On joining my first ship in the RN,she was in a minor re-fit. I remember walking along the main drag( passageway) as the dockyard workers stripped lagging off the overhead pipes. The lagging was asbestos. It looked like flakes of snow as it fell. No one was wearing any breathing apparatus or protective clothing.
My next door neighbour has just had his old asbestos shed roof removed, it cost him £500 , and no one who was unprotected was allowed within about 20 foot of it.
At school we did all our chemistry labs using an asbestos square. My dad encouraged my interest in chemistry by bringing an odd shaped sheet of asbestos from work and sawing it into a more convenient square, using an electric sawing device in the garage. The clouds of dust were a marvel to inhale
