PHNOM PENH, April 8 (Xinhua) -- Two people were killed and four others injured after a steam generator at a garment factory exploded on Saturday in southwestern Phnom Penh, a local police officer said.

 

Hem Pheary, deputy police chief of Stung Meanchey commune, said the incident occurred at 11:50 a.m. local time when the workers took a lunch break.

 

"One security guard and one cleaner were killed and four other workers got wounded in the explosion," he told Xinhua.

An investigation is underway to find out the cause of the blast as the factory's owner was detained for questioning, he said.

 

"We are investigating the cause of the explosion, but it might be caused by the intense heat of the steam generator," he said.

It was the second incident in a fortnight. On March 22, a steam boiler at a garment factory in western Phnom Penh exploded, leaving one woman dead and seven others injured.

No maintenance is the usual cause. maybe a very cheap installation. If the boiler is installed correctly they can never explode, especially these days. Most small factory steam boilers in western countries are automatic, a few checks and switch on. Any problem they will auto shut down.
