First you find out the depth of the concrete. Find a saw that will cut to that depth. If possible use electric, otherwise if your using a gas saw you should have a intake fan and a exhaust fan. A oxygen monitor is always a good idea, and do not work alone. Your concrete saw should have a water attachment to keep the dust down, if not then you can just spray the blade during cutting. Earplugs are also recommended.
