The workshop explosion in Kunshan on Saturday, which has claimed at least 75 lives and injured 185, was a major accident for which company leaders and local government should take responsibility, according to the investigation team.

The team, headed by Yang Dongliang, director of the State Administration of Work Safety, said company leaders neglected safety regulations.

Many workers at Kunshan Zhongrong Metal Products confirmed that the wheel-polishing workshop caught fire two months ago but no one paid attention as the fire was extinguished quickly.
