ABSTRACT


This project centers on addressing the issue of the lack of research and development in Nigeria, in this case, looking into the firefighting and emergency sector. In this industry, the safety of the firefighters is of paramount importance as it is only then that they can fully carry out their duties and tasks. Of all the products that make up a complete assemble of the firefighters’ PPE, it is their personal protective tunic that was used for this project as it is the basic and most important part of the PPE. The city of Ota was used as a case study due to the high concentration of industries which makes it a target for pipeline explosions amongst others. A performance assessment was carried out on an obtained sample material of the firefighters’ personal protective tunic. Four tests were performed to determine the thermophysical and elemental properties of the material. The following results were got: thermal conductivity of 2.47 W/mK and calorific value of 24020.46 kJ/kg. The elemental analysis showed that the sample material contained the carbon, hydrogen and oxygen elements in the molecular ratio of 27:38:14 respectively. The obtained results for the thermophysical properties did not correspond with that of international standards for known firefighter tunic materials such as Nomex and Kevlar and so is not suitable for use. This project seeks to make this information available to stakeholders in the firefighting industry and proffer recommendations for the necessary upgrade on the standard of protective tunics used in fire stations.
