Fire is one of the greatest threat to the tunnel. A large number of research results of metro and tunnel fire prevention technology have been accumulated in Europe, America and Japan. In these country and region, a series of standard have been applied to tunnel engineering. Based on the standards of...

Small and medium-sized enterprises are an important part of China's economy. They play an important role in China's economic construction. The safety is first is the necessary condition to ensure them orderly development. The first, the safety management characteristics of small and medium enterprises...

It was introduced on the requirements of explosion venting and the determination method of venting area for the relative closed building, and the application condition and scope were described in detail. The big spray plant including some complex workpiece was simulated by the FLACS, and the influences...

Zhejiang is a major province for the production and consumption of hazardous chemicals. Chemical industry safety accidents in Zhejiang province since 12th Five-Year Plan were analyzed and a dynamic risk assessment model for chemical enterprises was proposed. Some risk factors, such as the attributes...

Spill fires during production and storage may cause large damage and even lead to massive explosions. In this article, the accidental risk and rescue measures of spill fires were discussed. Based on accidents happened before, there are four typical scenes may lead to spill fires. It is essential to understand...

In order to control fire chain risk of hazardous chemical tanks, a method of risk analysis and control on fire evolution of hazardous chemicals is proposed based on the complex networks theory. Firstly, fire risk factors of hazardous chemical tanks were analyzed and screen initial risk events, transitive...

In view of urban public traffic safety, the accident tree analysis(ATA) theory was applied to construct an accident tree model which taken the children fall accident in the escalator area as the top event. According to the accident tree model, the Boolean algebraic function expressions of the accident...

In this paper, a novel inert polymer adsorption material for hazardous chemical oil, named as Zhong-Yi FG strong adsorption material, is proposed in emergency disposal to deal with pollution of sudden chemical spill into rivers and oceans, and to recover chemical leakage. In this paper, a simple and...

As a decentralized infrastructure and distributed computing technology, block chain has attracted the attention of government departments, financial institutions, and technology companies. Within the characteristics of decentralization, time series data, collective maintenance, security, and trust ability....
