In the recent Texas appellate case of In re Wyatt Field Service Company, the court considered whether a new trial was warranted in connection with two plaintiffs’ serious personal injuries that arose from a refinery accident. At the refinery, crude oil is turned into gasoline. Tar is a byproduct of the process. The tar is broken down into pure carbon by a flexicoker unit. The carbon is called “coke.” The coke is heated and returned as a source of heat for the reactor.
Exxon Mobil performs maintenance on the flexicoker unit every two or three years. As part of the process, the heater has to be cooled down through spray from nozzles. The coke builds up in the nozzles and clogs them. The spray nozzles are replaced with dummy nozzles. The worker must pull the dummy nozzle out, and an Exxon Mobil employee closes the gate valve to keep steam and coke inside. Two employees of LWL, Inc. were removing the dummy nozzles in 2011, when one came out too far and the gate was not shut. Coke and steam were sprayed on them, causing burn injuries.
