This thesis shows that the external factors of latex products could cause a fire. Nowadays, as many people are interested in a deep sleep, fire accidents have increased since their preference for latex mattress got higher. This study suggests the fire risk of latex products and the plan for improvement for the recurrence of a similar fire. For it, they use three kinds of latex mattresses for their experiments. Firstly, they observe a temperature change in thermal heat build-up. Secondly, they check a flaming fire under smoldering combustion by thermal heat build-up. Lastly, they analyze heat release rate and detection density by the outbreak of toxic gases after the experiments from the above.

Big data and AI-based automobile service technology should be understood not only in the coming future but also in the advanced technology such as artificial intelligence, and CCOS automobile recorder should be understood and applied to automobile fire investigation. There are many recording devices such as OBD (On Board Diagnosis), EDR (Event Data Recorder), and DTG (Digital Tachograph) in the vehicle. However, when the vehicle is burned down, the recording devices installed in the vehicle are lost and the recorded information disappears. Recently, the problem that the recorded information is recorded and stored in the Internet server by using the wireless communication network is also solved. The information collected in the CCOS-based recording device in the vehicle should be combined with the fire investigation to help identify the cause and reinforce it as evidence to enhance external credibility

In modern society, where electrical lighting has become common, similar types of fires are occurring without boiling, despite the use of candles mainly for religious ceremonies such as mass, ancestral rites, prayer, purpose of deodorization, power outages, and stabilization of mind and body. News of fires during candlelight events comes more frequently during Christmas than Santa Claus, and it is not uncommon for small candles in a generation where electricity is cut off due to living conditions to swallow combustibles around them and cause casualties. These candle fires occur in an instant, regardless of the presence or absence of a person around the candle, and the expansion of combustion often causes great property damage and casualties

Recently, economic downturn and the era of ultra-high oil prices caused by the global pandemic, demand for the installation of wood boilers in home or rural houses is increasing as a means of reducing heating costs in winter. In general, wood boilers, which have been used a lot in factories and warehouses, not only reduce the burden of heating costs, which account for a large part of household spending in winter, but also are simple and economical, so the demand is gradually increasing. However, due to the nature of the fuel, it is difficult to control the fire power, and there is no accurate installation manual, so there is a high possibility of fire, such as overheating of the stovepipe and splashing on nearby combustibles. In addition, there are many problems that were not initially expected during the manufacture and installation of the wood boiler due to legal defects. This study aims to analyze fire hazards according to communication structure, material, and boiler room construction materials by conducting fire re-experiments based on fire cases by wood boilers, and provide basic data for safe installation and use of fire boilers.

Recently, many large-scale fires have occurred due to problems such as performance tests of sandwich panel finishing materials and insulation materials.. In the case of a large fire, combustible materials are burnt out before the fire brigade's golden time (7 minutes) and the fire pattern and evidence are lost, making it difficult to identify the cause and point of ignition. In order to point out these problems, the risk of combustible insulating material (Expandable Polystyrene Foam) was revealed and non-combustible material (Glass wool), a study was conducted to recommend it.

Since the implementation of the Product Liability Act, there have been many cases of disputes over various electronic products, and fire cases have recently appeared in bidets. In the case of a fire in a house where a bidet is mainly used, there is a great possibility of personal injury, and the majority of people do not know the possibility of a fire in a bidet. Therefore, we will examine the structure and principle of the bidet, study various fire statistics and cases, analyze the ignition mechanism through fire reproduction experiments under various conditions, develop a fire investigation technique (SOP), and predict the overall characteristics of the electronic bidet and the possibility of ignition to approach the theoretical consideration.
