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.
Multi-Service Vehicle – Virtual Tour
Multi-Service Vehicle – Front View
The ‘face’ of the TunnelSAFE MSV Design 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 – Interior View
Inside a TunnelSAFE MSV 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 MSV 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.
Multi-Service Vehicle – Rear View
A secure cabinet at the rear of the TunnelSAFE MSV Design houses the refuge chamber’s UPS battery back up (Uninterruptible Power Supply). The UPS is a fail-safe system that can power the refuge chamber’s internal life support systems for a minimum of 36hrs, should mine power become cut-off.
Also at the rear of the chamber is the Compressed Air Management System (CAMS), which allows regulated compressed air into the refuge chamber when the pressure inside drops below 200Pa. This process optimises mine air usage and guarantees against over-pressurisation of the refuge chamber.
CAMS’ gas toxicity monitor automatically diverts compressed air if oxygen levels in the airline fall below a set level (18% oxygen in free air), signifying air contamination. Additionally, the incorporated flood protection valve automatically shuts down compressed air to avoid catastrophic and costly chamber damage in the event of water ingress.

Rail Mounted Chamber – TunnelSAFE Rail Design Rail mounted chambers can be mounted or fixed to a tunnelling project’s existing rescue train; providing a portable safe haven for site 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. ENQUIRE
