      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Cutting up and scrapping furnace oil tank: Explosion worries?

Recommended Posts

I've got a 250 gallon fuel oil tank in my basement that's no longer used (I converted to propane).

I want to haul it out of there, but the stairway/door is too small to take it out intact (it was brought in decades ago through an outside stairway that's been covered by an addition foundation), not to mention it's a heavy humper. I'm thinking about drilling a hole at the lowest point in the tank and letting whatever small amount of diesel oil/sludge is left drain out into a bucket, and then cutting the tank into pieces with a recip saw.

For those of you who have done this before, here's my question: Do I need to worry about a spark from the drill bit or saw blade causing an ignition/explosion of whatever vapor is in the tank?

My experiance w/ diesel (fuel oil) is that it is hard to just light. I use it to start brush pile fires and the best way to start it is with a small amount of gasoline mixed with about 4 times the diesel. I would not wory about an explosion but check a MSDS sheet on diesel and see what it's vapor pressure is. VP is what causes fumes and then proceed at YOUR OWN RISK and carefully. BTW...Keep a couple of fire extinguishers handy.

Be careful! If I remember right, a few years ago, someone caused an explosion messing with a fuel oil tank. I think they were trying to do something similar.

I have pumped and cut dozens of OIL TANKS... not gas tanks. Booth in side and out

of the home.

Use a SAWALL with metal cutting blade. Fuel Oil is considered a hazardous material

So who you tell about what you are doing is up to you.

What BJB said about a fire extinguisher is right on. I always do.

Put the tank on end, lat it set for a couple of min. That way any oil left in the tank

will be at one end and cut tank in 1/2. takes about 7 min.

It's a REAL DURITY JOB so be papered for it. Tarps, rages, oil dry.

IMO you should be ok with a sawzal. Keep the blade as cool as you can. There is a narrow margen between the LEL and UEL. This give you a better chance that it will be to rich to explode. BE CARFUL.

Keep the speed down. That'll create less heat and the blade will last longer. In the countless times cutting steel with a reciprocating saw, I've never seen a spark when using a blade intended for that purpose. I have seen sparks when using a wood cutting blade and hitting a nail. I wouldn't be concerned about it starting fire.

I'd be more concerned about it blowing up. In nature fuel oil isn't too volatile. Its once its compressed or heated it then becomes more apt to flash. Fumes are a different matter, I know that because if there a way to make something blow up its happened to me. So far its just facial hair and bumps on the head. An oil tank might just go like a good fart or it could make a sonic boom. At any rate knowing that your project will be exciting and not just a PITA that has to be done.

To be on the safe side you could have an assistant(Chunky)give you a continuous spray of water with a spray bottle. That'll at least keep the blade cool which in turn will stay sharp not to mention suppress any spark that could happen. Just don't electrocute yourself. smile

This is for the most part, the safest way to cut a tank. DRAIN TANK.

Remove the fill and vent pipe from the dank. Make sure you only have two holes

in the tank. Run a hose/pipe from a internal combustion motor (you pick) too

the hole at one end of the tank. Then take a second hose/pipe from the other

hole at the other end of the tank back too the out doors.

You have now filled the tank with CO. (No oxygen no boom) Now cut tank.

This opens up a couple of other safety concerns with CO in your home but

hay no boom right.

I like your idea up in tell the CO part. Venting the tank is a great idea. Using two hoses both going out side and hooking one up to an air compressor would be better. This would work till you make a cut and it starts to vent in to the basement. I would make sure the basement is well vented also. Using positive or negative ventilation, set up a fan (blowing in or out) and have window(s) open on the opposite side would work well.

The CO thing is a old welding trick. It's the only way you can do it cheep.

Using a air-compressor will defeat the purpose of the CO.

No oxygen do BOOM.

Remember the tetrahedron FFII

No fumes no boom. If it’s below the LEL (lower explosive limit) it will not ignite. Remember Hazmat operations. And CO is poisons.

OK,ILL give you that one. (except)

After doing 6-8 tanks a year over the last 30 years. You can't get all the oil out

of a tank... (unless you burn it) GRIN I just don't think you could dilute it enough.

In this case I think the CO is much safer, other then the CO is a hazard all by it self.

With a reasonable amount of venting out a window the risk would be quite small.

If I were doing it for a living and got to charge a lot of money to do it,

I would use Nitrogen. But to flow a 270gal. tank would cost at lest 100 bucks

just for the no2 not to mention the bottles.

I hated hazmat class.

It's unfortunate the in todays time we put education before experience

in the fire service. We lose a lot of good people that way.

ILL get off my box now.

    • That's because this is the cooking thread and not Silly Town. Plenty of whining be-oches to argue with over there all day!
    • You guys must have a nicer wife than I've got. By the end of the day I'm worn out from arguing with her and come here for a break. Seems like the opposite on here sometimes. 
    • Yes, we buy the spray cans of olive oil,canola or whatever. I personally haven't tried fish but with breaded chicken I'm not a big fan. It works great when I make wings and non battered chicken. Just my personal experience.
    • That is a thing of beauty. I am speechless and if you know me........
    • Those are cool but I enjoy the amount of water that mixes with my whiskey when I put 2 or 3 cubes of ice in it.
    • That's why my wife is getting one for Winter Solstice too!
    • Milton’s put 1/8 on your house? Was that the new owner? Mines Miltona, 4 years old and came with either 1/4 or 5/16, not 100% sure but it wasn’t 1/8. 
    • I get what Del is saying to a certain extent. I would never buy a bottle of Pappy for $2000. There's no way that any whiskey can taste 40-50 times better than a $30-$50 bottle. I actually rarely buy anything over $35/bottle but that's just me being cheap. I do like to try the $50 stuff but have rarely found anything that I like better than Eagle Rare, Buffalo Trace or Maker's Mark. Actually one of my favorite Bourbon's is Jim Beam Black for only about $25 a bottle. That being said I couldn't care less what other people drink or what they pay for their whiskey, beer, wine or whatever. If you have a job and make your own money, buy and drink what you want. I don't know if that's true or not but I sometimes wonder the same thing about all the people who claim to like really hoppy beers.
