Not Asbestos i know but when working on the Gold Mines in South Africa at some 16000 feet, as a Blaster in the Stopes, ( only Max of 3 Foot Six in Height for 8 to 10 Hrs a day on ones Knees) there was a lot of Dust from the everyday blasting , and caused many many to develop Pneumoconiosis of the Lungs which is also a terrible thing to have , watched my dear Uncle die of it,( Silicosis) after being such a well Built and strong Man, just withered away.
In those days unfortunately the Ruling on safety measures down the Mine was not great at all, so the work practice that many followed was one of sheer neglect! Me too , as we were supposed to Wet everything down before and after a Blast which many never did!
I was one of the very lucky ones thogh, came through the 4 Years underground with clear Lungs! Lucky me!!
