Two construction workers were killed on the spot Tuesday after the scaffolding they were standing on collapsed in the northern province of Thanh Hoa.
Four labourers were working on the fourth story of a house being built when a pole in the scaffolding broke at around 8 a.m. Three of them fell while the fourth grasped on to a pole at his side and escaped unhurt.
Le Huu Du, 46 and Nguyen Van Minh, 45 were killed while Nguyen Ba Hung, 39, was rushed to hospital with severe injuries.
The three workers were standing at one end of the scaffolding with a bucket of mortar, which proved to be heavy enough to break the supporting pole on their side, said Le Van Hung, 40, who was unhurt.
Hung said he was standing alone on the other end of the scaffolding and was able to grasp the cane on his side.
Police in Thanh Hoa are investigating the accident.
