BACKGROUND Unintentional injuries are the most common cause of morbidity and mortality in young children, and most injuries occur in the home. OBJECTIVES To report findings from a primary prevention program that trained paramedics to conduct home safety surveys, provide family safety education, and identify common pediatric injury risks in the home. METHODS We retrospectively reviewed stand...
Background and aims: From the 70s onwards, safety engineering made significant progress in developing techniques and regulations relating to the fire. The first, this methods was considered after happening accidents to prevent similar accidents. But with the advancement of technology, the prediction and prevention of fire in complex industries such as power plant finds Important. This study is...
Hyperspectral remote sensing imagery contains much more information in the spectral domain than does multispectral imagery. The consecutive and abundant spectral signals provide a great potential for classification and anomaly detection. In this study, two real hyperspectral data sets were used for anomaly detection. One data set was an Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) da...
temporal and spatial variations of fire behavior can be predicted using one of the semi-physical or empirical models developed over recent years. this article investigates the effect of different fuel moisture conditions on fire spread and behavior in national golestan park in july 2011 using farsite, flammap simulation systems, and previous ignition history. landscape data contains the topogra...
Fire and Gas (F&G) detection is an essential part of the mitigation system in facilities handling and storing flammable and toxic materials. While detector reliability might be very high, safety performance of a F&G system strongly depends on layout and coverage. Current reference standards for on-shore applications do not define the plant areas to be mapped, the coverage targets, and the refer...
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...
LPG cylinder leakage is one of the causes fires in community. To prevent fires, a fire and gas leak detection monitoring device were made using detector sensor an Android-based MQ-6 to trigger it. Data collection techniques manufacture flame can be obtained from datasheets, journals, books articles, several internet sites that support this device. In devices or tools, there are also two parts, ...
