Many of the photovoltaic (PV) systems on buildings are of sufficiently high voltages, with potential to cause or promote fires. However, research about photovoltaic fires is insufficient. This paper focuses on the flammability and fire hazards of photovoltaic modules. Bench-scale experiments based on polycrystalline silicon PV modules have been conducted using a cone calorimeter. Several parameters including ignition time (), mass loss, heat release rate (HRR), carbon monoxide (CO) and carbon dioxide (CO₂) concentration, were investigated. The fire behaviours, fire hazards and toxicity of gases released by PV modules are assessed based on experimental results. The results show that PV modules under tests are inflammable with the critical heat flux of 26 kW/m². This work will lead to better understanding on photovoltaic fires and how to help authorities determine the appropriate fire safety provisions for controlling photovoltaic fires.

The Ijen crater volcano (ICV) is one of the active volcanoes with unique environmental conditions; it is the largest lake in the world with the most extreme acidity and a blue fire phenomenon and releases toxic volcanic gases, including dangerous sulfur dioxide (SO₂). It has an impact on the environment and ecosystem. This research aimed to investigate the blue fire phenomena and toxic gas SO and characterize the environmental conditions and health effects of the ICV.

Arc detection is crucial for ensuring the safe operation of power systems, where timely and accurate detection of arcs can prevent potential hazards such as fires, equipment damage, or system failures. Traditional arc detection methods, while functional, often suffer from low detection accuracy and high computational complexity, especially in complex operational environments. This limitation is particularly problematic in real-time monitoring and the efficient operation of power systems.

Metal-organic framework (MOF) based substrates have great potential for quantitative analysis of hazardous substances using surface-enhanced Raman spectroscopy (SERS) due to their significant signal enhancement, but face challenges like complex preparation, and lack of tunability. Here, we have successfully prepared a well-defined core-satellite superstructure (ZIF-8@Ag) through solvent-induced assembly of silver nanoparticles (Ag NPs) on truncated rhombic dodecahedral ZIF-8. By wisely selecting toluene as the solvent, the assembly process can be easily initiated through ultrasonic treatment and it allows for precise morphological adjustments to build a range of superstructures with different assembly densities of Ag NPs feed ratio tuning.

This short review addresses the pressing issue of lung cancer among firefighters, a population facing unique occupational hazards such as smoke inhalation and asbestos exposure. With lung cancer being a leading global cause of death, the study emphasizes the disproportionate burden on firefighters. Notably, wildfire smoke, containing carcinogenic elements, poses a rising significant threat to firefighters' respiratory health.
