Farming activity was the second cause of forest fire following the carelessness. In this study, 74 forest fires caused by farming activity and waste burning in 2009 was investigated for analyzing ignition patterns. The main cause to bring about forest fire was the farming waste burning as 25 cases, burning of farming waste matter after product and household waste burning were the second causes as 19 cases. Landcovers which transfer flame from ignition point to forest were fallow field graveyard, field fruit farm, field levee fallow field. The average distance between ignition point and forest sleeve was 19 m, and the maximum distance was 130 m. The probability of forest fire ignition was high in the 100 m buffer zone from the forest sleeve that is the prohibition rule of fire use for forest fire prevention at the forest fire season.

This paper carried out a variety of analysis for a finding out the causes of fire on the street lamp. The glass bulb of 250W metal-halide(MH) lamps attached with the impurities rose the temperature by at $410.4^{\circ}$ in normal condition. Therefore, a lamp apparatus is needed the improvement for ventilation and the protection against dust. The heat of MH lamps is diffused through out the luminous tube, a glass bulb, and apparatus by degrees. The accident cause of the lamp is presumed that the accumulated heat by deposits of the inner part. It will be recommended the improvement of the structure that aren't the external impurity and accumulated heat in the MH lamps set.

This paper aims to study structural changes in electric conductors which are heated during electric fire by means of microscope. The results are applicable to the pursuit of the causes of electric fire and to the establishment of criteria for the indentification of electric fire. This work is an extension of the previous study by the author, particularly with emphasis on quantitative analysis.

As structures are higher, large-sized and more complex, we should detect the fire at the beginning and cope with it to reduce the loss of mankind and the physical damage due to fire. So we have investigated and developed various kinds of fire detection system, and do the efforts for minimizing the nonfire alarm. As there exists a close relationship between the technology development and the market potential, a comparison between the number of fires in special buildings and detection types were made to find out market potential based on the annual statistics on fire products inspection. In addition, we have discussed the causes of nonfire alarm and the fire detection system and prospect the research trend of the fire detection system.

This paper presents development of a classification system for an electrical fire investigation. In order to reduce an electrical fires and establish detailed prevention plans, the collection of an electrical fire causes and base data are very important. Based on this data, a new classification system for an electrical fire investigation was developed and the direction to the classification system was suggested by fundamental analysis. All of the collected information is analyzed by bottom-up method. Criteria items which based on base data were categorized to classify items. The classification of items were found out as follows : basic condition fire scene condition, fire sign, fire cause. Particularly, the fire cause category is classified. A new developed classification system for an electrical fire investigation will be used to analyse electrical fires easily and efficiently.

Currently, safety management is becoming important at domestic construction sites. Despite the importance of safety management, accidents at construction sites are steadily increasing. Fire accidents among safety accidents cause not only negative effects on schedule delay or work plans at construction sites, but also huge casualties. Therefore, the purpose of this research is to extract the causes of fire at the construction site through the case of fire at the construction site, and to prioritize prevention through the analysis of the factors to contribute to the prevention of fire. As a research method, we select fire factors through case, conduct surveys through expert group, and analyze survey through AHP technique. The results of the AHP analysis of the survey of expert groups showed that the workers and their sub-item ranked high. Therefore, the priority for fire prevention was given, and this research is believed to help prevent fire.

Recently, fire and explosion accidents caused by sparks scattered during welding and melting work in the work place where flammables are present. The causes of such fire accidents are mostly non-compliance with basic safety rules such as the removal of hazardous goods and the prevention of sparks scattering. It is strongly recommended to revise Industrial Safety and Health Act. This study analyzes the fire and explosion accidents in the work of firearms, such as welding and melting work, and analyzes the causes from a system perspective, and proposes an improvement plan for the system such as expanding the number of fire monitors, pre-approval of fire risk work, and intensifying fire prevention safety education.

A study on the fire scenario proposal of residential facilities by using fire statistics. as a result of analyzing residential facilities fires by using fire statistics of national emergency management agency during 2007~2012, fires from carelessness were the most causes. specially, fires during food cooking among carelessness showed the highest occurrence frequency, and followed sparks, neglecting fire sources, and cigarette stubs in order. through this the study suggested fire scenarios according, It is believed that can be used as basic data for applying a secure building in a fire using a basis for fire safety design of buildings in the future this.

The fire should extinguish as soon as possible because it causes economic loss and loses precious life. In this study, we propose a new atypical fire and smoke detection algorithm using deep learning and color histogram of fire and smoke. First, input frame images obtain from the ONVIF surveillance camera mounted in factory search motion candidate frame by motion detection algorithm and mean square error (MSE). Second deep learning (Faster R-CNN) is used to extract the fire and smoke candidate area of motion frame. Third, we apply a novel algorithm to detect the fire and smoke using color histogram algorithm with local area motion, similarity, and MSE. In this study, we developed a novel fire and smoke detection algorithm applied the local motion and color histogram method. Experimental results show that the surveillance camera with the proposed algorithm showed good fire and smoke detection results with very few false positives.
