A punctured chemical tank car leaked hydrofluoric acid that formed a large, slow-moving cloud of acid fumes at treetop level early today, and residents of a two-square-mile area were evacuated, officials said.

No one was injured in the incident on the city’s southwest side and the cloud did not pose an immediate threat, Mayor James P. Perron said. Residents, who were evacuated around 7:30 a.m. in zero-degree weather, remained out of their homes into the afternoon as officials conducted air quality tests.
