CORNWALL – Workers at a Cornwall manufacturing plant were evacuated for a short time Thursday night after a natural gas leak.

Cornwall firefighters were called to Canadian Technical Tape (Cantech) at 1400 Rosemount Avenue around 10:30 p.m. for the smell of gas at the facility.

A portion of Rosemount Avenue was also closed to traffic briefly as a precaution.

Firefighters were able to shut off the valve to stop the flow of gas.

The scene was cleared by firefighters and the road reopened just before 11 p.m.

Enbridge Gas spokesman Andrea Stass says a regulator, which controls the pressure of the gas going into the building, malfunctioned.

“There is a safety check on that, it’s called a relief valve, so when the regulator…has an issue it will relieve the pressure. That was relieving the pressure and that’s why you could smell the gas,” she told Cornwall Newswatch.

Stass said the regulator has been repaired and the plant equipment has been turned back on.

The repair was finished by 3 a.m. Friday.
