When I was younger, at the Montgomery County, MD County Fair. The Department of Fire Rescue Services set up a smoke maze and now I am an explorer at a fire department in Ohio and they were looking for ideas for our upcoming open house. Does anyone have any information on this, as I remember it, it was just plywood or osb and 2 by 4s made into a large maze. If anyone has any information on something like this or any other prevention ideas for our open house please post here.
