Abstract
Safety culture has been widely accepted as a crucial aspect in construction organisations. Despite its popularity, there is confusion on the actual meaning of safety culture. Another concept called safety climate has been used interchangeably with safety culture and has fuelled more perplexity. This paper aims to clarify the meaning of both concepts and discuss the differences between the two through a literature review. It is argued that safety climate is part of safety culture, that is, it is the psychological dimension of safety culture. Furthermore, this paper has developed a framework to show the overall concept and contents of construction safety culture, which includes the cause, contents, and consequence of safety culture. Measurements are also proposed for construction organisations to measure their safety culture and improve their safety performance continuously.
