One thing does surprise me. There are surely hundreds, possibly more than a thousand, of these Okal things. And people live in them without dropping dead. Whether this particular one, so extremely contaminated, which was under duress and practically auctioned off as a demolition object, was made worse afterward by the owner? How often in the past did DIY enthusiasts also paint Xylamon inside on wood panels! How thoughtlessly were wooden windows also coated inside with protective glazes meant for outside. Real Carbolineum was even used for attic boards. All that was completely freely sold in my early years. We made Carbolineum ourselves from old oil and thereby made fence posts permanently durable, painted boat docks at low tide, what passed was taken by the next flood....Who ever read what was on the cans and canisters.
