"At around 1:40 pm (GMT 5:40 am) on January 14, the Zhuhai Changlian Petrochemical Co., Ltd. in Gaolanguang District caught on fire," the Zhuhai Emergency Management Bureau said in a statement on its official Weibo account.
According to the statement, the fire had already been put out and no casualties had been discovered on the scene.
The authorities have already launched an investigation into the cause of the incident.
The recent blast is the latest in the string of industrial accidents that have rocked China in recent years. In March, a major explosion at a chemical plant in eastern China killed 78 people and prompted authorities to step up security measures around the country.
