There is an increasing number of car fires along with the increasing numbers of cars. The purpose of this study was to verify the possibility of fires caused by car tuning, which is one of the causes of car fires. The result showed that the possibility of car fires was increased by car tuning including replacement of headlights, excess of allowable current of wires or fuses by using multi cigar jacks, wire damage, earth fault, and vulnerability of wires and cables (sold in auto parts stores) to heat.

Diesel cars employ a diesel particulate filter (DPF) to reduce the discharge of fine dust. However, cases of fires caused by DPFs have been reported in diesel cars. In this study, I examined the regulation of exhaust gas and exhaust gas recirculation in diesel cars. Then, I analyzed cases of car fires caused by DPFs, their characteristics, car fire factors related to DPFs and preventive measures, and their consideration in investigations of the causes of fires. Finally, regarding car fire investigations, this study proposed a process of proving that fires are caused by DPFs.

Purpose: In this study, the status and the risk of fire occurrence in domestic automobile were evaluated and the damage reduction effect by using the fire extinguishing mechanism was evaluated. Method: The analysis of the risk of the occurrence of Vehicle Fires in Korea and the damage of human and property by the use of fire extinguisher applied to fire extinguisher were investigated and analyzed. Results: The annual damage rate of the damage caused by the automobile fire is 4.74%, which shows an annual increase. As a result of the analysis of the personal injury caused by the passenger car in the car fire situation, the damage amount per 100 cases of the fire occurrence increased from 424.65 million won to 473.06 million won in the past 5 years (2012 ~ 2016). Conclusion: When fire extinguishers are used in the case of passenger Vehicle Fires, the average amount of property damage per fire occurrence is estimated to be about 307.5 million, emphasizing the importance and necessity of the initial fire fighting.

Recently, along with the continuous increase in the supply of electric vehicles, electric vehicle fire accidents are also showing a rapidly increasing trend. Electric vehicle fires last for a long time compared to fires in internal combustion engine vehicles and have problems with the risk of secondary explosions and the generation of large amounts of smoke. In particular, electric vehicle fires in underground roads, which are semi-enclosed spaces, may amplify the problems of existing electric vehicle fires. On the other hand, there are no domestic response guidelines for electric vehicle fires occurring inside underground roads. Therefore, an awareness of fire accidents was confirmed through a survey of the general public, and electric vehicle fire characteristics and primary considerations were derived from stakeholders related to electric vehicle fires in underpasses. Through this, the guidelines for responding to electric vehicle fires on underground roads were established.

In recent years, vehicle fires account for the second highest rate after residential fires. It accounts for more than 10.7% of the total fire occurrence rate. Vehicle fires are very difficult to evolve at an early stage. Most of the vehicles are burned down in the event of a fire, resulting in a lot of physical and personal damage. In the EU and other countries, efforts are being made to install automatic fire extinguishing systems in preparation for vehicle fires. In addition, since the automatic fire extinguishing system applied to a vehicle must operate in a moving state of a car, a method for detecting a fire is needed. Therefore, this paper proposes a structure of an automatic fire extinguishing system that can evolve a fire when a fire occurs in a commercial vehicle among various vehicles. Especially, it confirms the feasibility of the automatic fire extinguishing system simulated in the laboratory environment and confirms its applicability.

Because of most notably the increase in vehicular traffic in Korea, as measured by highway transport usage, relief is being sought by expanding the construction of highways after 1970s'. These highways have opened up over 70 % of the mountainous areas in Korea's country side which includes the construction of tunnels. Currently there are 607 tunnels installed that are being maintained and by 2015, under the next medium-term plan, Korea will build an additional 440 tunnels. In addition, the use of 1,000m double-pole tunnels is expected to increase significantly in 256 locations. There is no doubt that these tunnels will relieve traffic congestion and aid improved communications, but halfclosed underground highway tunnels in particular are required to reduce tunnel fires caused by poor vehicle maintenance, and other factors such as speeding motorists that increase the number of vehicular accidents. Double-pole tunnels in 1,000m length over require vehicle drivers to be more cautious in terms of the continuous speed limit, judged by how devastating most of car-crash fires within these tunnels can be. In order to prevent these disasters, a full-length tunnel speed enforcement system should be considered mandatorily in legal clauses.

Fire suppression tests are carried out for a train car using water mist systems. Three kinds of fire scenario applied to the real-scale train car are a surface fire representing car combustibles, a oil pool fire pretending an oil spill and a blocked fire for evaluation of space-cooling capacity. Five fixedpressure water mist systems and one self-contained water mist system with nitrogen gas are used for fire suppression experiments. Almost water mist systems can extinguish effectively train car fires, and fire-control capability of the system is seen due to the space cooling.

As lithium batteries have been used for car navigation systems and as the second battery for black boxes, lithium battery-related car fires have often occurred. In the case a lithium battery is the fire origin, a fire investigation technique has not been established to determine if a battery ignites or whether the lithium battery is damaged by fire. This study introduced car fire cases related to lithium batteries, analyzed the causes of a fire of a lithium battery, and proposed fire investigation techniques to objectively determine if a lithium battery ignites or whether a lithium battery is damaged by fire after external ignition.

This study analyzed the regulatory actions of disposal gas lighters as well as the situations, causes, and preventive measures of fires, and accidents caused by disposal gas lighters. Since child-resistant lighters became mandatory, the percentage of fires caused by playing with fire has decreased in Korea as it did in America and Japan. Fires caused by disposal gas lighters can occur by afterburning, unintentional lighting, large flames, or explosion or bursting as well as by arson and playing with fire. This study suggests the preventive measures of fires caused by disposal gas lighters as follows: Taking a step not to be used as child's tool for playing with fire, the warning of fire cases caused by afterburning, warning of the dangers of leaving disposal gas lighters on the car dashboard or high temperature places, improving the protective synthetic resin cover of the stop part of a vehicle seat rail, and providing information on precautions for keeping in drawers or disposition methods.
