Karzelek’s K-911 is a new personal protective device which allows underground miners to access breathable air in case of accidents. “It's a last-defence tool for miners, after all procedures have been extinguished or tried,” Pascal Morin, commercial development at Karzelek, told CIM Magazine. “If they're walking towards a refuge station underground and the smoke wall arrives... this tool can be deployed, and you can hook it up to the compressed air lines in an [underground mine].” The K-911 is an additional means to protect miners in case of fire and can be used for lumbar support and as a stretcher, survival tent and thermal blanket. According to Karzelek, the device maintains body temperature for injured workers and provides oxygen, keeping miners safe while they wait for mine rescue and evacuation.
