Or even the result of an encounter with The Devil. We use cookies to help provide and enhance our service and tailor content and ads. This is consistent with the theme of the current chapter, as is the categorization given by Taveau [2] of ignition sources for dust explosions occurring in Germany during the period 1965–1985: Although Taveau [2] uses slightly different terminology, his preceding listing is similar to that given by Abbasi and Abbasi [1]. The specific area of a combustible substance is a measure of the surface area of the material exposed to an oxidizing atmosphere per gram of material and is expressed in units of cm2/g. ), Sam Mannan, in Lees' Process Safety Essentials, 2014. Rolli would suggest that a combination of factors was likely at work. A report by Richardson and Ham (1996) outlines several incidents of spontaneous combustion in Queensland underground coal mines. The Victorian explanation that alcohol rendered the body flammable doesn’t work either, seeing that the concentrations of alcohol in even the most intoxicated people are much too low and that an external source of ignition would be required. For example, what are the possible ignition sources for a dust fire? Is spontaneous human combustion real?Learn about whether the phenomenon of spontaneous human combustion actually exists.Encyclopedia Britannica Inc.Now for the important question: Is spontaneous human combustion real? Satisfied, whatever it was, this was the source of the smell and the smoke, he went upstairs to the room directly above where he was – the bathroom. Fault tree (left) and event tree (right) for identifying hazards and assessing the risk of self-heating and self-ignition of coal stored in underground silos. The application of water spray and surface active agent is useful for the control of spontaneous combustion. We publish books on both Kindle and paperback. Nor was the car engine running at the time, meaning an electrical fault was also unlikely. Perhaps one of the most famous cases of spontaneous human combustion – if only because the picture of his remains is generally the first image that comes to mind for most of us – is that of 92-year-old retired physician, Dr. John Irving Bentley.

Considering the high temperature required to achieve this, it is highly unlikely that this would have happened. Whether clearer thinking or just a simple evaluation of how bizarre the conclusion sounded, the final analysis was eventually altered. } This equation can be inverted to yield the time to ignition as a function of the ignition temperature, the flux and the thermal inertia k ρ C: It must be recognized that in addition to the solid not being inert, both the thermal conductivity and the specific heat are increasing functions of the temperature for most materials. Spontaneous combustion occurred in a copper powder—sulfur mixture used in the manufacture of brake pads. The following are just a handful of some of the initial reports of spontaneous human combustion. The lawyer would offer that Nicole Miller was almost certainly a victim of the phenomena known as spontaneous human combustion. Perhaps most intriguing of these findings of the very early nineteenth century, was that the use of water in such circumstances would “fan the flames” as opposed to putting them out, and even stranger, at least according to Lair’s research, most of the victims were women. Spontaneous combustion often occurs in piles of hydrocarbon-soaked (oily) rags and can constitute a serious fire hazard. Measures to prevent explosion and fire during manufacturing and handling of explosive materials (article 256). Although the incident wasn’t ruled as spontaneous human combustion, the official conclusion was an “open verdict”. Some classic examples are oily rags and high piles of coal. What made the death of 76-year-old, Michael Faherty stand out even more than the strange circumstances around it, was the fact that it was the first time, in over a quarter of a century in his position, that the coroner, Dr. Ciaran McLoughlin, would rule the death was officially due to spontaneous human combustion. However, these theories were largely dismissed, largely due to there being no sign of any type of accelerant being found on the remains. Alien-Human Hybrids – Pure Nonsense? When his neighbor, Virginia Cadet, rushed over to see what the shouts and screams were, she was shocked to see the elderly Sik Kim with blue flames covering his entire body. There was no evidence of foul play. Did they simply shut down the investigation so quickly, and seemingly unsatisfactory, due to it being in an area they had no knowledge of? It is indeed a truly scary and unnerving thought that one could quite literally burst into flames at any given moment. A pyrophoric substance may be a solid, liquid, or gas. High ambient temperatures also reduce the rate of heat removal, bringing the hydrocarbon closer to its ignition temperature. He has been writing and researching with over 20 years experience. Can you see possible uses for this technique in your own hazard identification and risk assessment efforts, both in general and specifically in relation to dust fires and dust explosions? The death, or more to the point the reasons it occurred, remain a mystery. Further details are given in Ref. Where, then, did Dickens, who like any fiction writer would have researched such topics before incorporating them into his work, get such an accurate description of a spontaneous human combustion incident?
