Fire! How the Mir Incident Changed Space Station Safety

As the fire spewed with angry intensity, sparks - resembling an entire box of sparklers ignited simultaneously - extended a foot or so beyond the flame's furthest edge. Beyond the sparks, I saw what appeared to be melting wax splattering on the bulkhead opposite the blaze. But it was not melting max. It was molten metal. The fire was so hot that it was melting metal.

You can’t go outside, you’re in a very small volume, and your escape options are limited. Your survival options are limited. That space can tolerate a much smaller fire than you can tolerate in our home. The pressure can’t escape easily, and the heat stays there, and the toxic products are there as well.
