Safety guy question: chemical fumes

[JollyRoger]

Ok, I have to varnish about 600 sq ft of floor in my house with oil-based polyurethane, in rooms that will be sealed in plastic in order to keep dust off the varnish. Needless to say, it's going to get pretty stinky in there. Can a cartridge element-type respirator be used, or do I have to go with some sort of air supply? If an air supply is used, does anyone make a kit that fits onto a shop air compressor ? Any advice is appreciated!
