When you add wood to a fire, the first smoke that you see is the organic compounds bubbling off from the wood as they evaporate at fairly low temperatures. Flashover happens when hot air from a fire rises to the top of a room which then radiates enough heat for objects in the room to heat up. All courses, Setting up a business Then there is the risk of adding another fuel source to the flames. The radiated heat from this layer heats the surfaces of the directly exposed combustible materials in the room, causing them to give off flammable gases via pyrolysis. Definition of washover in the Definitions.net dictionary. Class C fires are fires involving gases. Some of those combustible materials end up unburned in the smoke. Another concept related to the risk posed by smoke ignition is a fuel's flammable range. This is because there isnt the heat or oxygen needed for the fire to burn properly.

Good housekeeping should help to keep materials like packaging and waste reduced, minimising risks. Most of the fuels we use derive their energy from trapped solar rays. Should You Be Worried? This is because the temperature of most workplaces will not be above the lowest combustible flash point (37.8 C), which means that combustibles wont start to form vapours in a normal working environment. A flashover is the near-simultaneous ignition of most of the directly exposed combustible material in an enclosed area. The nearest fire exit should be taken as long as this is safe to use. This family is called Fire Gas Ignitions (FGI).
