Chamber Exterior – Front

The ‘face’ of the refuge chamber is designed primarily for easy identification and quick access during an emergency.

The strobe lighting, warning siren and reflective signage alert passers-by to the chamber’s location, whilst the rotating door handles provide simple, straight forward access to the safety of the interior.

Chamber Interior

Inside a TunnelSAFE Gantry Design Refuge Chamber, a number of vital life-support systems combine to create a safe, ongoing environment for occupants. Systems include; primary and secondary air (oxygen) supplies, air conditioning systems, positive pressure systems, electrical systems, gas detection and a chemical scrubbing system.

The TunnelSAFE Gantry Design uses active chemicals and MineARC's ELV (extra-low-voltage) Scrubbing System to ‘scrub’ the build up of harmful CO2 (carbon dioxide) and CO (carbon monoxide) from the air inside the refuge chamber.

Comparison Table

Capacity Every refuge chamber is built with a certain rated occupancy in mind. The life support systems are designed to safely house this number of people for the designated duration.
