Topic tags/keywords: fire boiled linseed oil rags smolder disposal

After smothering some old barn wood in Boiled Linseed Oil with a staining pad and wiping clean with a nice soft rag I left the garage for approx 2 hours. When I came back to throw another coat on my wood the pad and rag were charred. Where the two fabrics had touched the oil had combusted and a small fire had begun and then thankfully self extinguished. The whole rag and pad weren’t ash, but it was a nice crunchy wake up call to just how little it takes to do potential damage.
OK, so question… What do I do with all my Linseed Oil soaked things? I know metal can full of water, metal lid and then what… Do I throw this stuff in the washer or dry it out somehow ? I love using the oil, but am I filling up landfills with old paint cans full of water and rags? The directions on the back just leave you with a metal container full and closed and I think there is a next step they have failed to provide.
What do other people do with theirs? Thanks.

I too just hang mine to dry and toss them but I make sure I hang them on something metal away from all other combustable items.
I read a story in The Mother Earth News one time about these folks who built a nice cabin out in an open wilderness area. When they finished coating the outside with linseed oil, which I understand you can properly do, they hung the rags on the porch rail and went about their business. In the sun laying on the newly oiled wood the rags combusted and burned the whole cabin to the ground. They were so far out in the wilderness that they couldn’t call the fire company even if they were able. Total loss, aboslute devistation seeing all your months of work go up in flames.
In industry they use a closed covered container for oily rags, less circulating air and if they do ignite they will burn out quickly.
You were lucky, be safe.

BLO has no other use than starting fires. Whenever I use an oil based finish, I dispose of any tainted rags in a lidded coffee can that’s partially filled with water.

I use a ziplock type bag half full of water to soak all contaminated rags or applicators. At the end of the finishing project, the excess water is drained and the headspace air is squeezed out. The entire bag with the water wet stuff is thrown away.

My shop is in my garage with a concrete slab. When I use any oil based finish, I lay the rags and such out on the garage floor and let them dry. Lay them out flat so they can dry easily. Folds and crumples are what start the fires. If you are insistent on using the staining pads, I suppose you would need a metal container. I just use old t-shirts that I fold over several times.

katilicous,

Thanks for posting this question! It is a wake up call/reminder, that needs to be aired.

I knew about the possibilty of combustion, but it slipped my mind, just how easily it can happen. I suppose I lucked out, as I did spread my used rags (t-shirts) out to dry. However, once out of sight, thay were also out of mind! NOT neccessarily a good thing. I think it is time to (re)address general shop safety procedures & practices.

My question for folks that let them dry. Do you dry them indoors or outdoors???

Again, thanks for asking your question. It just possibly may save someone (many) life & home, literally!!!

I dry my blo soaked rags by hanging them over the edge of a galvanized trash can. They are unfolded and a single layer. Usually they will be dry in a day or two, but will be left hanging until trash day when they are thrown out. I am always open to better and safer ideas.

I dry them indoors, in the middle of the garage slab, with nothing around them for several feet. If you lay them out flat they cannot insulate themselves and reach a high enough temperature for combustion. Even better than my way would be to have some sort of metal folding rack where they could get air from both sides.

If you are really worried about it, you could get a pedal bin that is made just for this.

I am not a fan for the home shop though. I prefer to lay them out and let them dry. Once they are dry, they are inert and you can dispose of them however you wish.

Love the pedal bin (know I get the reason for these in shop) and all the feedback. What I’m getting from everyone is that laying them flat single layer will remove some or most danger until they are dry and then they wont combust.
once they dry can they be reused? Thanks for all the input

If you lay them out in a single, unrumpled, unfolded layer and allow them to dry on an uncombustible surface away from other combustibles, you have removed all the danger of spontaneous combustion. Then you can dispose of them as you would anything else. Once they are dried, they are crusty and stiff so I do not think I would attempt to reuse them. I suppose it is possible, but rags are cheap.

I put them in a metal container and light them on fire in a safe location, then throw the ashes away. They cant light on fire twice! nah just kidding (hehe)

Hang them, dry them and toss them. Don’t burn your shop downm and stay safe in everything you do.
