In mid-June, Sweden-based Jama said its mobile underground chamber, the MRC 2, was available for sale.<\/p>\n\n\n\n
The stainless-steel chamber seats up to eight people comfortably at room temperature and has access to clean, fresh air without masks. It is also protected from gas and dust.<\/p>\n\n\n\n
To lower the temperature in the rescue chamber, it is showered on the outside with water and can therefore maintain a normal comfortable indoor temperature. Air from a tube maintains an overpressure that prevents pollutants such as dust, smoke or gases from penetrating. <\/p>\n\n\n\n
\u201cThis is built up in two steps to ensure overpressure throughout the chamber, even in the air lock,\u201d the company said. <\/p>\n\n\n\n
The MRC 2 is powered by 230 volts, but if the power supply is interrupted, a reliable and well-sized battery pack is activated that lasts up to 50 hours; that capacity can be boosted if needed.<\/p>\n\n\n\n
Jama said the MRC 2 meets the current national\/international standards and guidelines such as EN16191:2014, HSE and ITA. <\/p>\n\n\n\n
