UPDATE: ExxonMobil says passersby may notice flaring at its Baton Rouge refinery Thursday. The flaring is part of normal operations and is no cause for alarm, ExxonMobil said.

You may notice flaring at our facilities as we work to adjust operations. Flares are safety control devices intended to consume excess hydrocarbons. We apologize for any inconvenience this flaring may cause.

BATON ROUGE - A large fireball erupted within the Exxon refinery in north Baton Rouge late Tuesday night, and as of 6:45 a.m. Wednesday the blaze was completely extinguished.

Shortly after the fire broke out, the Baton Rouge Fire Department was on the scene, arriving just after midnight. Exxon posted on Twitter that its fire crew had the blaze contained to the area where it occurred.

There were no injuries, and specific information related to the cause of the fire has not been released. 

The Baton Rouge Fire Department said there was no off-site impact, but officials are continuing to monitor the facility fence line and surrounding areas of the North Baton Rouge community. They say at this point, "all readings are non-detect" but they're continuing to conduct air monitoring.

Officials plan to launch a thorough investigation into the incident to find out exactly what caused the fire. 

East Baton Rouge Parish Mayor-President Sharon Weston Broome praised first responders for their swift response to the incident.

Good job to our first responders for their response to the fire at ExxonMobil overnight. I’m thankful there were no injuries and Baton Rouge Fire Department determined there was no offsite impact to air quality.
