Change-Over Station - CoalSAFE COS​

The MineARC CoalSAFE Change-Over-Station (COS) is designed to aid underground personnel as they exit the coal mine during an emergency. The change-over station provides a secure ‘staging-post’ stocked with replacement breathing apparatus.

Inside the COS, breathing apparatus such as self-contained-selfrescuers (SCSR’s) can be changed over in safety while providing coal mining personnel the opportunity to regroup and continue to plan their escape. Each model features custom-designed storage to accommodate site requirements.
