Intrinsically Safe Management About Electrical Circuit Of Concealed Work

In recent years, with national economy high speed development, electricityhasbecame one of the indispensable energy in the human production and living. Thedemand for electricity is becoming bigger. However, when the human benefit fromthe use of electricity, the number of fires caused by the improper use of electricity arealso increasing, which caused the huge economic loss.A large number of statistical data show that: in recent years, both from the firecauses and fire casualties and economic losses caused by electrical fires are largerthan other types of fire in China. According to the statistical data of the electric fireorigin, in recent years, in the electrical fire, electrical wiring fire about two-thirds.And electrical circuit of concealed work is difficult to manage. Electrical circuit ofconcealed work has the following technical issues:(1) Electrical circuit of concealed work is concealed, electrical circuit ofconcealed work exists in all kinds of engineering and most of the branch ofengineering, parcel by subsequent processes, strong concealment.(2) Electrical circuit of concealed work is difficult to rework, the high cost. Dueto electrical wiring to take cover engineering belong to the dark apply engineering, ifelectrical wiring problems, need to rework, could seriously delayed constructionprogress or caused great inconvenience to residents, and rework costs and losses.(3) Electrical wiring to take cover engineering monitoring is difficult and highcost. Due to the concealment of the concealed engineering electrical wiring, electricalwiring to take cover engineering is not easy to monitor, a problem was found to be noteasily, discovery is not easy to handle.The main research work of this paper is as follows:(1) Introduced the selected topic background, research status about electricalwiring to take cover engineering at home and abroad, and the characteristics of theelectrical wiring to take cover engineering as well as the existing problems; (2) The definition of the essence safety management are introduced, and thedifference of traditional safety management and the essential safety managementprocesses;(3) The use of accident cause theory analysis take cover engineering safety factorthat lead to accidents in the electric circuit, looking for reasons related to the accident,conditions and rules;(4) To take cover engineering unsafe factors in the electric circuit ofman-machine loop four aspects are put forward management measures, to reduce theprobability of accidents from the source.
