APPLICATION AND PROSPECT OF ENERGY ISOLATION IN THE INSPECTION AND MAIN-TENANCE WORK OF REFINING AND CHEMI-CAL ENTERPRISES
In chemical industry,especially in large-scale refining and chemical enterprises,due to the pro-duction demand,it is inevitable to carry out some local overhaul,maintenance,installation and cleaning and so forth.If the valve or switch is opened carelessly,it will cause the failure of energy isolation which will lead to flammable and explosive,toxic and harmful media,electrical energy,mechanical energy and other energy accidental release,thus causing safety accidents.The implementation of management measures such as ener-gy isolation,locking and tagging will enable effective isolation of equipment under maintenance or operation,preventing accidents and eliminating personnel injuries from the root.This is beneficial exploration and practice for chemical enterprises to prevent the injury to main-tenance workers during production process,to promote the visual management of production site and to realize the intrinsic safety of chemical maintenance.
