False nuclear alarm in Ontario was due to human error, investigation finds
TORONTO — A false alarm about an incident at the Pickering Nuclear Generating Station last month was the result of human error, but a delay in sending an all clear was due to several systemic issues, a report found Thursday.
The alert was pushed to cellphones, radios and TVs across the province on the morning of Sunday, Jan. 12.
The duty officer at the Provincial Emergency Operations Centre is supposed to test both a live alert and a training system at shift changes, and on that day the officer thought they had logged out of the live system and into the training one when the alert was sent, according to a report from the chief of Emergency Management Ontario.
The officer immediately realized the error and asked supervisors how to fix it, but they were uncertain about whether or how to send a corrective alert to everyone who had seen the first, the report said.
