An employee was on the first floor when he was called down to the basement level to assist with a repair. Coworkers had drained water from a boiler into a sump pit, which was approximately 3 feet deep and 2 feet in diameter. There was no cover on the pit, and the sump pump had trouble keeping up with the volume of water being added and quickly filled up. When the employee came down from the first floor to help, he fell into the sump pit and suffered second and third degree burns on his lower torso, legs, and hands. He was hospitalized.
