SUCCESSFUL REFURBISHMENT OF 13 YEAR OLD REFUGE CHAMBER
Written by Brad Whittaker, Service Manager
MineARC’s Refuge Chamber Refurbishment Program transforms damaged, worn or second-hand chambers into fully functioning, certified refuge chambers that look as good as new. In the first half of 2017, MineARC successfully refurbished 26 chambers. One of which, was thirteen year old chamber MA-80 from Gold Fields St Ives, a gold mine located 20km south-east of Kambalda, Western Australia.
Following a refuge chamber audit conducted on site, the Series II 12-Person HRM (the original Standard Design) Refuge Chamber with a free-pour chemical scrubbing system was returned to MineARC Australia’s manufacturing facility in Perth where it underwent a complete transformation by MineARC’s qualified workshop technicians.
Internally, MA-80’s Series II Scrubbing System was upgraded to a Series IV Scrubbing & Control System with Aura-FX Digital Fixed Gas Monitoring and pre-packaged MARCISORB Chemical Cartridges for superior scrubbing capacity. The Series IV unit plays host to an intuitive digital controller interface to manage and monitor all chamber power and lighting, motion sensor logging, and an intelligent voice audio navigation (iVAN) system to guide occupants through operational procedures. MineARC’s Aura-FX Digital Gas Monitoring System features dedicated, reliable sensors, and has the ability to individually monitor up to eleven gases via a series of user-friendly, digital screens. The system includes audible voice alarms which will prompt occupants to replace scrubbing chemicals or adjust oxygen supply levels into the refuge chamber as required, reducing the risk of human error during an emergency.
The MineARC Refuge Chamber Refurbishment Program is available to MineARC and non-MineARC Refuge Chambers alike, thus converting your non-MineARC chambers into a fully functioning part of your MineARC fleet.
