vented box for Honda 2200 generator

Texaco dealer in Athens, Ga in the early 70's. Truck was unloading one summer night into a bulk tank at the distributorship. Humidity was high and air was still. In one of the buildings at the distributorship was a waterheater with a gas pilot light. As the hollow where the plant was located filled with fumes, they reached the pilot light and the whole area blew up. We heard the explosion from 15 miles to the north. Windows were blown our of many of the businesses in downtown from the concussion. The public housing across the street and up on the hill had a building that had to be torn down because it lifted second floor off the walls. The driver was badly burned but not killed. Every fire dept in the area sent trucks to help contain the fire. It burned all night and into the next day.
Fumes will explode. I was there helping evacuate the folks in the housing apts.

Again, stories that are not relevant...I doubt the OP is operating a bulk carrier truck and if it's bottom vented it won't pool like in a hollow. Again, bottom or side vented won't make much difference anyway.

I'm sorry you are a little slow on the uptake. I thought my point was pretty clear - gasoline fumes will explode. Hard to understand? denying it does not make it untrue

Horsedoc - Exploding fumes.
The city where I was employed as a F/F for 30 years had a bulk plant.
One evening, a trucker was fueling his double tanker with gasoline. Went to chat with the security guard in the guard shack.

The overflow protection failed, major spill on the ground. He had left the engine running on his (diesel) tractor. The engine began to "run away" when it picked up the fumes.

He made a futile (and fatal) attempt to run back and shut off the engine. It went "boom" big time. Second big time boom when the second tank of the double failed. F/F was on a (foam) deck monitor for the 2nd one - said he left "claw marks" in the diamond plate on top of the apparatus due to the heat wave.

The tank/s failure: It's called a "BLEVE" - Boiling Liquid Expanding Vapor Explosion.
AFFF did it's job - but not fast enough to stop the 2nd explosion.

No structures nearby.

Not slow at all...your story is simply not relevant to the situation described.

"Can" not "will" and only under very specific conditions that are incredibly unlikely given the OPs proposed setup.

Wildly different from a truck dumping 5000gal in a low area on a calm night.

I suppose you refuse to own a gasoline vehicle because they blow up all the time too?

Did we ever go South on this one?
