Meanwhile, the secondary taxonomy is given. According to the established hazard taxonomy, three hazard identification methods are set up, which are system and job analysis, unsafe events analysis and safety information statistical analysis. For each method, applicable objects, working process and application example are given respectively. The hazard taxonomy and identification methods have been put into practice in a number of service providers in China, the results show that the taxonomy and identification methods have highly practicability.
