Safety at work is a global concern because accidents and injuries are the results of unsafe behaviour. Safety communication at the workplace is, therefore, necessary to improve safety. This study aims to analyse publication trends and thematic evolution in safety communication at the workplace over 45 years from 1975 to 2020. The review uses the Scopus database and various bibliometric indicators such as publication trends, citations, and authors’ keywords. Graphical visualisation of bibliometric indicators using VOSviewer is also presented. SciMAT was used to inspect the thematic evolution of safety communication research at the workplace. Safety communication research has fluctuated with less than 50 publications annually. This review is interested in several themes and dimensions in changes and evolution of safety communication. Essential themes in the first period (2006-2010) were “occupational-accidents”. The “questionnaires”, “safety-behavior”, and “risk-factor” themes became the most significant number of publications and citations during the second period (2011-2015). “Organisational-culture” was the high number of publications in the motor themes during the third period of studies (2016-2020). These five themes may be useful as a benchmark for occupational safety and health researchers and professionals focused on the art of safety communication at the workplace.
