Gantry Mounted Chamber
– TunnelSAFE Gantry Design
Gantry mounted chambers are designed to be installed at the rear of the Tunnel Boring Machine (TBM), providing a fixed safe refuge solution for the life of the tunnelling project.
The TunnelSAFE Gantry Design (GD) is available in a standard and wide design, dependent on the size of the cutting head infrastructure and project requirements.

The ‘face’ of the refuge station 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.
112 dBA motion activated siren to allow for easy location of the refuge chamber in an emergency.
Extra low voltage green and red LED lighting to allow for easy identification of the refuge chamber in an emergency.
Safety and operational signage in reflective stickering for high visibility underground. Translation into a second language available.
12mm porthole viewing window, compliant with Australian Standard 2208. Blast shield protection available upon request.
High durability white paint for underground visibility. Sand blasted to 2.5 grit.
Fire extinguisher for external use only. Optional for non-Australian orders (supplied separately as Dangerous Goods).
Fire blanket with BSI certification (AS/NZ S 3504) located inside chamber.
Outward opening door, featuring double locking rotating handles. The vacuum tested seal maintains a positive internal pressure.
A custom engineered frame to fit any fix point.

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.
Air conditioning is vital to combat the potentially fatal effects of heat stress, caused by the occupant’s metabolic activity, as well as any ambient heat.
Operating procedures are located on the wall of the refuge chamber, as well as within hardcopy manuals. Operating procedures can be translated into a second language.
MineARC’s MARCISORB CO2 and MARCISORB CO cartridges provide superior scrubbing capacity, are easy to load, safe to handle, and can store for long periods.
The MineARC Compressed Air Management System (CAMS) is a dedicated air management unit designed specifically for MineARC Refuge Chambers.
Real-time gas monitoring with live analysis and voice prompting. Monitor up to 11 gases at any one time.
The TunnelSAFE uses active chemicals and MineARC’s extra-low-voltage scrubbing system to ‘scrub’ the build up of harmful CO2 and CO from the chamber.
The digital controller interface is the operational hub of the refuge chamber. From here, all power, lighting & scrubbing systems can be managed with the push of a button.
MineARC seating is ergonomically designed to provide suitable comfort during entrapment. Made from durable, hard wearing fabric, the seating provides 500mm of space per person.
