Abstract :
In pharmaceutical factory buildings (PFBs),
numerous gaseous substances are suspended in the air
due to poorly designed production areas. In most PFBs,
fenestrations are limited, though they provide some
ventilation and workers’ access to the natural
environment. This paper assessed selected PFBs designs
to ascertain the adequacy of indoor airflow and air flush
as well as lighting and sound needed for the removal of
suspended gases largely harmful to human health. Using
a quantitative approach, fourteen PFBs were audited by
taking dimensions of the production area alongside data
on the quality of air, sound, and lighting. Findings
benchmarked against the global standard required for
factory designs to maintain wellbeing revealed eight PFBs
had unacceptable design features; It was found that a
unit increase in HCHO was found to increase the
temperature by 15.268oC and 98.3% of the variation in
air velocity is explained by airflow while only 0.5% is
explained by PM1.0, PM2.5, PM10. Workers’ complaint of
illnesses was traceable to these poor design features. The
paper recommended a need for re-evaluation in the
architecture of PFBs intending to provide a healthy
working environment for PFB workers in Nigeria.
