A Fire and Emergency New Zealand training exercise at the Z Energy tanks in Fryatt St, Dunedin, yesterday was hailed as a success by the organiser.
Yesterday, however, was just about checking response times and putting not only firefighters through their paces, but also the workers on site.
Senior Station Officer Martin Hastie said any kind of emergency at the site prompted a third alarm to be sounded immediately, calling in multiple crews and appliances, as well as a command centre and a safe point to be set up.
"We simulated a real incident where we got them to call 111 and we simulated that the pumps had broken down."
He said it was a real "worst-case-scenario-type thing", but it made sure if the worst did happen everyone knew what to so and the systems were up to scratch.
