"Safety First, Prevention First, Comprehensive Management" policy, to promote the basic management of enterprise safety production, improve production and operating conditions, eliminate hidden accidents, effectively prevent the occurrence of serious and serious accidents, and effectively safeguard the safety and health of my project workers in the labor process, according to the "Provincial Department of the Su Jiaogong quality ﹝ 2011 ﹞ 25". 2011﹞25 "," on the transmission of the Ministry of Transportation (on the construction of highway bridges and tunnels to carry out safety risk assessment of the pilot work of the notice> notice "document requirements, in my department in-depth implementation of the project construction safety risk assessment work investigation, monitoring, now on the relevant matters to formulate the program As follows:

One, the guiding ideology

Risk assessment is to identify the risk factors from the source of construction, a reasonable determination of the risk level, give up or modify the residual risk of a high engineering program, proposed risk treatment and monitoring measures to carry out systematic risk management, improve risk management, safeguard the safety, protection of the environment, to ensure that the construction period, control the investment and improve the efficiency. To improve the safety monitoring work system as a carrier, and actively build "group prevention, group control, group control" of the safety production network, effectively prevent the occurrence of various types of accidents and occupational hazards.

To project construction safety risk assessment pilot work is currently being carried out in the province's highway and water transport projects, "safe site" construction, to prevent collapse accidents, mainly in the project safety hazard investigation and management of the two activities, in accordance with the risk level of the implementation of differentiated management, will be limited energy, financial resources into the more needy! The Government has implemented differentiated management according to risk levels, invested limited energy and financial resources in more needed areas, reduced or minimized outstanding safety risks, and explored more effective work methods and measures. According to the assessment results of the preparation of operational and effective construction safety special program, so as to comprehensively improve the scientific level of safety management of the ** project, in order to achieve the safe production of this project to lay a solid foundation.
