3 dead, 17 hurt in work site mishap INSIDE JoongAng Daily
An investigation by police there showed that heavy granite tiles removed from the outer walls of the building had been stored on the scaffolding instead of being carted away.
An official at the Bucheon Labor Office said that the workers did not remove the tiles using an elevator installed on the scaffolding for that purpose, and had piled up the tiles until the scaffolding gave way under their weight.
'They violated the safety rules by piling up material on the framework,' the labor office official said. He added that an investigation is under way to determine whether the scaffolding was installed incorrectly.
