On board ship, many tanks only have a bolted down manhole cover on deck, as means of access.
Especially in tropics, it can be a real oven inside those tanks.
Also, we usually don't know how long since the last time tank was opened, and if there is sufficient oxygen in the air to support life.
You can test with a flame safety lamp. sufficient O2 to sustain a flame, will sustain life.
but normally, we just drop an air hose in the tank, with a valve on the end.
The valve is just opened so there is a weep of air coming from it.
In half an hour, the tank is cool and the air fresh.
The MASH tents had pockets sewn into the side walls, held an aluminum venturi, size of a garden hose nozzle.
An engine powered rubber tired air compressor was parked remote from the tents, and compressed air fed to the venturis via large air hoses hooked to manifolds with a dozen smaller air hoses hooked from the manifolds to tent venturis.
Dropped temperature inside by 15 to 20 degrees.
Injured soldiers healed quicker when comfortable.
