Fisk and Seppanen (2007) stated that indoor pollutant sources
such as off-gassing of toxins from surface materials, equipment,
and furnishings, can affect employees’ work performance, speed
and accuracy. In addition, Fisk and Seppanen (2007) suggested that
humidification systems with poor condition and maintenance were
associated with significantly increased upper respiratory symptoms,
eye symptoms, fatigue, difficulty in concentrating, and skin
symptoms. Less frequent cleaning of cooling coils and drain pans
was also associated with increased eye symptoms and headache
(Mendell, Lei-Gomez, Mirer, Seppänen, & Brunner, 2008).
