If there is a fire then follow: Fire instructions
Kitchen fire: Fire inside the kitchen
There is a fire alarm at every kitchen and a central warning system. If the alarm is triggered when cooking then it can be disabled by pressing silence alarm on the box above the kitchen door. The magnet that keeps the door open is disabled when the alarm is active. The alarm needs to be silenced before the magnet will function. That way the kitchen door is kept closed when the alrm is active.
