The leak occurred at 8:40 a.m Wednesday. when a truck carrying 30 tonnes of liquid ammonia was unloading at the factory of Chifeng Pharmaceutical Group, but was sealed in about 50 minutes, the Hongshan district government said.

A pipe suddenly burst during the unloading. No one died in the leak, according to the government.

The 246 people are workers in the factory, emergency responders and residents living nearby.

An initial investigation suggested that the leak was caused by workers failing to operate the equipment properly and old pipes.
