A single piece of furniture on fire could produce enough hot smoke overtime to set everything else in the room with it on fire and a flashover is particularly dangerous because everything catches fire at once with almost no warning! At a certain point in the combustion reaction, called the ignition point, flames are produced. If an object is simply too close to a fire, it could pick up so many waves that its temperature reaches a point that allows it to set alight. Bunker gear provides a false sense of security. Washover definition: The sediment deposited inland of a beach by overwash . We will look at each of the main principles in more detail.

A fire smokes when there is not enough oxygen to sustain the complete burning of whatever is on fire. Good housekeeping should help to keep materials like packaging and waste reduced, minimising risks.
