Two more firecracker and pyrotechnics factories have been razed to the ground in a village here following a fire that started in one of the factories, causing damage estimated at P180,000, a police official said.

Chief Inspector Rosauro Francisco, Hinigaran police chief, said an explosion was heard at about 1 p.m. Tuesday at the factory of Conrado Juguan in Barangay (village) Tagda, Hinigaran, 60 kilometers south of here, causing the fire that spread quickly to the adjacent factory owned by Pablo Enrile.

No one was injured, said Francisco.

The incident took place more than a month after a pyrotechnics factory in another barangay in Hinigaran exploded, killing one person and causing injuries to another.

Francisco said a spark from potassium chlorate, a chemical used in the manufacture of pyrotechnics, had triggered the fire.

The residents and responding firefighters contained the fire after 30 minutes.

Francisco said Juguan and Enrile were among the licensed manufacturers of pyrotechnics and firecrackers in Hinigaran, the pyrotechnics capital of Negros Occidental province.
