Oilspill on aircraftcarriers

The Navy used to have plenty of radial-pistonengined aircraft on
carriers.
Now my question: in radial-engines oil is collecting in the lower
cylinders when its stopped. Thats is one reason to handturn the engine
before it is started.Then the oil is queezed out in the exhaustsystem
and eventually on the ground.
Now i thought how dangerous, filthy and slippery the deck must have been
when an deckload of Hellcats, Avengers and so on started there engines
nearly simultaniusly.
How was this avoided or was it just ignored.
