| The liquid chemicals is a biggest hazardous kind of the dangerous chemicals, its road freight volume big, the frequency high, the scope is broad, safeguarding transportation process safety of liquid chemicals is the key in the transports duty. This article utilizes the dangerous source theory of the analyzing cause factor of accidents theory as well as the breakdown tree analysis method (FTA) to recognize the risk of the liquid chemical highway transportation, analyze the inherent or the latent dangerous factor in the liquid chemical highway transportation process, and propose the dangerous source monitoring countermeasure of liquid chemical highway transportation. Then hazing used the accident consequence model to quantitatively attribute the harm to the public human body health along the route when occurring the accident of the fire, the detonation, the poison divulged in the liquid chemical transportation process. This article has established the 3- dimensional appraisal model of dangerous degree basing on the possibility, the gravity of the accident and the transportation enterprise safety control level. This model might carry on the generalized analysis qualitatively and quantitatively to highway transportation danger degree of liquid chemicals. Hazing applied the fuzzy mathematics theory and the gray system method to carry on the dynamic generalized analysis to the highway transportation enterprise safety control of liquid chemicals. Finally, applied the 3-dimensional appraisal model of dangerous degree which established and unified the Shan'xi some liquid gas transportation enterprise interior situation and the concrete transit route to carry on a dangerous appraisal and the analysis to the result. Through these may indicate this method to have the good feasibility in solves in this kind of complex problem. The assessment method this article proposed also has the certain model significance to the highway transportation of other types dangerous chemicals. |
