This paper aims at predicting the quality of life, based on mental toughness and organizational commitment. The participants of this study are firefighters working in Tehran in 1397 from different fire stations, among which 150 selected by multistage cluster sampling method. Means of questionnaires conduct the research. The questionnaires used in this study was Quality of life (SF-36), Allen & ...
the effect of forest roads on the extent and type of fire damage occurred in forests and rangelands of the neka county in mazandaran province was investigated. for this purpose, all fire spots, stand number, percentage and type of injury and damage to tree species, and average diameter at breast height (dbh) were noted with 100% inventory; area and geographic location of access roads were deter...
natural fire inflicting irreparable damage to rangelands and forest areas is cause changes in landscape ecology. the purpose of this research is comparison of artificial neural network (ann) and line regression (lr) models to predict of forest and rangelands fires to this end, the data consist fire burned area and fire were used weather data over a period of 7 years (2006-2012(.the result indic...
background: fire and explosion hazards are extremely important in processing units. this study was performed to identify the risk centers, the potential damage caused by fire and explosion, and the days of production cessation in the processing company. materials and methods: the present qualitative case study was conducted using dow’s index in 2015. the fire and explosion hazard index and leve...
A subway station is a confined space, so it very important to evacuate people safely in case of fire. It necessary study and analyze the smoke distribution evacuation ability different layout schemes when fire occurs. Taking as an example, this paper combines BIM (Building Information Model) technology with safety station. First, we optimize public area use establish model. Then, PyroSim softwa...
This study investigates mesoscale mechanisms associated with two extreme heatwaves affecting Santa Barbara County (SBC), southern California, and their implication for severe fire weather. We examine these issues using a database consisting of surface stations, radiosoundings, 1 km grid spacing simulations the Weather Research & Forecasting (WRF), including climatology spanning 32 years. During...
Background and aims Fire and explosion hazards are the first and second of major hazards in process industries, respectively. This study has been done to determine fire and explosion risk severity,radius of exposure and estimating of most probable loss. Methods In this quantitative study process unit has been selected with affecting parameters on fire and explosion risk. Then, it was a...
DDesigned and undersigned fires in rangelands affect vegetation and soil, and then are necessary to give enough knowledge about them. Infiltration is one characteristic that have predict had affected by fire but had not studied enough yet. So spot fire have been seen in Artemisia aucheri type in Charat sub watershed at Mazandaran province, in this research were investigated primary, final infil...
Background and aims Occupational accidents and diseases cost 1.25 thousands billion $ to economic of world & links 2 million annually. Rate of death due to occupational accidents in developing countries in some cases is 4 times to developed industrial countries. To control accidents & resultant damages, identification of potential agents causing accidents in necessary. One of the modern me...
Background and aims: The property loss and physical injuries due to fire events in buildings demonstrate the necessity of implementation of efficient and performance based fire safety measures. Effective and high efficiency protection is possible when design and selection of protection measures are based on risk assessment. This study aims at presenting a software method to make possible sele...
