Framework for Measuring Corporate Safety Culture and Its Impact on Construction Safety Performance

Abstract

This paper presents the results of a structural equation model SEM that describes and quantifies the relationships between corporate culture and safety performance. The SEM is estimated using 196 individual questionnaire responses from three companies with better than average safety records. A multiattribute analysis of corporate safety culture characteristics resulted in a hierarchical description of corporate safety culture comprised of three major categories—people, process, and value. These three major categories were decom- posed into 54 measurable questions and used to develop a questionnaire to quantify corporate safety culture. The SEM identified five latent variables that describe corporate safety culture: 1 a company's safety commitment; 2 the safety incentives that are offered to field personal for safe performance; 3 the subcontractor involvement in the company culture; 4 the field safety accountability and dedica- tion; and 5 the disincentives for unsafe behaviors. These characteristics of company safety culture serve as indicators for a company's safety performance. Based on the findings from this limited sample of three companies, this paper proposes a list of practices that companies may consider to improve corporate safety culture and safety performance. A more comprehensive study based on a larger sample is recommended to corroborate the findings of this study.
