Refuge Chambers for Tunnelling Construction
- TunnelSAFE Refuge Chambers

Emergency refuge forms an integral part of a tunnelling project’s wider Emergency Response Plan (ERP). In emergencies where personnel become trapped without adequate ventilation and evacuation is no longer safe or practical, refuge chambers are designed to provide a secure ‘go-to’ area for personnel to gather and await extraction.

TunnelSAFE chambers can be built to comply with European Standard (EN 16191:2014) Safety Requirements for Tunnelling Machinery, the British Standard (BS 6164:2011) Code of Practice for Health and Safety in Tunnelling in the Construction Industry, and the ITA’s “Guidelines for the Provision of Refuge Chambers Under Construction”.

Custom TunnelSAFE Chambers

Underground construction and tunnel design have several known risks. Hazards common to such work include exposure to air contaminants, fire, and other emergencies.  Mitigation against these dangers consists of the provision of refuge chambers to provide a safe ‘go-to’ area. All risks must be taken into account when managing safety underground.  

As with tunnel design, refuge chambers can be customised to fit the applicable industry standards and requirements of the project. When a traditional option is not appropriate, thinking outside the box can result in better quality and better safety management.  MineARC Engineers will work alongside our clients to ensure the supplied shelters meet the needs of the project as well as provide exceptional safety measures.
