"LITTLE ROCK, Ark. -- An empty gasoline tank undergoing repairs exploded Tuesday at a fuel storage facility in rural north-central Arkansas, killing three workers, authorities said.
The tank had been previously cleaned and workers had entered it to prepare to install new equipment when the blast occurred just before 2:30 p.m., said Rick Rainey, spokesman for the facility's owner, Houston-based energy company TEPPCO Partners LP."
