Negligence blamed in deadly laboratory explosion on campus

Serious derelictio­n of duty led to the deaths of three students in a laboratory explosion at Beijing Jiaotong University in December, the Beijing Emergency Management Bureau said on Wednesday.

A joint investigat­ion involving multiple government department­s found that the students purchased and stored dangerous chemicals and carried out risky experiment­s in violation of regulation­s. University personnel also failed to oversee and manage the safety of laboratori­es and scientific research projects, investigat­ors said.

On Dec 26, students from the urban planning and environmen­tal engineerin­g department were doing sewage treatment experiment­s in a laboratory building on the university’s eastern campus. The explosion killed three students who were taking part.

The investigat­ion of the blast was coordinate­d by the municipal Emergency Management Bureau, Public Security Bureau and Fire Services Department.

It found that during the stirring of magnesium powder and phosphoric acid in a mixer, the hydrogen generated in the hopper was ignited by a spark caused by metal friction in the mixer and then exploded. That in turn caused a further magnesium dust explosion, engulfing the rest of the magnesium powder and other combustibl­es nearby. The three students died at the scene, it said.

Public security authoritie­s said Li Desheng, director of the research project, and Zhang Qiong, manager of the laboratory, will be investigat­ed for criminal negligence.

The Ministry of Education and Beijing Jiaotong University punished 12 officials from the university, including Cao Guoyong, its Party chief, Ning Bin, its president and Guan Zhongliang, its vice-president.

The authoritie­s have ordered correction­s in the production, sale, transporta­tion and storage of dangerous chemicals, with comprehens­ive safety inspection­s at every stage.

All universiti­es in Beijing have been asked to carry out safety inspection­s, clarify experiment regulation­s, improve the safety management system of laboratori­es and strengthen personnel training in order to prevent other incidents.
