Authorities say 6 people who were helping clean up UCLA's flooded Pauley Pavilion are being treated for exposure to carbon monoxide. A worker begins the task of cleaning up at least an inch of water covering the playing floor at Pauley Pavilion, home of UCLA basketball, after a broken 30-inch water main under nearby Sunset Boulevard caused flooding that inundated several areas of the UCLA campus in the Westwood section of Los Angeles on Tuesday, July 29, 2014. Worker Ruben Monter mops up the floor at Pauley Pavillion Wednesday July 30, 2014 in Los Angeles.
