A woman died and 25 people were injured, three seriously, after a fire broke out at a lightning-rod factory yesterday morning.
"I heard a popping sound before I saw sparks that quickly spread around," said Chalong Khaemadan, a 35-year-old maintenance official at KML Technology Company.
The factory spans about 2 rai (3,200 square metres) in Nonthaburi's Bang Yai district. There were about 60 workers inside the factory building that caught fire.
It took firemen about 30 minutes to extinguish the blaze.
Killed in the accident was Wannapa Srisuk, 30. Her body was found under a large chunk of the roof that fell down during the fire.
"Because of the falling structure, many workers were injured," Chalong said.
He and several other colleagues helped the injured out of the fire-engulfed building.
The company's manufacturing manager Preecha Panasuwan provided similar information.
"I heard some kind of explosion," he said.
Police have collected evidence at the factory, but further examination is needed before the cause of the fire can be determined.
Nonthaburi disaster prevention and mitigation chief Ekkaphop Janpen said most of the injured had been allowed to go home after receiving treatment.
"Five remain in hospital," he said.
In intensive-care units are Komsan Ornra, 35, Wanpen Luang-aram, 40, and Panita Charoensap, 25.
They suffered burns to large parts of their bodies.
