Photos by local media show white fog-like gas shrouding what appear to be factory grounds. Local authorities said no ammonia was detected in the air nearly three hours after the leak.
Workplace safety hazards abound in China. In August, a hazmat warehouse caught fire and exploded in the northern port city of Tianjin, killing 165 and leaving 8 missing.
