LINGAN, N.S. -- Nova Scotia Power says there was a hydrogen leak at its Lingan generating station.

Company spokeswoman Neera Ritcey says the leak occurred around 2 p.m. Monday in a storage area outside the plant.

Ritcey says an undetermined amount of the hydrogen, which is used in the plant's cooling system, vented from a tank into the air lowering the overall risk of combustion.

She says a safety crew from the plant as well as police and firefighters responded at the scene.

Ritcey says no one was hurt and the plant continued to operate although the immediate area of the leak was cleared of personnel.

She says the cause is under investigation.
