A daunting mine disaster took place in 13 May 2014 at Soma and 301 men lost their lives. Brief information about the Eynez coal mine and some of the inherent characteristics of the field in terms of their effects on mining are presented. This paper basically concentrates on the factors that played an important role in the occurrence of this disaster. Progress of mine fire, firefighting, and res...
The Upper Guinean region of West Africa exhibits strong geographic variation in land use, climate, vegetation, and human population and has experienced phenomenal biophysical and socio-economic changes in recent decades. All of these factors influence spatial heterogeneity and temporal trends in fires, but their combined effects on fire regimes are not well understood. The main objectives of th...
In 1973, the President of the United States commissioned a study of America’s fire problem. The United States was suffering much greater losses in terms of fire deaths, injuries, and economic loss than other industrialized nations. The resulting report highlighted a need for the American fire service to place a greater emphasis on fire prevention. After the release of this report, the fire prob...
Vision based fire detection is potentially a useful technique. With the increase in the number of surveillance cameras being installed, a vision based fire detection capability can be incorporated in existing surveillance systems at relatively low additional cost. Vision based fire detection offers advantages over the traditional methods. It will thus complement the existing devices. Convention...
This paper presents a development of the forest fire detection algorithm for upcoming GCOM-C1/SGLI sensor. Several existing fire detection algorithms which are applied to GOES/VAS, NOAA/AHVRR, Terra Aqua/MODIS sensors mainly use the MIR fire channels(3-4μm) for key role of the fire detection algorithm. Meanwhile, because of lack of the MIR fire channel on GCOM-C1/SGLI, fire detection algorithm ...
Fire-tower is effectively applied in forest fire prevention and commanding system, especially in fire monitor and position. After explaining the significance of scientific planning of fire-tower, this paper analyzes GIS`s functions in building forest fire prevention system. This paper uses case study method, which designs a model, fire tower planning and analysis, based on MapGIS platform. Afte...
Fire fighters are at risk of falling through fire-damaged floors. Fire burning underneath floors can significantly degrade the floor system with little indication to fire fighters working above. Floors can fail within minutes of fire exposure, and new construction technology such as engineered wood floor joists may fail sooner than traditional construction methods. NIOSH recommends that fire fi...
WRF-Fire consists of the WRF (Weather Research and Forecasting Model) coupled with a fire spread model, based on the levelset method. We describe a preliminary application of WRF-Fire to a forest fire in Bulgaria, oportunities for research of forest fire models for Bulgaria, and plans for the development of an Environmental Decision Support Systems which includes computational modeling of fire ...
The issue of fire propagation in cities is of obvious importance to Civil Authorities, but does present issues of computational complexity. Our basic assumption is that some event has occurred to disrupt the normal damage prevention infrastructure, i.e. the Fire Department, so that the fire spreads unhindered through the city. For the most part, the spread of fire is stopped inside the building...
Theory suggests that natural fire regimes can result in landscapes that are both self-regulating and resilient to fire. For example, because fires consume fuel, they may create barriers to the spread of future fires, thereby regulating fire size. Top-down controls such as weather, however, can weaken this effect. While empirical examples demonstrating this pattern-process feedback between veget...
