Evaluation of the Relationship Between Escape Passage Length and Fire Door Pressure Difference
The issue of overpressure at fire doors in escape passage is often overlooked in traditional tunnel design. Current design approaches tend to overemphasize maintaining positive pressure inside the passage for smoke prevention, which results in excessive resistance when opening fire doors. This can…

Governance Failure and Wildfire Escalation: A Multi-Level Analysis of Institutional Preparedness, Corruption, and Emergency Response
Wildfire escalation is increasingly threatening ecosystems and communities in Khyber Pakhtunkhwa (KP), Pakistan, particularly in forest and rangeland landscapes where ecological flammability interacts with human activity. While environmental and climatic drivers are well studied, governance factors…

Thermo-Responsive Hydroxypropyl Methylcellulose and Sodium Alginate Composite Hydrogels and Their Fire Extinguishing Properties
To effectively prevent and control coal spontaneous combustion, a novel heat-sensitive hydrogel for mine fire prevention and extinguishment was developed using hydroxypropyl methylcellulose (HPMC) and the organic flame-retardant, sodium alginate (SA). The hydrogel was prepared through single-factor…

Numerical Simulations of an Under-Ventilated Corridor-like Enclosure Fire
The paper presents computational fluid dynamics (CFD) simulations of a propane-fueled and under-ventilated fire in a reduced-scale corridor-like enclosure. The fire source is positioned at the closed end of the corridor. Due to the restricted inflow of oxygen, the flame lifts off from the gaseous…

Comparative Evaluation of Single, Binary, and Ternary Biodiesel Blends of CSOME, NOME, and OPOME for Performance and Emission Optimization in a CI Engine
Biodiesel’s application in compression–ignition engines is mostly limited by the type of methyl esters it contains rather than the total amount of feedstocks. In order to modify the fatty acid methyl ester (FAME) profile for better combustion and emissions, cottonseed (CSOME), neem (NOME), and…

Evacuation Patterns of Occupant Groups in Super High-Rise Building Stairwells Under Different Visibility Conditions
Stairwells constitute critical escape routes for emergency evacuation during building disasters. The spread of fire smoke and the failure of lighting systems can significantly reduce visibility within stairwells, thereby adversely affecting evacuation speed. This issue is particularly pronounced in…

Early Wildfire Smoke Detection with a Multi-Resolution Framework and Two-Stage Classification Pipeline
Early wildfire smoke detection is critical for preventing small ignitions from escalating into large-scale fires, yet early-stage smoke plumes are often faint, low-contrast, and spatially small. When full-resolution frames are resized to satisfy fixed-input detector architectures and enable…

A Land Cover Recognition-Based Method for Wildfire Early Warning in Transmission Corridor Areas
To improve the accuracy of wildfire risk identification in areas adjacent to power transmission corridors, this study proposes a wildfire early warning method that integrates refined land cover segmentation and multimodal feature deep learning. First, an improved bi-branch semantic segmentation…

Observations of Vorticity-Driven Lateral Spread in a Wildfire
Video footage of a recent California wildfire confirmed that dangerous fire spread can lead to unsurvivable foreground conditions. This process thus needs enhanced awareness across the wildfire sector. The fire moved sideways, downwind of a ridgeline, and formed dense, rapidly spreading spot-fires…

DC Series Arc Fault Detection in Photovoltaic Systems Using a Hybrid WDCNN-BiLSTM-CA Model
Arc fault is the dominant cause of fire in photovoltaic (PV) systems, making its accurate identification crucial for PV fire prevention. This study investigates the influence of voltage (200, 300, and 400 V) and current (3, 5, 7, 9, and 11 A) on the DC series arc fault characteristics in PV systems…
