/Mine Refuge Shelters

Mine refuge chambers and shelters are complete safety systems built for the critical purpose of providing an isolated, breathable-air atmosphere for workers when the air quality in the working section has become compromised. They are intended for use when self-escape is not possible and workers need to wait for mine rescue teams.
