Sire, go easy on the Proust please!
And—do I read correctly, somebody wants to barge into an asbestos-riddled building just for some photographs?
Do you know that just brief exposure to stirred asbestos dust can have profoundly serious consequences? How does acute asbestiosis sound?
In Australia, people have died from this poisoning from both very long and very short exposure. So I can only repeat what others have said and that is to respect the legal standing of the building's current state and stay well away from asbestos. It is a death wish.
