The effect of indoor environmental quality on the productivity of factory workers: A case of pharmaceutical factories in Southwest Nigeria

Abstract

The indoor environment of pharmaceutical factory building is known to be a very active place with industrial equipment, machineries, full of light, noise, particulate matter, and other gaseous elements. Having this all-in-one place can be a challenge to the wellbeing and possibly the productivity of the workers of the factory. As a result, the study investigated the effect of indoor environmental quality (IEQ) on the productivity of the pharmaceutical factory workers. This review of relevant literature from e-books, articles, conference proceedings, technical reports, textbooks, thesis and periodicals was conducted between 2010-2022. 14 pharmaceutical factories were investigated within 13 months (October 2020-November 2021). The factors of indoor environmental quality influencing workers’ wellbeing as well as their productivity, were thoroughly investigated using a strategic procedure. It was discovered that the factors involved in a pharmaceutical factory building's IEQ and the productivity factors of the workers were complex and diverse. This paper concludes that the previous studies reviewed do not show that indoor environmental quality of PFB have any significant impact on the productivity of the pharmaceutical factory workers.
