SAFEX Paper: Guangzhou Shenzhen Hong Kong Express Rail Link
23 May 2011
Guangzhou-Shenzhen-Hong Kong Express Rail Link: An overview of the explosives aspects in a quantitative risk analysis for the road transport of cartridged emulsion explosives and accessories through a densely populated area.
The construction of approximately 15 km tunnels through rock involves the safe transport of substantial quantities of cartridged emulsion explosives, detonating cords and nonelectric (shock tube) detonators through densely populated areas. Bulk explosives are manufactured on site and are not part of this study.
A risk analysis has been undertaken by ERM (Environmental Resources Management (ERM)) on behalf of MTR Corporation Ltd for the transport operations involved with these media. In support of this, the authors participated in a review of explosives safety issues.
This analysis includes an assessment of prior incidents with similar explosives, the relevant physico-chemical properties of these energetic materials, available test data, credible insult scenarios during road transport, notably collisions, fires and damaged/off specification explosives and some possible approaches to mitigation. This paper will focus on the explosive emulsion aspects of the study.
The presentation is based on published reports which were part of a comprehensive overall QRA study conducted by ERM-Hong Kong Ltd.
