A toxic leak forced the evacuation of a factory in St. Jean sur Richelieu Tuesday night.
The workplace accident happened at the Thomas & Betts company at 100 Longtin St. around 11:30 p.m.
Alarms went off as soon as the hydrogen cyanide was released, and 100 people inside the building went outside without any injuries.
A Hazardous Materials crew was quick to ventilate the building, and make sure no pockets of the gas remained.
Hydrogen cyanide is normally a liquid, but boils at slightly above room temperature. It is commonly used in electroplating.
By 5 a.m. the hazmat team had given the all clear and people were allowed to return inside.
