Anyhow (fellow scientist :), how do you know you were looking at the
actuall "killer" fibres themselves?....

because the family business spent 20 years hauling the stuff around
(fireproof flooring and panelling) and I know what the fibres look
like under a microscope. I have 2000 sq ft of asbestos cement roofing
board (20 years old and 50+ years old) above the sheds, and it's best
not to ask what I've got squirrelled away inside them, but I can tell
you that I'm not worried about it catching alight...

The issue is really down to what happens when the squirreled away stuff
catches fire and the roof scatters itself downwind due to steam
*exploding* the cement fibre.

Elfin safety field day!

Whenever the opportunity has arisen, I have replaced my big six roofing
with the post 1995 version or insulated steel sandwich.

Currently down to one small shed and the roof over a timber store.

For employers, the control of asbestos at work regulations 2002 imposes
a duty to manage the stuff in non domestic premises.

I have a plan:-)
