Funniest thing I remember as a young Cpl back in 74, we were issued with the replacement magnesium batteries for the 77 set but no disposal instructions. So after 2 weeks exercise in High Range training area in Townsville we had collected quite a tidy sum of expended batteries. On return to 3 Task Force Lavarack Barracks asked where we were to dispose of said batteries and told throw them in the industrial waste bin. Next day the contractor rolls up to empty the bins (they were chockers) first bin up and into the garbage truck compressor on and one almighty bang as they exploded. After the smoke cleared away there was nothing left of the compactor at all. Was even funny still as we were sent out to clean up the mess off the roadway. New disposal instructions were immediately issued said batteries were to only be disposed of by burial.![]()
