In the last three decades, we've witnessed remarkable improvements in workplace accident rates, both fatal and non-fatal. These gains can be attributed to a concerted effort to optimise Standard Operating Procedures (SOPs) and upgrade machinery across industries, as well as improvements in leadership and management. However, a disconcerting trend has emerged, and over the last few years, these improvements have begun to plateau.It begs the question: Where can we find the untapped potential for further enhancing safety? In this free paper, we explore the the human factor, a layer of complexity that cannot be ignored. We explore how both physiological and psychological human factors can significantly impact safety outcomes as well as workforce productivity.
