China, the world’s second-largest economy, has a history of workplace disasters. Workers are often poorly trained or ill-equipped to protect themselves from industrial accidents.
A fire at a poultry slaughterhouse in the northeastern province of Jilin in June 2013 killed 120 people. The blaze was blamed on poor management, lack of government oversight and locked or blocked exits. -Reuters
