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.
MineARC’s TunnelSAFE MSV Design Refuge Chamber is highly customisable to suit any tunnelling project and can be built to comply with British Standard (BS EN 16191:2014) Safety Requirements for Tunnelling Machinery or the ITA’s “Guidelines for the Provision of Refuge Chambers Under Construction”.
TunnelSAFE MSV Design Refuge Chambers can also be fitted with remote monitoring systems, or the client’s own remote control system.

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.
