http://news.qq.com/zt2010/nanjingblast/index.htm During the demolition of Nanjing Plastic Factory No. 4, an acrylic pipeline was broken, resulting in multiple casualties. Why did no major accidents occur during normal production, but such a tragic accident happened during the shutdown and demolition process? How can we ensure safety during the maintenance of petrochemical plants? We welcome everyone’s suggestions!
In fact, there isn’t enough emphasis placed on this aspect in terms of awareness. Our facility was also demolished last year, and everyone from management to employees attached great importance to it; the time required to purge each pipeline was twice as long as usual, and all the gutters and septic tanks were sealed tightly with soil! Security checks are required every time a pipeline is dismantled! We completed the demolition successfully! If safety measures can be refined in daily life and everyone’s awareness of safety improves, many accidents can be prevented from occurring in the first place!
Piping purging, verification prior to ground work, and completing all necessary construction procedures are important measures to prevent accidents.
According to online reports, it was the propylene pipeline belonging to Jinling Petrochemical that ran through the premises of Plant 4. Before Plant 4 was shut down for demolition, this propylene pipeline should have been taken out of use and thoroughly cleaned. It seems that the relevant authorities neglected this pipeline, which led to this tragic accident.
The main issue is the lack of safety awareness, and leaders also bear undeniable responsibility. The supervision on site was also inadequate.
The rough construction methods, coupled with a lack of understanding of the layout of underground pipelines, make it dangerous to use underground pipelines for transporting propylene. It is difficult to determine the degree of corrosion or damage to these underground pipes; even if they are not damaged, there is still a risk of leaks after prolonged use. It is therefore better to use above-ground pipelines for transportation.
