Deskripsi
The article examined selected individual protection used during rescue and fire-extinguishing activities. Fire helmet and special shoes were examined under conditions resembling the operational conditions of LNG gases. The assessment of the equipment consumption was based on strength tests. The main threats come from thermal and mechanical factors. Therefore, firefighters must properly protect their head and legs. At −80 °C, the energy of the impact force of the beater in the headache was, 12.4 J and 15.1 J for points P1 and P2, respectively. The studies showed that cooling the chamber to −80 °C adversely affected the structure of the fire helmet exposed to impact Dynamic. Research work was carried out as part of the Research and Development project No. DOB-BIO9/15/02/2018.
