亲爱的同学们,

        首先，非常感谢大家今天上午能积极配合悉尼科技大学职工和当局的指挥，紧急有序的撤离事故现场，也非常感谢您的耐心等待。 

        现在，我就今天上午的化学品泄漏事故做一个综合通报。

        今天上午，我校员工发现储藏在1号楼2层的7瓶苦味酸中其中两瓶已经结晶，如果处理方式不当，苦味酸会在空气中化学合成，引发爆炸，情况非常复杂。为了我校师生的生命财产安全，防止引发爆炸危险，我校紧急联系了紧急服务部门，并将全体人员从1,2,3,4号楼撤离。

        新州警方(包括防爆小组)及新州消防和救援服务部门火速赶到现场。当局和悉尼科技大学安保人员共同着手处理，警方也将Broadway以及Chippendale段的Harris Street双向封闭。很不幸的是，很多媒体也火速赶到现场，随后网上开始出现大量不实报道。

        我很欣喜的告诉大家，危机已经解除了。只用了90分钟时间，大楼全体人员被撤离，紧急服务部门火速赶到，Broadway被关闭，危机被解除。苦味酸已被移除，我们回归正常。再次感谢您的配合，以及您在这起事故中表现的耐心。

Dear Students

First, many thanks to those of you who were involved in this morning's event - your orderly evacuation, your cooperation with UTS staff and authorities, and your patience is much appreciated.

I am now in a position to provide you with a comprehensive report of this morning's event. 

It was noticed this morning that two of the seven vials of picric acid stored on site (Building 1, Level 2) had begun to crystalise - in this form, the acid has the potential to explode if subject to shock or friction, fire or other sources of ignition. In line with the University's Environment, Health and Safety procedures, the situation was assessed and though an explosion was determined to be unlikely, emergency services were contacted and buildings 1, 2, 3 and 4 were evacuated as a precaution.

NSW Police Service (including the Bomb Squad) and NSW Fire & Rescue Service were very quick to respond and arrived at the scene in minutes. Authorities and UTS Security worked together to control the situation, with NSW Police closing Broadway as a precaution.

Unfortunately, the media was also very quick to respond with stories (many inaccurate) appearing online and news crews on site.

I am pleased to report that the threat was quickly neutralised - in only 90 minutes, the buildings were evacuated, emergency services arrived, closed Broadway and neutralised the threat, and the all-clear was given and we returned to business as usual. The speed with which events unfolded made on-the-fly communications a challenge so again, thank you for your cooperation and your patience.

Regards

Ross
