For the second time in five days, Cambodia’s garment industry has been rocked by another partial collapse of a structure at a factory.

Garment workers are reporting that at least 10 people, including a pregnant woman, have been injured after a concrete platform collapsed into a pond at the back of the Top World Garment (Cambodia) Ltd. factory on the outskirts of Phnom Penh at about midday today.

Workers told the Post they still believed people were in the pond. An official for the coalition of Cambodian Apparel Workers’ Democratic Union (C.CAWDU) said that as many as 20 people might have been sent to hospital.

“I was standing on the end of the kiosk. I saw it begin to collapse and people falling into the water. Five other people and myself helped pull a pregnant woman from the water,” Top World Garment factory employee In Srey Nin said.

Members of the Prime Minister’s Bodyguard Unit and police are searching in the pond for more survivors.

So far, there have been no confirmed casualties.

Attempts to reach a company representative via phone were unsuccessful.

Two people died on Thursday when a mezzanine floor collapsed at the Wing Star Shoes Co., Ltd factory in Kampong Speu province.

Both factories are members of the Garment Manufacturers Association in Cambodia. GMAC secretary-general Ken Loo said he did not yet have any details.
