Most frequently happening accident in construction working sites was fall in high and dangerous position. Most of fall accidents resulted in serious injury or death of workers. In this research was analysed recent safety accidents for three years from 2010`to 2012 and was developed the safety equipment to be able to efficently prevent and reduce fall accidents. This new safety equipment can be easily fixed to the reinforcing steel or steel girder etc by the fixing hook of life saving line and is comfortablely portable because of its light weight. The questionaire study of the developed equipment was performed to investgate the problem in the view point of using in real sites. The result shows that the new fixing fook can reduce fall accidents and satisfy construction workers.
