Chemours plant in Dordrecht releases about 45 kg of hazardous substance overnight

A hazardous gas leak occurred at the Chemours facility in Dordrecht late Monday night into Tuesday, releasing approximately 45 kilograms of tetrafluoroethylene, a substance classified as a Very Persistent and Very Hazardous Substance (ZZS). The leak was caused by the rupture of a pressure-relief plate, which protects the pipeline carrying the chemical. The leak happened under normal operating conditions at the company’s FEB plant.

In response, Chemours immediately shut down the affected pipeline, and efforts are underway to investigate the cause of the incident. A new pressure-relief plate will be installed, and the company plans to carry out further investigations throughout the day. According to a statement from the company, the leak was brief, and the cause has not yet been definitively determined.

The environmental watchdog, DCMR, has not dispatched a team to the site, as the emission took place quickly, and the cause remains undetermined. DCMR has requested Chemours to provide an update on the situation by 3:00 PM on Tuesday, including a report on the cause of the leak.

Tetrafluoroethylene

Despite the brevity of the emission, the release of tetrafluoroethylene is a serious concern due to its potential health impacts. Tetrafluoroethylene is a colorless, odorless gas used in the production of several products, including Teflon. While its immediate health effects can include dizziness, headaches, visual disturbances, suffocation, and loss of consciousness, prolonged exposure can lead to more severe health consequences.

Exposure to tetrafluoroethylene can have significant short-term effects on human health. Increased exposure can lead to symptoms such as dizziness, headaches, vision issues, suffocation, and a loss of consciousness. Prolonged exposure is more concerning, as research has shown that tetrafluoroethylene is a potential carcinogen.

According to a 1997 study by the U.S. National Toxicology Program, animal testing indicated that exposure to tetrafluoroethylene can lead to the development of benign and malignant tumors in mice and rats. These tumors were found in the liver and blood vessels of the liver. Additionally, there was an increased likelihood of kidney tumors and cases of leukemia in female rats. Mice of both sexes also exhibited cancers in their immune systems in various organs and tissues. The substance is therefore deemed "reasonably anticipated" to be carcinogenic to humans.
