The SkillPro-CSIR bag barrier has been subjected to extensive testing in Germany, the USA and South Africa
At Tremonia Mine in Germany, the bag barriers were tested in a full scale gallery against a wide range of explosion conditions. The images below show the bag barrier in operation in an underground explosion gallery.
Note the development of the initial methane explosion as it expands from the point of ignition (frames 1 to 3) The flame ignites coal dust which becomes involved in the explosion (Frame 4) and is then extinguished by the barrier (frame 5)
The bag barriers can be seen in the foreground silhouetted against the flame and the effectiveness of the barrier is evident when the flame is extinguished.
