This thesis critically examines dominant conceptualizations of safety crimes – offences by corporations that seriously injure and kill workers – within the Alberta oil and gas industry. Using critical discourse analysis, and relying on and Foucaultian and Marxist literatures, the thesis critically examines the extent to which government fatality reports, workplace safety education campaigns and court decisions characterize safety crimes primarily as ‘accidents’ caused by ‘careless’ workers. Two main discourses were found: first, workers were responsibilized, effectively blamed for their own injury and death in the workplace while employers were characterized as largely good and law-abiding; second, serious injury and death was (re)conventionalized as the regrettable but largely unintentional and unavoidable side effect of capitalist production. In the process, the underlying causes of safety crimes, including weak and under-enforced laws and a socio-economic context that prioritizes profits over worker safety, remain untouched.
