Fire in built environment

A major fire broke out at a thinner and flammable chemical factory in Ban Pho district on 6 March 2026, sending thick black smoke into the sky and triggering repeated explosions, authorities said.
The blaze began around 16:00 at Cargo Chemical Co., Ltd., located at 79/1 Moo 4, Thep Ratcha subdistrict, Ban Pho district. Officials said the fire quickly intensified to a severe level, with flames and dense smoke visible from a distance.
Witnesses reported hearing multiple loud blasts from inside the facility, complicating firefighting efforts. Authorities said some workers were believed to be trapped inside Building 2, but rescue teams had not yet been able to reach them due to intense heat and rapidly spreading flames.
A local resident, Yupin Sapmool, 48, said she heard a loud explosion at around 16:00 while staying with relatives and her nephew nearby.
“I heard a huge bang and saw flames spreading quickly, so we rushed out of the house in panic,” she said.
Firefighters and water trucks from nearby districts have been deployed to contain the blaze. Crews are focusing on cooling surrounding structures to prevent the fire from spreading to adjacent buildings.
Authorities have urged residents to avoid roads near the site to allow emergency vehicles to operate.
The cause of the fire and the extent of the damage will be investigated after the blaze is brought under control. Officials said updates would be provided as the situation develops.
