Locals, living near the city's Griesheim industrial park, have been urged to keep doors and windows closed. As a precautionary warning, sirens were triggered in Griesheim and in neighbouring Nied district, a police spokesman said.
Early in the morning, a lorry loaded with a liquid chemical had toppled over. The fire brigade reported on its website that hydrochloric acid fumes had started leaking from a container.

According to the city's fire service, the situation in the area is currently being assessed as stable, with the latest air measurements recorded as normal.
Hydrochloric acid is of wide industrial use and must be handled with appropriate safety precautions because it is a highly corrosive liquid.
