Early this morning, Torrance Fire crews responded to a flaring event at the Torrance Refinery.

Around 6 a.m., Torrance Fire officials responded to the Torrance Refining Company due to a report of a unplanned, visible flaring event. The flaring lasted a couple of hours and officials say it was because of a unit upset. There was no offsite impact and there were no evacuations.

A flare is a tall stack equipped with burners used as a safety device. They are used for the combustion and disposal of combustible gases due to emergency relief, over pressure, process upsets, startups, shutdowns and other operational safety reasons.

Last night, around 6 p.m. there also was a report of a flaring event.
