And by "close by" I mean the vacuum cleaner running and the hose nozzle clamped or taped right next to the cutting tool to suck up the mess as it comes off the cutter. The air flow helps to cool things a bit at the same time.
I also recommend wearing a face mask when cutting a lot of cast iron. When you start blowing black goo out of your nose you'll understand all that powdered graphite is NOT your friend.
