Norwegian Tunnelling Rescue Container – Virtual Tour
Nordic Chamber – Front View
The ‘face’ of the TunnelSAFE Nordic Design is designed primarily for easy identification and quick access during an emergency. The strobe lighting, warning siren, bright yellow exterior and wide-band 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.
Nordic Chamber – Side View
The robust skid base of the TunnelSAFE Nordic Design is constructed from high-strength steel (Bisalloy), allowing the chamber to withstand frequent movement. The skid base is formed by strong, abrasion-resistant, quenched and tempered steel plate. Forklift slots (250 x 100mm) and front mounted 25mm steel plate push blocks aid chamber positioning.
A side escape hatch is inward opening and is accessible internally and externally.
Nordic Chamber – Interior View
Inside a TunnelSAFE Nordic 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 Nordic 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.
The chamber includes an electrical outlet (power socket).
Nordic Chamber – Rear View
A blast shield at the rear of the TunnelSAFE Nordic Design safely 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 24hrs, should mine power become cut-off.
