I don't know about life-threatening...
But when I "explode" rocks using Ohm's law, I reach temperatures a bit over 1100 degrees locally.
And the material that most easily and cheaply retains the heat and transfers it into the rocks is, in fact, mineral wool in at least a 15cm layer.
And one thing is certain, it smells terribly from the gases emitted, and you're guaranteed to get a headache and stinging eyes in a fairly short time!!
The wool can't withstand these temperatures, meaning it melts locally where the heat is highest.
So sure, there's definitely something wrong about it...

Sure, if I'm doing something bigger, I wear a mask. But a couple of weeks ago, I just needed to make a small cut for VP pipes in old insulation after opening up a wall... and I didn't think a mask was necessary then, but sure enough, I felt it.
I know that mineral wool is not like asbestos. But you can't help but think that not so long ago, both asbestos and smoking were considered harmless...

This is exactly what I mean. There is something dangerous.TorpAnders said:
Exactly what you mean? That mineral wool becomes dangerous at 1100 degrees? If you have read Pasta's post earlier, you get an explanation of what happens when the insulation is heated.
If you have a problem with it in your house, then you also have a problem with the house being fully on fire.

You don't want to upset a forum god but!.jon_h said:
Do you know what happens when you throw insulation in the dump? What do you think they do with it?
What do you mean by "getting upset"? This is the second time someone makes a snide comment about the "Forum God" title. Do you think I wrote that title myself?
I thought it was about the health hazard of having mineral wool in the house. If they burn it at the waste facility, which I assume you mean, it doesn't automatically mean it's hazardous to health or the environment. There are plenty of substances that would be dangerous if inhaled directly in high concentration, but when purified in incineration plants and/or diluted in the air, they are completely harmless. Monoisocyanates belong to these.

It feels like the simplest solution is for you to completely refrain from using mineral wool, Juvefarmer. It's a freedom we still have in this country.
Personally, I've probably never had 50 degrees Celsius in the house, let alone 190 degrees or 1000-1100 degrees, so I must say I'm moderately concerned.
To be honest, it feels a bit like the issues with electric allergy; many of us have electricity at home, but few suffer problems because of it.
If you don't trust a material, there are alternatives, aren't there...
Best regards,

Why do you think they burn mineral wool at the dump?juvefarmer said:
Mineral wool does not burn and would require a lot of energy to melt.
Mineral wool is recycled if sorted correctly.
There are even specialized companies in the area.

We have received an account of what happens when mineral wool is heated, what new information is in the report (which you have read but still find exciting to see?)
I know what happens to the mineral wool I throw away at the dump. It ends up in landfill since it is non-combustible, along with ceramics, gypsum boards, etc. This, of course, can vary between different municipalities and how they have chosen to handle their waste. Considering the amount of mineral wool that is incinerated in that way, I probably wouldn't be worried. A regular house fire would likely generate more such gases than waste incineration does.
Bakelite, which constitutes the binder in mineral wool, is a known material that I would assert they should have identified the issues with by now. The other component is glass, and if it can't withstand 50 degrees heating, do you not wash your glasses in the dishwasher either? At least my dishwasher reaches 65 degrees.
