Fire Brigade came for me tonight... I feel panic...

It was late night, I feel hungry, so I cut some cheese to make baked cheese. After putting those lovely Cheddar and Parmesan into the oven, i got a phone call from friend. Just about 10 min later, I backed to kitchen, open the oven, i found white smoky started to came out, I realized I burned my cheeses. I open all the windows, turn on the fans and vent fans. However, those harsh fire alarm started, I have to went downstairs. Security staff came with nothing to do, it resulted fire brigade came...
