According to US-based media reports, ExxonMobil said it was conducting air quality monitoring at the site on Wednesday and was cooperating with regulatory agencies.
According to ABC News, the Olefins plant is part of the company's 3,400-acre refinery complex in Baytown. Wednesday's fire is reportedly only the latest to have taken place at the Houston-area petrochemical facilities this year, including another at the ExxonMobil Baytown complex.
