The main properties underlying the reduced fire hazard are the low volatility of methanol and its low-temperature, smokeless flame, as described earlier. A very important, althou not obvious safety advantage possessed by methanol arises because the methanol flame possesses a low radiant heat output, which is a direct consequence of its smokelessness and low luminosity. This is a significant benefit, because not only does it allow a closer approach by fire fighters but also there is a much lower probability of fire spreading to nearby ignitable materials, and it is therefore much easier to put the fire out.
