Was filtering the fryers at Burger King for the first time by myself. When I was putting the filtered grease back in I turned the fryer on before it reached the heating coil which caused it to smoke. Instead of turning it off(which would of fixed the problem) I panicked and pulled the fire suppression box on the wall. Foam shot out of these two tubes above the fryer and spread over the kitchen. We had to close down at 2pm and clean EVERYTHING before the fire inspector cleared us. Fortunately I didn't get in trouble since the Crew Trainer didn't go through the proper procedures with me. The coworkers who had to stay in clean with me wasn't too happy with me, but I deserved all the hate that came my way.
