Buildings in modern society tend to gradually expand size due technological development and overcrowding, which increases the risk of fire. Therefore, continuous efforts are being made ensure evacuation safety occupants by installing firefighting facilities using flame retardant building finishing materials. This study aims present a fire performance evaluation plan for materials simulations id...
Background & Objectives: Educational and research laboratories in universities have a high risk of fire, because they have a variety of materials and equipment. The aim of this study was to provide a technical plan for safety improvement in educational and research laboratories of a university based on the design of automatic detection, alarm, and extinguishing systems . Method...
Forest fire models are generally used in different aspects of fire management and are helpful in understanding and prediction of fire behavior. Forest fires cause a significant damage for public property by destroying a large tract of forest. This helps fire fighters to focus on an area with greater risk and to develop better substructure for fire fighter training and ultimately to plan fire-f...
One of the most interesting problems in fire detection system design is problem referred to as detector position on a ?honeycomb ceiling?, because beams and joists affect stratification smoke and, consequently, response time. The aim this paper determine optimal placement - underside or structural slab cells. On basis rules standards for location, Large Eddy Simulation method Fire Dynamics Simu...
Introduction: There are risk of fire accidents in Operating rooms during surgery. Experts estimate annually around 100 fire accidents occur in the operating rooms of United States’s hospitals. 10 to 20 of these accidents lead to severe injuries and about 1 to 2 lead to death. Despite such accidents rarely happen, but they can lead to serious injury or death of patients. .Material and Metho...
The utilization of natural resources and energy is increasing day by day, one which the use gas as fuel for both household industrial needs. Safety aspects in this must be considered because leaks can trigger fires. Therefore we need a tool that detect notify early possible. This study proposes leak detector based on Internet Things (IoT) using NodeMCU ESP8266 microcontroller. detection system ...
In this work, a robust stand-off alpha detection method using the secondary effects of alpha radiation has been sought. Alpha particles ionise the surrounding atmosphere as they travel. Fluorescence photons produced as a consequence of this can be used to detect the source of the alpha emissions. This paper details experiments carried out to detect this fluorescence, with the focus on photons i...
