Despite improvements in occupational health and safety due to technological advancements and the adoption of management systems, accidents continue to occur in the oil and gas (O&G) industry. These accidents are often linked to human factors. The emotional intelligence (EI) of workers, however, has the potential to influence some of the human factors that predispose to accidents. In this study, we investigated how the EI factors of workers influence their health and safety performance in the work place. A total of 124 O&G industry workers completed a web-based questionnaire. Five and 14 key success factors of EI and effective occupational health and safety management systems were respectively identified through a systematic evaluation of the literature. EI success factors of ‘being able to rule one’s own emotions to facilitate thinking’, ‘being able to deal with the emotions of others’ and ‘being able to discuss one’s own emotions accurately’ were found to have a relationship with health and safety performance of workers. The findings demonstrated that certain success factors of EI are vital for improving the health and safety performance of workers and that the development of these competencies should be part of the workers’ professional development.
