Fire in the park

When I was walking home yesterday there was a large fire in one of the BBQ places in the park. Generally when the BBQs are going they aren't as large as the fire last night. Though it was large, it wasn't out of control so it was safe in that way. However, there wasn't anyone in sight but there was a tent right by the fire so there may have been someone in the tent. The danger is that the tent was so close to the fire that it could have caught on fire. So I was trying to sort out if I should call the emergency number or the non emergency number (because it wasn't an emergency yet). But while I was thinking that through I heard the sound of the sirens.
