The Maritime Sikh Society says both the victim and her mother were employees at the Walmart in Halifax. The mother remains in shock, the organization says.
Yeah, the only way someone is dying in a furnace before feeling pain is if you’re dealing with molten-metal-type temperatures. Not a bakery oven. I’m sure this poor woman experienced excruciating pain for far too long.
Heat up a frying pan on low heat and throw some water in there. It sizzles and bubbles weakly but evaporates quite quickly.
Now heat up the pan over medium-high heat. Throw water in there and watch it turn into little marbles that dance around the pan. It seems much more violent but notice that the water marbles last way longer because they’re actually floating on a cushion of steam. This is also why they seem to fly around pan so rapidly: the steam cushion removes almost all of the friction.
This is called the Leidenfrost effect. Very high temperature frying pans actually conduct heat into the water more slowly than lower temperature ones because the steam cushion acts as an insulator.
Well it turns out if you put your hand in molten metal the same thing happens! The moisture on your skin flashes to steam and creates a barrier which slows down the conduction of heat into your skin. Of course, if you fall into molten metal you may not be able to get out. The Leidenfrost effect also doesn’t do anything to protect you from the intense thermal radiation being emitted by the molten metal!
Funnily enough, this also happens if you pour some liquid nitrogen into your hands. It dances around just like the water does in the hot frying pan. Your skin is like a hot frying pan compared to liquid nitrogen and the nitrogen gas produced is like steam in this case.

I work at one of those furnaces, if you fall in molten metal it will not be fast. You are EXTREMELY buoyant in liquid rock/metal.
Absolutely terrifying… but thank you for the insight.
I think about it a lot while staring down into ‘The Pit’ on the production floor.
