Abstract Behavioural-based safety (BBS) is a powerful tool that industries are integrating into their health and safety management system to reduce workplace accidents. This study examines the relationship between big five personality traits (openness, extraversion, agreeableness, conscientiousness, and neuroticism) and interventional measures (training, rewards, penalty, supervisors feedback, and co-workers observation and feedback) by conducting a survey using two questionnaires among 200 employees belonging to heavy engineering industries in Kerala, a state in the southern part of India. The reliability and unidimensionality of all the scales were found acceptable. Results after regression analysis show supervisor feedback as the most effective intervention for behaviour change in individuals showing both high agreeableness and conscientiousness. Training is beneficial for individuals with openness and rewards are effective for those with extraversion. These findings provide valuable guidance for researchers and practitioners for identifying the mechanisms to design an effective interventional strategy for an organization’s BBS program based on worker’s personality traits.

1 Introduction Industries around the world are switching to proactive safety culture to reduce the inevitable injuries and risks involved in routine operations. Proactive safety culture is a result of personal and social values, attitudes, competencies and behavioural patterns that defines an organization’s attention to its safety and health initiatives and practices (Health and Safety Commission 1993). Such a system can only be attained by improving worker’s morale and belief in the safety culture of the organization. Behaviour-based safety (BBS) has shown significant results in terms of lowering unsafe behaviours, improving safe behaviours. BBS as a system not only foster * Vivek Kanjiyangat [email protected] 1

a safety culture in industries but also helps in preventing industrial accidents and reduces lost-time injuries (LTI) in a workplace. Although it is known that 80–90% of occupational incidents involve human factors (Hale and Glendon 1987), in recent years, the focus of research attention has been on organizational and environmental factors, rather than individual-level variables. To minimize the at-risk behaviour of the individuals, we direct or modify the
