I have seen 5 fires from rags.....including a good portion of a convent that burned down in Santa Rosa... a roof fire at 115 Sansome Street in the fog at 60 degrees, and in an alley in China Town near St Marys Church in a dumpster in the rain.
Leaving rags laying around on a job-site was a good way to get fired, and I mean by the General Contractor not the Painting Contractor.
Put some paint thinner on a rag, and put that in your back pocket for 5 minutes...enjoy the (minor) chemical burn. For years, THAT was a favorite "joke" among journeyman.....tell the new apprentice to make sure he kept a thinner rag in his back overalls pocket, so he would be ready to clean up any Drips/Drops/Over-spray.
I can assure you, "rags" is the Real McCoy.
That convent fire put a nun in the hospital, and then plastic surgery, and helped to close the doors of one of our older painting contractors.
