message: Question: where is the heat when a gas oven lights from a spark? This seems to be a common case which the triangle is insufficient to explain, since no fuel, oxidizer or heat has been added. Neodymion (talk) 16:38, 6 July 2009 (UTC)
replies: text: Sparks are usually pretty hot. Visible sparks from a flint are particles of metal that are hot enough to incandesce, and visible electric sparks are a form a plasma with energy equivalent to a few thousand degrees. DMacks (talk) 16:53, 6 July 2009 (UTC)

message: Question: pressure is only described to be a possible contributor to activation energy; but I've found no examples or research indicating that fire can start without pressure, or continue without it, and some to the contrary. Is this simply something that has been excluded because on the surface of the earth pressure is ubiquitous? Or is there some other more compelling reason for the omission? -- thismatalk 19:37, 3 March 2017 (UTC)

message: The article talks about the energy release of a fire, giving an example of "up to 7.550 calories/kg for aluminium". But the Standard enthalpy of formation of Al2O3 is −1675.7 kJ/mol. The molar mass of the oxide is is 101.96 g/mol and the atomic weight of aluminium is 26.982 g/mol, so by hand-waving math:
:(-1675.7\frac{10^3 J}{mol Al_2O_3})(\frac{1}{2*26.982} \frac{mol Al_2O_3}{10^-3 kg Al})(\frac{1}{4.184} \frac{cal}{J})=-31.052 x 10^6 \frac{cal}{kg Al}
Even if "7.550" is really a European thousands separator, the value and order of magnitude seem waaaaaay off. Anyone have a direct cite? DMacks (talk) 15:05, 5 April 2017 (UTC)

message: The need for fire to have heat to begin or continue seems less obvious than the other two. Fuel and oxygen are components of the chemical reaction, but heat does not appear to be. 
Can someone add an explanation to the statement "Without sufficient heat, a fire cannot begin, and it cannot continue."  — Preceding unsigned comment added by 49.178.25.210 (talk) 10:08, 8 July 2017 (UTC)

message: Hello, I am a student at the University of Oregon. I am taking a fire and natural disturbance course and would like to help on this page.
In Fire triangle, I would like to add to the description of what is a fire triangle and add the fire diamond and use the resource of our class text book. I would like to elaborate on the idea that the triangle can change as space, size, and time of fire progresses. As the size of a flame moves to wildfire with addition of more oxygen the fire grows by production of weather and climate.
