To eliminate construction-related accidents, implementation of safety program is regarded as a key strategy by both government and private sectors. Several studies, conducted by Hislop (1991), Tam and Fung (1998), Hinze and Gambatese (2003) and Findley et al. (2004), revealed that outstanding safety performance is closely related to construction projects where an effective safety program is established, implemented and maintained. Effective safety programs can substantially reduce accidents because they can help management to eliminate unsafe practices by workers and can also create safe working environments (Anton, 1989; Abdelhamid & Everett, 2000). Additionally, Henshaw (2004) stated that an effective safety program could result in a triple win; workers' lives would be saved and protected, cost would be reduced and returns on investments would be maximized, and workers' morale and motivation would be raised which, in turn, would result in the production of high quality products and services.
