Dipping-baking process was used for finishing cotton fabrics. Surface morphology, surface functional group and element distribution, intrinsic crystal structure, pyrolysis characteristics and flame retardancy of cotton fabrics were characterized by Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), thermogravimetric analysis (TG), and limiting oxygen index (LOI). Results show that DOPO and SiO2sol have good synergistic flame retardant effect. Cotton fabric finished by hybrid sol of SiO2-KH570-DOPO has the best flame retardant effect, its LOI is 22.8 %, ΔLOI/Δm is 4.20 %/g. DOPO-contained hybrid sol can promote formation of three-dimensional microscopic gel coating and residual char in condensed phase.","PeriodicalId":6687,"journal":{"name":"2019 9th International Conference on Fire Science and Fire Protection Engineering (ICFSFPE)","volume":"12 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85567872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is necessary to study the functional system and strategies of forest firefighting. In this paper, the characteristics of forest fire fighting are analyzed. It is found that forest fire has the characteristics of many combustibles, large area of fire, fast the spread of the speed and high intensity of fire. It takes a long time to put out forest fire. In the forest fire fighting, it also has the characteristics of high risk and uncertain risk factors, which affect fire fighting safety. Aiming at these difficulties and risk factors in forest fire fighting, this paper discusses and studies the fire fighting function system, and puts forward the function system of forest fire fighting and rescue based on cognition, command, control and support function modules, referred to as CCCS function system, in order to improve the efficiency of forest fire fighting. Based on this system, some fire extinguishing strategies are put forward, hoping to provide some reference for forest fire extinguishing and rescue.","PeriodicalId":6687,"journal":{"name":"2019 9th International Conference on Fire Science and Fire Protection Engineering (ICFSFPE)","volume":"20 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91157056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The passenger cabin space of bus is relatively small. Once a fire occurred, high temperature, thermal radiation and smoke generated by combustion will cause great difficulties for personnel evacuation. Aiming at the requirements of Chinese GA1264-2015, this paper carried out full-scale fire-extinguishing experiments in the bus cabin. The parameters of temperature distribution, smoke concentration and fire-fighting time in the passenger cabin of the bus are analyzed, so as to verify the fire-fighting performance of the self-developed water-based fire extinguishing agent and the fixed fire-extinguishing system in the passenger cabin. The system can put out fire quickly and efficiently. Moreover, it can effectively reduce temperature and concentration of toxic and harmful gases in the cabin after the fire. It could obviously improve the fire protection capacity.","PeriodicalId":6687,"journal":{"name":"2019 9th International Conference on Fire Science and Fire Protection Engineering (ICFSFPE)","volume":"43 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91202047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The principle of point extraction ventilation is that sufficient exhaust volumetric flow rate is supplied to confine the smoke to an acceptable zone. However, the issue of an appropriate exhaust volumetric flow rate to confine the smoke to a safe zone has not been studied sufficiently. In this study, the critical exhaust volumetric flow rate to control the smoke to the zone between two extraction vents was proposed and a series of small-scale experiments were carried out to investigate the effect of extraction vent length on the critical exhaust volumetric flow rate. The heat release rate (HRR), extraction vent length and the distance between two vents varied during the tests. Smoke temperature below the ceiling and smoke configurations were measured and analyzed. Experimental results show that it is not the case that the longer the extraction vent, the smaller the critical exhaust volumetric flow rate. There exists a critical extraction vent length that is 0.1 m in the current study. Finally, an empirical equation was developed to predict the critical exhaust volumetric flow rate based on theoretical analysis. The coefficients in the equation were determined by experimental data. Compared with experimental data, it is obvious that the derived equation can well predict the critical exhaust volumetric flow rate. Research outcomes can provide some helpful references for the design of point extraction ventilation in the tunnel fire.","PeriodicalId":6687,"journal":{"name":"2019 9th International Conference on Fire Science and Fire Protection Engineering (ICFSFPE)","volume":"222 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73352521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By changing fire source position and the environment air velocity, the writer compares the fire temperature field and smoke concentretion under different working conditions to the influence of detection alarm system effectiveness. The results show that when the corridor space structure is T-shaped, the detection system is more likely to get fire signal and alarm. When the position of the fire source changes, the fire source energy at the corner of the L-shaped tunnel is first monitored by the cable-type linear temperature detector. In the L-type tunnel, when the wind speed increases, the time of point-type temperature detector and cable-type linear temperature detector increases, and the wind speed keeps increasing, the point-type temperature detector fails to alarm. In the T-type tunnel, the time of point-type smoke detector and cable-type linear temperature detector increases as the wind speed increases.","PeriodicalId":6687,"journal":{"name":"2019 9th International Conference on Fire Science and Fire Protection Engineering (ICFSFPE)","volume":"5 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78485598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
