Early detection of a fire and the signaling of an appropriate alarm remain significant factors in the prevention of major fire losses. Properly installed and controlled fire warning and alarm systems could help improve the safety of residents and emergency responders while reducing property damages.\n An oxidizing agent (usually oxygen) must be available in order for a flame to break out. The atmosphere is largely made up of petroleum products – consequently oxygen is always present and ready to react. Another requirement must be fulfilled for a flame to break out: the ignition energy (heat) can be set off by electrical explosion (e.g. lightning), short-circuits, airborne sparks, warm surfaces (light bulbs, heating appliances, etc.), direct exposure to fire and wrapped illumination, to list but a few. \n Incipient stage: a little bit of visible smoke occurs, but a lot of invisible aerosols are produced in particular.\n Smoldering stage: in this process, the flame may be extinguished by means of a fire extinguisher or other extinguishing agent. Visible, partially dense smoke occurs. In general, the combustion is incomplete, which is why a lot of (toxic) CO is produced at this stage. \n Flaming stage: we are faced with an (open fire to combat the fire brigade) open fire that has to be extinguished by the fire brigade. As enough energy is available, the combustion cycle is almost complete, resulting in high CO2 emissions.
