Over the years, BBS has been applied successfully by many researchers in various settings such as clinical medicine (Dickerson et al., 2010), manufacturing (Hermann et al., 2010), mining (Hickman & Geller, 2003) and institution office (Al-Hemoud & Al-Asfoor, 2006). Moreover, BBS was found to be a promising way to further prevent accidents. Many researchers analysed the OSH records of enterprises which implemented BBS and the results revealed a significant decrease in incidents across groups following the BBS implementation (see e.g. Krause et al., 1999).
