It is 10-15% Chrysotile - white asbestos - you breath dozens of
fibres of it every day. The only recorded harm caused by Chrysotile
is amongst those who have worked in atmospheres laden with it for
decades.
Slightly contradicts what I've read elsewhere...


an air hammer, power tools are also a no-no. Looks like I'll either be
removing it by pushing it from the inside, or spending a looooong time
removing the roofing nails they've secured it with :-(

If you do the latter you would certainly be exposing yourself to the
greatest, and well known, risk of asbestos cement. Old asbestos
cement sheets are very fragile and a number of people have been
killed falling through them.

Hmm, well seeing as at worst I'd only be falling through a wall (the
sheets are on a sheltered wall that butts up to a garden fence), I'm
feeling pretty sure that I'm safe as far as this goes. You're right
about them being fragile, I pulled off a piece last night with my hands.
