It is extremely worrying for our community and I am concerned for employees who were on site. “I want to thank the emergency services for their professionalism and bravery, and residents for their adherence to guidance. It is very important to keep at least 70 metres away from the scene and please close doors and windows if you are near the area. Avoid breathing in any smoke and stay indoors.”
