Examples include releasing flammable gas from a container interior, via through-passage gaps of a metal structure cylindrical flame barrier secured in a hole through a wall of the container, to an exterior region as released flammable gas, and combusting the released flammable gas in the exterior region. The cylindrical flame barrier extends a height, has an internal facing end that faces the container interior and has an external end that extends from top side of the wall to the other end, by an amount least a fifth of the cylindrical barrier's overall height. The external end absorbs combustion heat energy. The projecting portion radiates the absorbed heat energy. The radiating is determined in part by the projecting height, and is configured to maintain the interior facing end at a temperature below the combustion temperature of the gas.
