They forgot to CLEAN the mold...
There's debris in it, and that stuff doesn't seem to like the heat, either.
and the extinguisher, is that Halon or a 'no-hal' system?
doesn't look like CO2, at least.
Not crtain what would be worse...
(Not an expert. Halon/No-hal systems doesn't cool down stuff, only replaces the oxygen. CO2 will cool the stuff, but is that really something you'd want to do when working with molten metals?)
Why the F! aren't they working on a properly fireproofed station?
