It’s all dangerous to varying degrees. There is a range of conditions associated with it, pleural plaques, asbestosis and the worst, which my Dh had, mesothelioma. There is no cure. It’s a rare condition overall, (about 2500 cases a year in the UK) but because of his work, one in ten of his former colleagues have died of meso and others have the other conditions. It’s a very high attrition rate.
My brother also died of it last year. He was a motor engineer, in the days when brake pads were made of asbestos. Like my Dh, he was overall fit, healthy and active for his age until struck down.
Sorry for the loss of your husband & brother Suedonim.
I did a motor vehicle course at college. We were told never to blow the dust off the brake pads, only to brush the dust gently, which now I still think it could be airborne.
