Chemical Leak Triggers Shelter-in-Place Order in N.J.

The incident created a visible cloud.

On Sunday, a chemical leak in Edison, N.J., prompted authorities to tell residents to stay indoors.

The leak was reported at the LyondellBasell plant that makes polypropylene plastic resins. According to, a catalyst used in plastic production leaked and created a cloud above the site.

Locals were told to stay inside, close their windows and turn off their air conditioners. 

According to the company, the plant's leak detection and deluge system caught the distillation column leak immediately. Water was deployed and it was isolated. 

The company's on-site incident response team was immediately activated. 

While the incident created a visible cloud, no injuries have been reported. 

On Monday morning, the shelter-in-place order was lifted, windows were opened, and AC units were restarted -- which was important when the forecast calls for temperatures reaching 90 degrees. 

LyondellBasell is one of the largest plastics, chemicals and refining companies in the world. The company sells products into more than 100 countries and is the world's largest producer of polypropylene compounds and the largest licensor of polyolefin technologies.
