CHON BURI: A fire caused extensive damage at a tube and condenser manufacturing factory in an industrial estate in Phan Thong district early on Monday morning.
At least 10 fire trucks were called in to fight the blaze, which was reported about 1am at a factory owned by SeAH Precision Metal (Thailand) Co Ltd in Amata Nakorn Industrial Estate, Thai media reported.
It took fire fighters about an hour to bring the flames under control. Investigators had yet to determine the cause or assess the damage done to the business.
Thanik Sichan, 49, an employee at the factory's warehouse, said he heard a loud explosion before the fire erupted, and quickly sounded the alarm.
He heard more explosions from time to time as the fire spread.
The fire started at a pond for leakage testing and spread to copper wire products, police said. There were no reports of injury.
SeAH Precision Metal produces compressor tubes and wire condensers for refrigeration systems and the automobile industry. It is part of the South Korea-based SeAH Group.
