All-clear at site of Ulster hydrogen leak scare

Employees were evacuated, CSX freight rail lines were stopped and the Ulster Hose Company was called in but, when all was said and done, there was no hydrogen leak at the Precision Flow building in the town of Ulster today.

Sam Appa, chief of the Ulster Hose Fire Company, said his department was notified at 10:30 a.m. about the possible leak in Precision Flow’s building at TechCity, the former IBM-Kingston site. He said firefighters did not initially know whether the suspected leak was inside or outside the building and had to use extreme caution because hydrogen, in its liquid form, is highly flammable and combustible.

A faulty sensor may be at fault in the scare at the plant.
