The paper "Small Scale Compartment Fire" is a wonderful example of a lab report on engineering and construction.   The combustion that takes place of the hot gases and the flames may be ejected out of the building through the windows and the doors. The ejection of the flame may occur suddenly that may enhance the flame to rapidly flow to other compartments. Objects that are in the vicinity may be ignited leading to the spread of fire out of the building. In a scenario where the flame exhaust occurs through an opening, it takes place through ventilation that is controlled.

This scenario is mostly associated with the flashovers and may pose as a health hazard to the facilities that are hydrocarbon. Ideally, the induction period which represents the time delay that occurs between the time of a given ignition and the exhaust of flame forms an important basis in ascertaining the characteristics of fire under the fire investigations. Analysis of the enclosed fire also aid in ascertaining the extent to which the fire would grow and the extent to which it would affect the buildings Introduction Ideally, the fire that emanates from a compartment occurs in a closed space.

They may arise as a result of fuel control where there is in-adequate air required to react with all the fuel in a given enclose. Additionally, it may arise due to ventilation limited due to limited air supply (Chandler, 2009). Various compartments exhibit different stages of fire such as the ignition stage, growth stage, flashover stage, fully developed stage as well as the decay stage. Early-stage This stage, the compartment exhibits no effect on the development and the growth of the fire.

A layer would be formed under the ceiling as it flows out of the compartments. This results from the smoke and the hot gases (Lataille, 2003). In the event that fire continues to grow while the openings are small to carry the products of combustion away faster or, at the same rate than they are being generated, the upper layer would increase and start descending towards the floor (Great Britain. , 2006). The compartment would be fully involved in the scenario where the fire has developed and flashover has been developed. Thereafter, the fire would decay till when all the fuel is consumed and it extinguishes itself. Aim This experiment aims at establishing how the fire from the compartments may develop from ignition to flashover as well as decay. Hypothesis There is a relationship between the time to ignition and the size of the opening. There is a relationship between the effect of temperature and time to ignition 2 Methodology This experiment utilizes a firebox and a thermocouple.

The firebox represents a small compartment that has a dimension of (0.65m long by 0.34m wide by 0.38m high) It has the roofs and the walls having a 0.025m external layer having monolux 500 while one of the walls is constructed from a fire-resistant material glass.

There was an adjustable door that is 225 high that opens between 0-0.15m wide. A hole was made on the floor so as to pass the axle that would support the fuel as well as enabling the weight of the material being recorded. It was placed so as to ensure that the center locates itself as 0.45m. To ensure easy movements, the firebox was fixed in a steel frame that had the wheels that enhanced easy movement when needed.

Three columns were placed in conjunction with the thermocouples that are located on the wall of the compartment.
