And don't forget the chemical burns to our exposed skin thanks to the 'carbonic acid' we wash the windows with!
Oh, and all those window cleaners fried every year when there carbon poles touch overhead cables....
Actually, the asbestos thing always worries me a little, when I was working for my family's building company back in the 70's, on some sites, working around asbestos was common, and the dangers were not known at the time.
It can take 30 years before asbestosis bites you in the backside, and some of the guys I worked with have either died from it or have it..all older than myself I might add...but still, gives me pause for thought when I see those ads...
