While many a stiff rag has been made from the after effects of some friction, thankfully the inclusion of boiled linseed oil in the mix seems to be rare.
My experience comes from doing a transmission change and leaving atf+4 soaked jerry rags on a concrete driveway in the Arizona sun, lots of smoldering and burn holes all over
Have you tried brake fluid and the red or blue shop rags? They always seem to get warm within an hour piled 3 or 4 deep on the floor. When I would pick them up I would notice the temp and rinse them in water before putting in the rag can. I never felt engine oil or grease rags get noticeably warm and always wondered if it's the brake fluid that sets things off.
Im a little paranoid, if I have solvent laced rags, I toss them over a beam in my back yard until they dry guy. I remember a couple times when younger that I unfurled some solvent rags and they were abit warm when I dug them out of the can..
Greenhouse effect with no moving air…. Works every time… side effect of construction sights are that all the hvac is typically off to avoid pulling sawdust into the system
I am just waiting for the AvE and Internet Historian collaboration. Listening to AvE's slang and lingo and mis-terminology to go along with the Internet Historian would be a wild trip turned up to Shmifteen.
There is an osha proved container you can buy for this. Rely it's just a can with a lid to smother any potential fire, no oxygen means no fire. The osha proved bin is designed in such a way that there are no holes to ventilate the containment area, but pretty much still just a can with a lid.
In some very old video you talked about it, you said that what would happen was that the crystalisation of the oil nto the hardened stuff compressess so hard that the friction of them is what causes the temerature rising, while i know you said it, because my mind works that way, i dont know when, and i dont intend to find out, because my mind works that way too
I nearly burned my garage down with linseed covered rags. I was using a product which is essentially linseed oil mixed with paint thinner for rustproofing a car. The manual clearly stated not to throw the used towels into a trashcan but to hang them up oder lay them flat on the floor. Naturally I did not read the manual and threw them into a trashcan around the corner. When I was about to leave hours later, killing the lights I noticed that strange fog hovering around an emergency light and was like "what?!". As soon as I opened the shop door to kick the smoking trashcan out it ignited. I don't think I've ever moved that fast ever again running to the can, grabbing it and throwing it outside. After that I did read the manual.
Okay guys, a little bit of high school science seems called for here. The three things you need for combustion are? Oxygen Fuel Heat source (high enough to reach the particular fuel’s combustion temp) Some oils cure/harden/catalyze by molecularly combining in an exothermic (heat producing) reaction. If enough of the reacting material is concentrated in a small area where it produces a positive feedback loop of increasing temperature accelerating the reaction process and resulting heat accumulation , especially in an oxygen starved environment, then you come in and disturb the stagnant air so that oxygen reaches the reaction zone, you’ll probably get combustion.
Just had it happen this last summer. Was staining some wood. The stain used linseed oil. Left the rags lay out in the direct sunlight. They didn't catch fire because we caught it. But, I'm sure if Left unchecked they would have. It was a dark walnut stain. Can't remember the brand of stain though.
In maritime enviroment oily rags have to stored in closed container to prevent spontaneous ignition. Probably higher temperature of the engineroom, vibrations and movement of the vessel increase the risk.
Knuckle draggers where I work didn't get training of any type by their department manager and were SHOCKED to discover that peroxide and sodium hydroxide soaked soaked trash (in a plastic barrel)… catches FIRE! Luckily calmer heads prevailed and stopped an inferno type disaster. First responders and I all had a good chuckle after the flames were out. State and federal safety investigators had no sense of humor.
As you indicated in the first video, the modern boiled linseed oil has a chemical drying agent within it. Unlike other common wood finishing oils like walnut oil or Tung oil which dry very slowly by evaporation of volatile components, boiled linseed oil dries by chemical oxidation which is exothermic. Hence, enough oil-soaked rags in close proximity will chooch. Now that I'm living out in the country, I'm gonna have to post a video of this on my own channel I suppose…since I already have all the ingredients on-hand.
FYI, the safe ways to handle oily rags like this is to either discard them into a safe, enclosed flammables container, or if you don't have one of those, like myself, completely unfold and flatten out the oil soaked rag and leave it on the floor by itself. I've done the latter several times without incident whenever I've used boiled linseed oil in the past.

I wonder about linseed oil and fine sawdust.

That’s a whole lotta hotel pool towels you got there ehh?
When I was 20 I worked in a auto shop and watched as a open pall of oily rags caugh fire from the sun hitting them though the window
Hell yeah . Jewish lightning ⚡️ ⚡️

Try some wood dust. A lot of wood work is around that kind of oil.

The worlds worse accidents happen when there is a 99.9% success rate.

Thought that was a pile of my underwear for a second. Wiping is a recommendation not a rule.

Increase the surface area, you need more oxygen. Try cotton waste!
It’s kinda like my dad used to say, “The insurance wire got to rubbin’ against the payment book”.
Real Jews don't care. I was named after King David, so take my word for it.

would it make a difference if the rags were compressed into a bin…

Maybe a trip down to ye old hazard fraud for a fresh pack of chinesium cotton rags would suffice, no way they wasted money on bromine for those….
The lightning though…. the "lightning" 😅 Insurance, mortgage… Lightning! 😂
I would like to point out science is just messing around and recording any information you may find
I think they call it a Jewish stocktake
I’m not holding my tongue for another’s feelings.
Oily rags dont catch fire themselves. Lol if they dis every mechanic shop would be ablaze.
I've seen dish towels out of a drier catch fire when placed in a pile.
Of course, they were already hot.
