A “dangerous chemical leak” from a train car in Ohio prompted evacuations and a hazmat response. “Numerous emergency and Hazmat crews are currently on the scene in Whitewater, Ohio, after an immediate evacuation order was issued following a train car leak of toxic chemicals, including styrene. Styrene is a colorless, flammable liquid with a sweet odor and is highly volatile. It is widely used in the production of plastics and rubber, which are essential for manufacturing products such as insulation, pipes, automobile parts, printing cartridges, food containers, and carpet backing,” Rawsalerts wrote. Officials have issued a warning residents to immediately go indoors and stay inside until further notice Close and seal doors and windows, close fireplace dampers, and turn off heat. This situation is still developing,” the post added. #BREAKING: Numerous hazmat crews are on the scene following the immediate evacuation orders due to a dangerous toxic chemical leak from a rail car⁰⁰#Whitewater | #Ohio Numerous emergency and Hazmat crews are currently on the scene in Whitewater, Ohio, after an immediate… pic.twitter.com/sp09o2cFyq — R A W S A L E R T S (@rawsalerts) September 24, 2024 WLWT 5 reports: This is happening near State Route 128 and U.S. 50, near the Great Miami River in western Hamilton County. Hamilton County EMA states that per Whitewater Fire officials, a “dangerous chemical leak” has occurred near State Route 128 and U.S. 50. EMA officials say the leak is not from a train derailment but a train car that has a valve open, releasing styrene gas. Here’s what we know. Mike Siefke, Chief of the Little Miami Joint Fire & Rescue District, said crews are working to contain the vapor by cooling down the affected areas. He said they have identified that there is issue where it’s releasing out of pressure relief valve. The fire department has issued an evacuation for those within a half-mile radius of the railyard by U.S. 50 and State Route 128 and a shelter in place for those within a three-quarter mile radius until further notice. Officials said Hamilton County EMA will be sending alerts to residents within a two-mile radius of the chemical leak.

A spokesperson for the Central Railroad of Indiana said the company was notified at around 1 p.m. Tuesday that one of its tanker cars was venting styrene near the intersection of US-50 and OH-128. Crews responded to the scene and began applying water to the tanker car. After several hours, officials said the car was safely separated from the rest of the train and the leak stopped. Still, officials said crews remain working on the car and testing the air. Local evacuation and shelter-in-place orders remain intact. “It’s not going to be short,” officials said of the current timeline. The Hamilton County Emergency Management Agency said those within a half-mile radius of the railyard by US-50, OH-128 and Valley Junction Road should remain out of the area until they receive an all-clear. Residents outside the immediate half-mile radius but still within three-quarters of a mile of the leak are told to continue to shelter in place.
