Dynamic Security Evaluation To The Construction Site

As the construction industry is one of the pillar industries of national economy,it hasa great influence to the economic development and social stability of our country.Interms of construction production situation in China,Production safety it faces is a bigchallenge,To strengthen the safety management in construction site is the essentialmeans to ensure health and sustainable development in construction.The multi-factor, multi-variable, multilayered makes the hazards in construction sitequantity, wide range of distribution.Hazards in construction process is not fixed, but in aconstantly changing dynamic process,This makes the safety management difficulty inconstruction site.At the construction site, safety issues, it throughout the constructionprocess, therefore, strengthening the safety management in construction site in eachperiod to control the hazards is necessary, it requires constant hazard identification.This article will research on the identification of the hazards in construction site,analysis hazards of quantity in the different periods and its existence, and carries on therisk assessment.For the large numbers of hazards in the construction site,In order toavoid the omissions and repeat in the process of the identification.In hazardidentification, hazards can be divided into global and local hazards.Global hazards canbe identified from workers, construction machinery and equipment, constructionmaterials, construction environment, construction technology and constructionmanagement and so on.Local hazards can be identified from workers,constructionmachinery and equipment, construction materials and so on.The result of the globalhazards evaluation is comprehensive risk value, To local hazards, according to thenumber of worker and the type of work, the amount and type of construction machinery,the type and quantity of construction materials to insure the individual riskvalue.Finally,use the individual risk value to correct the global comprehensive riskvalue.This risk assessment combined system comprehensive risk assessment to thesingle hazard risk assessment.This method can make full use of the current safetyassessment technology, it makes the hazard evaluation more comprehensive andreasonable, the evaluation results more accurate, reliable and more conducive to theconstruction site safety management.
