Indoor air quality adversely affected by the -
of various pollutants released from building
materials, pesticides, or other chemicals used in and
around the facility. Some foam insulations and
particle boards contain formaldehyde, a chemical
preservative that slowly evaporates out of the
material and enters the building air supply.
Likewise, some fertilizers and pesticides used around
the exterior of the building foundation may infiltrate
the building and enter the air supply. There are
detection kits that can be used to test indoor air for
the presence of various pollutants. However, most
indoor air pollution problems can be remedied by an
efficient mechanical ventilation system that has
exterior air intake vents located away from pollutant

by termites or by careless plumbers and electricians.

3.4.3 Architectural Barriers. About 10 percent of the
population of the United States suffer from temporary or
permanent physical handicaps. Yet, until recently, few buildings
were designed for people in wheelchairs or on crutches or for the
visually impaired. However, the Americans with Disabilities Act,
PL 101-336 (effective July 26, 1992) will require employers to
make "reasonable accommodations" to facilitate people with
disabilities, including employees, visitors, and others. The law
states that architectural barriers should be removed when the
removal is "readily achievable." See also Uniform Federal
Accessibility Standards (FED STD 795).
