Northwest Redwater Partnership's (NWR) Sturgeon Refinery was doing some tests.
With several process units undergo commissioning and hydrocarbons beginning to circulate in parts of the refinery, they tested their emergency response.
On August 29, over 4,000 employees at the site took part in an emergency response plan site-wide muster training exercise.
"Simulations are a really effective way to test our plans and equipment," said Kerry Margetts, president of NWR. "This kind of training also benefits the Emergency Operations Centre response team by putting them through the same sequence of steps they would take in the case of a real incident."
The exercise, which included sounding site emergency sirens, gathering at designated locations and accounting for all personnel on site was simulated in real-time.
Training exercises like site-wide mustering helps ensure that all employees and contractors know their role in maintaining a safe and prepared worksite.
