenda-
tions for design, construction, commissioning, and operation during initial
building occupancy. They included source control recommendations such as
(1) selecting building materials to avoid strong VOC emission sources, (2)
isolating construction zones in partially or fully occupied buildings, (3)
scheduling construction or furnishings installation to minimize buildup of
elevated contaminant levels before occupancy, (4) installing adsorptive mate-
rials before applying wet coating and other similar materials, and (5) using
low-emitting maintenance and housekeeping materials. Guidelines sug-
gested the use of building bakeouts (see Chapter 10) prior to occupancy.

Governmental voluntary initiatives
Federal and state government agencies can request that an industry, group
of industries, or building owners/managers voluntarily participate in pro-
grams designed to improve the quality of air in buildings. Most notable of
these has been USEPA's carpet initiative and dialogue.
