The whole thing with fumes and galvanized trash cans comes up when people do things like burn leaves in them, or worse try to barbecue in them. At "normal" temperatures they're safer than plastic trash cans which incidentally emit fumes even at room temperature.
Oh, and one of our neighbors tried burning leaves in a
plastic trash can. :shakehead If you think galvanized trash cans emit fumes when hot, well, they ain't got nothing on plastic ones! The fire department had to come to extinguish that mess. It stunk up the entire few surrounding blocks for quite a while.
