In Cambodia, a deminer was working in the prone position and set off an anti-personnel type 72 Chinese tilt mine. The resulting blast went over his head and did not damage his exposed hands. The blast over-pressure sucked air and dirt into his helmet visor and punctured his eye, which recovered fully. This over-pressure problem was caused by an air gap between the helmet visor and his protective jacket. Within seven days a new visor was dispatched from the manufacturer to my specifications, tested and found to remove the air gap problem. As part of the daily safety checks carried out on deminers it is necessary to ensure that helmet and protective jackets are properly fastened.
