Multi-Service Vehicle Chamber
– TunnelSAFE MSV Design
Multi-Service Vehicle Chambers are engineered to be mounted to a multi-service vehicle; providing a portable safe haven for tunnelling personnel during routine inspections and maintenance works. As a long term safety option for the entire life of the tunnel, these chambers are robust and fully serviceable.

Multi-Service Vehicle Chamber – Front View
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.

Multi-Service Vehicle Chamber - Interior View
Inside a TunnelSAFE Rail 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 Rail 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.

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 seating is ergonomically designed to provide suitable comfort during entrapment. Made from durable, hard wearing fabric, the seating provides 500mm of space per person.

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.
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 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.
