Many contributing factors affect fire development. At its initial stages, fire development is mainly influenced by fuel supply, which is oxygen. As we know, oxygen gas takes approximately 21 percent of the total air composition a clear indication of its abundance in our environment. In principle, once it starts, it will follow natural path of least resistance as it moves up and away simultaneously from its original point. All fires have a common pattern that they follow i.e. burning combustible materials around it as it spreads while following path of least resistance. With time and as fire spreads around, other environmental factors such as building design, the quantity of additional fuel accessible, materials used in structure constructing and the quantity of oxygen gas immediate area play a major role in influence the rate and extend to which fire will spread. Classification of Fires Fire is categorized basing on the kind of fuel or substance that is burning. NFPA has managed to categorize fire by fuel into the following tabulated types. Type of Fire  Fuel/Material consumed                                                                                                                            Class A       Ordinary burnable materials or those substances that generate coals, ash or glowing embers when burnt. For instance rubber, wood, paper and cloth Class B       Burnable or flammable liquids. For example alcohol, gasoline liquid, fuel oil and common kerosene                                                 Class C       Energized electrical machines                                                                                                                     Class D       flammable metals for example titanium and magnesium.                                                                                               Fire Development (Stages of Fires) Fire begins instantly when four constituents of fire tetrahedron merge. In the initial stages of fire development, heat generated goes up and creates a plume of hot gas. For fire to spread away from the first material, it is necessary heat generated from the first material to spread to other neighboring fuel packages so that this kind of cycle continues and in the process fire spreads. In open space, fire plume moves up unhindered, and atmosphere air is drawn in as fire plume moves up. Air drawn into the flame is at lower temperature than fire gases and as a result, gases above the fire are cooled. The spread of fire in an open area is chiefly due to heat energy that is transmitted from the plume to nearby fuels. The rate of at which fire spreads outside is propelled by sloping train, amount of oxygen being drain in and wind that facilitates preheating of the uncovered fuel. The mechanism by which fire spread in a compartment or partition is multifaceted unlike for open space. In this paper, a compartment is considered as an enclosed space or room is a given building. As the term suggests, compartment fire is normally proscribed by amount of oxygen and fuel accessible. When the quantity of oxygen gas accessible is inadequate, such state is referred to as ventilation controlled. On the other hand, when quantity of fuel accessible to burn is inadequate, the fire is fuel controlled. In recent times, there have been attempts to categorize compartment fires basing on transfo
