In a chemical industry, the electrician's department is cutting away from where it is made. Is that ok
Maintenance work more frequently, prone to researchers thought paralysis most of chemical enterprise production equipment to a certain cycle will be planned maintenance, equipment operation process is often due to the sudden failure or accident, must be not shutdown or temporary shutdown of the maintenance and repair. These constant repair work makes it easy for management and maintenance staff to become accustomed to paralysis and increase the chance of an accident.
Are prone to static electricity and spark ignition source such as chemical equipment pipeline adopts metal materials, more cannot leave the process of inspection when hot, beating, sometimes also need to enter the up and down the tower, tank, or stereo interleaving, susceptible to electrostatic and spark ignition source, greatly increases the maintenance of fire hazard.
Make the change to normal production chain Chemical enterprise production process is complex, often production continuity is strong, harsh operating conditions, if a link or equipment failure, which will destroy the normal production chain, cause an accident. Chemical enterprise production equipment is in high temperature, high pressure or deep cold, negative pressure, and corrosion, wear condition. Equipment maintenance make originally in the normal state of continuous production interruption, equipment status, such as valves, switches, etc.) and process parameters change, after the maintenance state of existing equipment and the process parameters returned to normal process, this process prone to error and the equipment failure, burning explosion accident.
Explosion accident prone to chemical enterprises in the production of raw materials and products are flammable and explosive, the characteristic of high temperature and high pressure, prone to leakage of chemical dangerous goods when maintenance or remaining in the equipment lines, in the commissioning phase may be remaining in the equipment or mixed with air, form an explosive mixture gas, once fires raging fires often and severe losses.
Most of the chemical enterprise maintenance of fire safety system is not sound Some enterprises only when hot and tank operation safety regulations, no for repair job content, the scope of special fire prevention regulations, construction requirements are not clear. Some enterprises even do not have the regulation that block blind board, permutation, clean in the repair. Such as compressed the sanming chemical synthetic ammonia plants before driving, parking for years after all did not use nitrogen for the displacement, water gas displacement directly when driving, two lives and injured two accidents.
