VIDEO: A man working atop the iconic Fresno State water tower had to be rushed to the hospital today after being overcome with heat, eventually going into cardiac arrest. "The extended work period up on top there, the strenuous work that they were doing with the heat and the high humidity today, it just overcame him," said Battalion Chief Mike Gibson of the Fresno Fire Department. The man was one of three divers who were scheduled to do maintenance work on the inside of the water tower on the Fresno State campus. Fresno Fire says he had a pulse and was breathing in the ambulance on the way to Saint Agnes Hospital. According to the Fresno Fire Department, rescue crews had to remove the other two workers from the tower as they were not in a condition to make the 130 ft. climb down on their own. Those two workers were not transported to the hospital. Fresno Fire says extra personnel were called in to prevent their own crews from heat exhaustion
