There is a strong odor in my basement, and it's getting worse. I can't tell where it's coming from, but it smells very similar to when you burn a pan on the stove or the handle of a pan. It's does seem like a burning kind of smell. I am worried it's electrical, or maybe the furnace. I don't know who to call or what to do. It smells awful, and it's hard to be in the basement because of it. It's seeping up to the main floor near where the basement door is. What are some things to check out? Is it potentially dangerous? I have two kids.
