No injuries were reported following a May 19 fire at a compounding plant operated by RTP Co. in Ladenburg, Germany.
The fire broke out just before 11 a.m. local time, according to a report in newspaper Die Rheinpfalz. Firefighters were still working to extinguish the fire as of 4 p.m. local time.
According to the report, 13 employees were on site at the time. All were able to leave safely.
No cause of the fire was identified in the report, but investigators weren't yet able to enter the building. The report said that 150 firefighters from local communities responded to the fire.
Firefighters were able to stop the fire from spreading to a neighboring building. The area around the plant was cordoned off.
The fire caused a large amount of smoke in the area. Air measurements by the fire department showed that there was no danger to people and the environment from the smoke, the report said.
Officials with RTP in Winona, Minn., declined to comment. In Ladenburg, the firm makes compounds based on engineering resins, with a focus on very long fiber and conductive compounds.
The 110,000-square-foot Ladenburg plant opened in 2011 and was expanded in 2012.
