In addition, of the two workers from with Big Valley Labor Inc., there was a ranch foreman, representing the ranch management company; Bavaro Inc., on the jobsite. Employee #2 was grinding on the tank with a wire cup brush to clean it up. After Employee #2 finished, Employee #1 approached the tank with an oxy-acetylene torch to braze some small holes.
