Whis work presents a study on the flammability of epoxy coatings containing two types of nano-scale fillers as potential flame retardants: expandable graphite (EG) and halloysite nanotubes (HNTs). Both nanocomposites are prepared by incorporation of the same amount of nanofiller into the epoxy resin for the sake of comparison. Fire retardant nanocomposite coatings are cured through a two-stage ...

This manuscript shows how the connection and interaction between a process dynamic simulator and a dynamic accident simulator allow improving operators training, accident investigation, and safety management, by better modeling the feedbacks existing among process units and accidental events. In this perspective, the manuscript presents a rather simplified case study that allows simulating the ...

There is an increase in the incidence of intraoperative fire in Indian hospitals. It is hypothesized that oxygen (O2) enrichment of air, is primarily responsible for most of the fires, particularly in intensive care units. As the amount of ignition energy needed to initiate fire reduces in the presence of higher O2 concentration, any heat or spark, may be the source of ignition when the air is ...

Electrical fires—fires directly caused by the flow of electric current or by static electricity—are one of the important types of structure fires. The subsequent development of an electrical fire is generally no different than that of any other type of structural fire. But the mechanisms leading to ignition of an electrical fire are, in many cases, uniquely specialized and in need of specific r...

A theory of the Hindenburg fire that has gained popular acceptance proposes that an incendiary paint covered the outer surface of the airship. Further, according to this theory, the paint was both the point of ignition and the sole cause of the rapid spread of the fire. The hydrogen within the airship is held blameless for both the start of the fire and its subsequent advance. We have examined ...

Wildfire simulation modelling was used to examine whether fuel reduction treatments can potentially reduce future wildfire emissions and provide carbon benefits. In contrast to previous reports, the current study modelled landscape scale effects of fuel treatments on fire spread and intensity, and used a probabilistic framework to quantify wildfire effects on carbon pools to account for stochas...

An experimental study of ignition risk due to hot points in the storage of bulk materials is required to ensure fire safety. Many parameters are involved in this phenomenon: nature of the material, storage volume and temperature, type and size of hot point, etc. The aim of this study is to determine critical ignition temperatures of hot spots embedded in powder materials for different condition...

The emergence of ignition device of semiconductor bridge provides a way to resolve the conflict between low energy and high promptness, reliability and safety of initiating explosive device. But with the rapid development of arms and ammunition, the higher demand of miniaturization for structure and volume in design of initiating explosive device is put forward based on high safety, reliability...

Fire is a key factor controlling global vegetation patterns and carbon cycling. It mostly occurs under warm periods during which fuel builds up with sufficient moisture, whereas such conditions stimulate fire ignition and spread. Biomass burning increased globally with warming periods since the last glacial era. Data confirming periglacial fires during glacial periods are very sparse because su...
