An ammonia leak at a Bama facility in Lier, Norway, has sent six people to the hospital and seven others to a local clinic for check-ups.

The incident occurred early Thursday morning, with emergency services responding to reports of a sharp smell in the industrial area.

Authorities have identified a ruptured pipe as the source of the leak, though the cause remains under investigation.

The affected building has been evacuated, and operations at the facility are temporarily halted.

Firefighters and industrial safety teams are working to contain the situation, with no immediate danger to the surrounding area due to calm weather conditions.

Ammonia exposure can cause severe respiratory and eye irritation, and in high concentrations, it can be life-threatening.

The incident highlights the risks associated with industrial chemical use and the importance of safety measures.
