Oxygen exists not only in gas form but also in liquid form. These types of oxygen are found in liquid chemicals with high active oxygen content. The fundamental example is methyl ethyl ketone peroxide. This type of liquid chemical is hazardous because it is a complete package of two of the most important components in fire production, fuel and oxygen. What it only needs to ignite is heat. Thus, this chemical needs to monitor its self-accelerating decomposition temperature. Studies have shown that high oxygen concentration and pressure at a high temperature contributed to fire and explosion (Yun et al.
, 2007; Lautkaski, 2008; Hirano and Sato, 1993). This only means that there are specific requirements in the ignition process, and it requires oxygen to be in the exact pressure and concentration to ensure fire burning in the fuel. In short, oxygen is just a supporting agent in the creation of fire. However, without its presence, there can be no fire created. The results of various studies that aim to study the significance of oxygen in the creation of fire only prove that ignition combines the necessary components of fire production.
It is important to understand that the making of fire does not only involve oxygen alone. The other component in fire production that needs to be clearly understood is fuel. Another important component of fire production is fuel. There are different classifications of fuel, and they can be solid, liquid or vapour. In other words, the three phases of matter can be ignited and be defined as fuel. Anything that fire can consume is fuel. However, in industrial cities, fuels are mostly found in Industries that are highly exposed to combustible materials.
They are characterized according to their size, moisture content, flammability and location (Nunamaker, 2011). Intuitively, small fuels are easily consumed by fire, but the larger ones take time. However, once they started to ignite, it will take enough time for them to be totally consumed by fire. In the same way, those fuels with a large amount of moisture take time to be ignited.
