I was in a church (built 100+ years ago) and noticed that a bit of the ceiling had crumbled onto a table. I brushed it aside without a thought, and only then it dawned on me that it may contain asbestos. I washed my hands post-haste. Should I take further precautions?
Here's a photo of some of it: https://i.imgur.com/v4h9ulo.jpg
Do you wager it's asbestos?
