ABSTRACT
As is shown in the statistical data from State Administration of Work Safety, 8724 construction accidents occurred with 2361 deaths from the accidents in the whole country in 2011. At the same time, with the increased awareness of enterprise risk management, construction enterprise safety in production situation tended to get better, but the total number of accidents is still large. From the perspective of risk management, it’s an effective method to prevent the hazard of dangerous source by applying safety signs to remind people to be alert of danger (Laughery, 2006)[1]. The effectiveness of safety signs directly determines accident occurrence (Yi-cheng Hu, Xiao-hong Zhou, Liang Wang, 2012)[2]. Therefore, enterprises widely use safety signs on the construction scene to avoid the risk originating in construction process. However, safety signs have shown considerable problems in current use and do not convey safety messages very effectively (Duarte et al. 2005, Liu et al. 2005)[3][4]. There’re many factors which impact on the effectiveness of safety signs. For instance, safety climate, individual characteristics and so on. In existing research, the evaluation of safety signs’ effectiveness is mostly focusing on the design and installment (Peng-hong Du, 2007; Jing Jin, 2010; Jing-peng Yuan, 2009)[5][6][7]. Because the effect of safety signs is decided by actor and environment, it’s necessary to evaluate the effectiveness of safety signs from the perspective of cognitive process and provide practical foundation for improving the effectiveness.
