Ho Chi Minh City police have sought criminal charges against the owner of a fertilizer factory which exploded killing three people last year.
Huynh Van Hai was accused of workplace safety and hygiene violations that endangered a thickly populated residential area.
His 430-square-meter factory in District 12 saw a massive blast on October 17 afternoon, which killed three women workers aged 19, 30, and 36.
The workers were mixing chemicals by hand and using the heat from a small gas stove to pull plastic sheeting over bottles of the chemicals.
The disaster happened when a number of volatile ingredients, 320 kilograms of potassium nitrate, 25 kg of potassium chlorate, and 150 kg of carbonyl diamide, caught fire.
Described by police as an “especially serious incident,” the blast also injured five people in the neighborhood, destroyed seven houses and damaged many others.
Police said Hai was using dangerous chemicals without a safe storage place, and failed to train his workers in safety protocols or provide them with proper protection.
If charged and convicted, he faces up to 12 years in jail.
