The titanium tetrachloride (TiCl) leaked from a distillation column at LyondellBasell on Meadow Road around 8:30 p.m., officials said. The situation was deemed under control around 10 p.m.
TiCl is a volatile liquid that forms opaque clouds of titanium dioxide and hydrated hydrogen chloride after making contact with humid air.
“The leak involved a product used as a catalyst for the production of plastic,” a company spokeswoman said.
"The leak is isolated and contained, and no one was injured as a result of this incident."
The facility is equipped with a state-of-the-art leak detection system, which deployed water immediately, the spokeswoman said.
