Small metal fires can sometimes be smothered with dry earth or sand. Flashover occurs when the majority of the exposed surfaces in a space are heated to their autoignition temperature and emit flammable gases (see also flash point). 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. There are six classes of fire, and each should be attacked differently to put them out safely. These temperatures vary from material to material, but there are certain flash point thresholds that separate flammables from combustibles. The existence of a third family of fire phenomena is less known however. The fire is in a ventilated compartment, so there is no shortage of oxygen in the room. Lifts should not be used unless they are part of a Personal Emergency Evacuation Plan (these will be covered soon). At all times in the workplace, you should have access to an emergency exit.
