A large explosion at an oil refinery near the Texas coast on Monday shot plumes of smoke into the air and forced nearby residents to shelter in place, officials said.

No one was injured in the explosion at the Valero refinery in Port Arthur, about 90 miles (145 kilometers) east of Houston, Mayor Charlotte M. Moses said. She urged residents in parts of the west side of the city to stay put, saying firefighters had arrived.

This is yet another explosion at a refinery which uses massive amounts of HF, the 4th in less than 12 years. If you want to help prevent another disaster, follow the NRDC Lawsuit status to remove the HF threat.
