Employees evacuated after chemical leak in Falls

NIAGARA FALLS – City police and firefighters responded to a chlorine leak just before 9:30 a.m. today at Tier Holding, a facility that uses caustic materials to clean and scrubs tank cars for chemical companies.

According to the Niagara Falls Fire Department a plume of smoke, later identified as the chemical titanium tetrachloride, was released into the air, affecting some employees on the site at 33 South Hyde Park Boulevard. Both Tier Holding and nearby businesses were temporarily evacuated.

The caustic material used for scrubbing had reportedly reacted with a chemical in the tank causing the titanium tetrachloride to be released. The release was identified as a “small leak” that did not register on monitoring meters, according to the Niagara Falls Fire Department, and the site was determined to be under control at 9:47 a.m.

About 10 employees took their own vehicles to a local hospital to be checked.
