More than 100 workers, including three Japanese, were injured and at least three were missing in a fire that hit a huge factory south of Manila and sent thousands of employees running to safety, an official said Thursday.

The fire at the House Technology Industries was under control but has not been fully extinguished nearly 18 hours after it started in General Trias town in Cavite province south of Manila, said Governor Jesus Crispin Remulla. Firefighters were hoping to enter and inspect the factory later Thursday.

About 10 of the injured were in critical condition, Remulla told ABS-CBN TV news, adding some employees jumped from windows to escape the blaze at the three-story building where pre-fabricated house parts are manufactured for export to Japan.

The fire apparently started in a section where a machine used to manufacture house insulation materials overheated, he said.

A third of about 15,000 employees were on duty when the fire struck and company officials were doing a count to find out if any more were missing at the sprawling factory compound located in a special economic zone in General Trias, 26 kilometers south of Manila.

In 2015, a fire that rapidly spread in a rubber slipper factory in a northern Manila suburb killed 72 people, prompting then President Benigno Aquino III to order a thorough inspection of some 300,000 factories in metropolitan Manila alone. He ordered charges to be filed against the owners of the Kentex Manufacturing Corp and local officials, who he said ignored the factory's failure to meet safety requirements.

The Kentex fire was one of the worst in the country after a 1996 disco blaze that killed 162 people in Manila.
