FRANKFURT (Reuters) - At least one person died and six people were injured on Monday by an explosion and subsequent fire at chemicals maker BASF's biggest production site in Germany, the company said at a news conference.
In addition, six people are still missing, the Ludwigshafen site's chief, Uwe Liebelt, told journalists.
The explosion occurred on a supply line connecting a harbour and a tank depot on the site at around 1130 local time (0930 GMT), BASF said, adding it could not yet say what caused the explosion.
A fire that broke out following the blast sent up plumes of smoke, prompting BASF, the world's biggest chemicals company, and the city of Ludwigshafen to urge residents in the surrounding area to avoid going outside and to keep their windows and doors shut.
Measurements taken in the area so far have indicated no risk from toxic fumes, BASF said.
"We will of course do everything we can to clear the matter up," site chief Liebelt said.
BASF said it turned off 14 facilities near the blast site for safety reasons, including its two steam crackers, large units that make important basic chemical components. Liebelt said he could not yet comment on how much financial damage the explosion would cause the company.
The Ludwigshafen site, around 80 kilometres (50 miles) south of Frankfurt, is the world's largest chemical complex, covering an area of 10 square kilometres (four square miles) and employing 39,000 workers, according to BASF.
The harbour at which the explosion occurred is a terminal for combustible fluids such as naphtha and methanol that are important for BASF's supply of raw materials.
News of the explosion came less than two hours after BASF said four people were injured in a gas explosion at its Lampertheim facility, a plant near Ludwigshafen that makes additives for plastics.
