Description
Summary:Department of Occupational Safety and Health (DOSH) of Malaysia is very concern on a safety and healthy work environment for all employers and employees.Currently the number of fatality has been increased badly.To understand the situation, we study the behaviour of 18 safety culture variables used internationally.In this paper we examine the inter-relationship of variables which is based on correlation analysis.The minimum spanning tree is used to filter the information contained in the correlation structure consisting of 18[18-1]/2=153 correlation among the variables. To provide a better understanding about the tree, we compute the centrality measures. The result show that ‘Safety Procedure and Policy’, ‘Priority of Safety’, ‘Management Commitment’, ‘Involvement’ and ‘Work Environment’ should be of high priority in reducing the number of fatality.
