Dangerous chemical and supervision: big new energy material leaked bums and buffer tank leak burning

On July 2, 2020, the xinjiang production and construction corps shihezi big new energy co. , LTD. Poly project the disproportionation reactor in the process of nitrogen replacement, drain valve joint fracture caused by pipeline vibration, which leads to the material ( Dichlorosilane, trichlorosilane, silicon tetrachloride) Leakage and explosion, spread to nearby trichlorosilane buffer tank leak burning.

in addition, this year on March 21, hubei xing silicone material co. , LTD before repair tank replacement is not thorough, ball valve is not effective partition, lead to residual silicon powder leakage flash, three people burn; On June 14, hebei tangshan coupling silicon industry co. , LTD. Discharge of the wastewater containing flammable organic silane, in the absence of electrostatic export facilities rain heavily accumulation at the end of the riser energy ignite fires.

please local emergency management departments at all levels urge guide jurisdiction involving polysilicon, organic silicon, chlorosilane manufacturing enterprises to further strengthen the understanding of the intermediate products, by-products dangerous characteristics, strengthen the risk, improve the leakage protection, anti-static measures, strict inspection, special operation safety control, solar photovoltaic (pv) network, urged relevant enterprises will learn three years into the hazardous chemical materials safety rectification action listing issues list and system. Polysilicon industry in recent years the rapid development of the central and western regions, will be strictly the polysilicon production enterprise new, change, expansion project safety, enhance the level of essential safety, solar energy, we resolutely prevent major accidents.

in addition, xinjiang fire rescue team to release the fire of youth cast loyalty & ndash; — Remember the xinjiang shihezi team south meridian road of fire rescue team standing webmaster Ding Yali ', side also verified the big new energy production safety accident happened in July.

in July 2020, shihezi city big new energy company's polysilicon project 803 c the disproportionation reaction distillation workshop column chlorosilane spill, detachment disposal force arrived at the scene, the scene was a lot of hydrochloric acid and silica white smog, at any time is in danger of explosion, China solar power network, such as not timely financial consequences. Ding Yali after site investigation, volunteered, leading manufacturers and technical personnel risked his life in deep internal disaster site, success will be the valve closed. During the evacuation, and fellow technicians accidentally fell from the stairs and loss of consciousness, comrade Ding Yali in air respirator pressure is about to run out of a time of crisis, the personal life and death out, run out whole body energy to technicians carried out successfully, transferred to safe areas, utmost ground to avoid casualties and property losses, the party committees and governments under the high praise.
