Vichien Emprasertsuk, senior vice president of Toyota Motor Thailand, said that despite the fire, the Ban Pho facility is operating as usual.
"The incident does not affect the production or the supply of parts to our dealers," he said.
At the facility in Chachoengsao, Toyota is churning out 220,000 units per annum, one third of its combined capacity of 650,000 in Thailand. It is the main production site for Hilux Vigo.
The fire broke out on Sunday at the engine oil storage warehouse, which is estimated to cost Bt50 million in initial damage.
The fire was put out before midnight of the same day, entirely by water. No chemicals or foam were used, the company said in a statement. All the water used in the process would be recycled. Toyota has also worked with government units in Chachoengsao, to evaluate the impact of this incident on the nearby community.
