During the evening of July 19, 2021, a heat sensor was triggered twice, activating the fire alarm both times. As per Ottawa Fire Services practices, a fire truck was dispatched both times and Ottawa Fire Services confirmed false alarms. Investigation indicated a false alarm both times due to increased operation of machinery in the room and the warm outside air resulting in a localized increase in the air temperature around the heat sensor, causing it to activate. There was no negative impact to the facility or risk to the public or the environment.
