Firefighting mobile suit is thermally superior to activewear, but activewear is increased to thermal protection performance. However, it was showed that activewear melted and dripped, accelerating the degree of burns. It was confirmed that in order to lighten the heat barrier layer, bulking of low weight is necessary, and the 3D spacer fabric has a high weight, so the height of the pile yarn must be greatly increased. In the case of turnout gear, the thermal barrier layer was the highest in parts of weight and heat, and the outershell and moisture barrier were in that order, confirming that the felt layer and outershell are important for weight reduction. In particular, it was confirmed that when 80gsm aramid padding was used for the felt layer, it was similar to the currently used 150gsm felt and could be replaced. Comparison of the radiant heat performance of m-aramid turnout gear’s outershell showed that the function deteriorated starting from 40kW/ , while PBI, PBO, and p-aramid decreased rapidly starting from 30kW/ , and the color became darker due to carbonization of the outershell due to high radiant heat. As the heat flux density of m-aramid increased, the shrinkage was more severe than that of other outershell. As a result of a flash fire test(ISO 13506) on four types of turnout gear, the degree of second and third degree burns was 17.9% for m-aramid, 6.4% for p-aramid, 9.6% for PBI, and 13.0% for PBO, confirming poor reproducibility and reliability. In particular, it was confirmed that testing with an ensemble is suitable for a realistic real fire test.
