I live in an old house and have a unique situation I’m not sure how best to handle. There is an underground room in my basement underneath the front porch that was originally used to store coal for the house’s furnace. It is a large room – probably about 15’ x 20’ with probably about a 15’ ceiling. It is extremely well built, appears to be dry but has probably not been touched for 70 years. Being underground, I have thought about cleaning it up and storing food, water, etc down there.
The thing is there is still a large amount of coal in the room. Spread evenly across the floor, it would probably be a pile about 2 feet tall. I was wondering if anybody here knows if there would be an advantages or disadvantages of leaving the coal there?
I have thought about disposing of it but also figured I could just install some kind of floating floor over top it, if there are any benefits of leaving it there. I know nothing about coal and have no idea if there are any positive reasons to keep it around like – I don’t know – moisture control, attract/repel bugs or rodents, etc. – or is the coal just a dirty health hazard?
