I've just found out that old vinyl tiles can ontain asbestos & shouldn't be moved or damaged.Several months ago I started removing the vinyl tiles on our bathroom floor & had to break them up to remove them.A few bits proved hard to budge,so are still stuck down.Now I'm terrified that I've exposed the whole family to asbestos.I didn't take any precautions regarding dust ect,as I'd no idea that tiles could contain anything dangerous.Now I don't know what to do,I just feel sick & shaky.What do I do now-if there is any damage,it is already done.
