Abstract This research developed and evaluated a measure to examine fire-specific constructs relevant fire misuse. In the first study, using UK community members asked disclose deliberate firesetting, we tested large pool of theoretically informed questionnaire items. First, found that 1 in 10 adults reported setting they had not been apprehended for. Then, exploratory confirmatory factor analy...

The current research investigated the coupling effect of blockage and tunnel slope on spreading characteristics fire smoke ceiling temperature distribution in a metro depot with one closed end. A series 1/15 reduced scale experiments full-scale numerical simulations were conducted to capture global characteristics. investigation addressed compared plume behavior both uphill downhill situations....

To improve numerical simulation of liquid pool fires and remove the need for experimentally measured or empirically calculated mass burning rates as boundary conditions, a fully coupled three-dimensional (3-D) formulation, which directly solves convective motion in fuel region by incorporating inhomogeneous heat feedback, is formulated. The fire dynamics modelled using large eddy (LES) approach...

The present study examines the prevailing conditions in a railway tunnel after train fire accident and ability of ventilation system to create proper for safe passenger evacuation. examined scenario included an event 20-MW diesel pool on suburban train, immobilized middle 1.5-Km long, linear shaped rectangular ventilated by longitudinal jet fan system, people’s movement during evacuation was ef...

This paper examines a number of practical questions about the possibility of using water mist to mitigate explosion hazards in some industrial applications. Water mist systems have been installed to replace Halon 1301 in gas compressor modules on Alaska’s North Slope oil fields. The hazard in the compressor modules includes fire in lubrication oil lines for the gas turbines that drive the compr...

A medium-scale (30 cm diameter) methanol pool fire was simulated using Sandia National Laboratories’ Sierra/Fuego low-Mach number multi-physics turbulent reacting flow code. Large Eddy Simulation (LES) with subgrid kinetic energy closure used as the turbulence model. Combustion modeled a strained laminar flamelet library approach. Radiative heat transfer gray-gas approximation. This paper detai...

This study was conducted to investigate the effects of applying methods andamount of ammonium polyphosphate (0, 2 and 4 wt%) on fire retardancy andmechanical properties of wood flour/polypropylene composites. The resultsshowed that addition of fire retardant improved the mechanical properties such astensile and flexural strengths and fire retardancy of composites. But by increasingof fire retar...
