Or if it was another process that ended up creating molten metal (like a battery fire of some sort).&lt;p&gt;Given the hydraulic fluid mention I was also speculating that a gigapress might be involved.&lt;p&gt;Like everyone commenting I am always amazed at exothermic events that can&amp;#x27;t be put out by water or CO2. The only one I&amp;#x27;ve ever seen &amp;quot;in person&amp;quot; (other than the obligatory set some magnesium on fire in chemistry) was a halon dump on an IBM System 370 when the water coolant system burst a pipe and shorted the many bus bars. That one triggered a 15 second siren followed by a halon dump. I found it quite exciting, the plant manager, not so much.</text><parent_chain></parent_chain></comment><story><title>CA crews handle tricky fire at Tesla factory</title><url>https://www.firehouse.com/operations-training/news/21214084/ca-crews-handle-tricky-fire-at-tesla-factory</url></story>
