I'm afraid we have decided that discretion is the better part of valor and we are seeking professional (or semi professional) help.

We may even have - horror of horrors - to pay for it to be sorted.

But thanks everyone for your help and ideas. Some have been imaginative to say the least!

I remember my first contact with an aluminium step ladder. Prior that we had 'Steps,GS', heavy steel, steps on both sides and painted blue. Through age and miss handling they were often bent and difficult to open or close. I would place a set undergo the bomb bay and climb in.

One day they were all replaced with shiny aluminium of exactly the same design. I climbed into the bomb bay. There was a bang and the ladder disappeared from under me as it was caught by the constant wind under the Vulcan.

Trust me, this heavy-duty American thing would require a perfect storm just to wiggle.

I don't think my 26 year old aluminium stepladder came with anything other than a single "caution" note affixed to it. But then again it is so bespattered with plaster and paint it's hard to see any of the aluminium...

No the propellant is CO2.

Something in it definitely ignites with a spark; I used to have a petrol pressure washer that could only be started in really cold weather by removing the air filter and spraying in WD40.

I caught part of a programme about a holiday resort in the Bahamas, I think, the other night. Inter alia, it featured a machine for destroying tubes: they just got fed in and shredded inside the machine. No mention made of hazards of any kind.

I'm amazed no grammar pedant hasn't been along to point out that the heading made the common error of confusing 'flour' a wheat product powder and 'fluor' appearing bright or stimulated by radiation.....

This grammar pedant has corrected that for you.

It's not grammar. It's spelling.

When a thread devolves to grammar VS spelling it's telling

No. He used the wrong word, creating a double negative. That's grammar.

The oil itself burns, not the propellant. Hold a good source of ignition where the spray will come out, push button down and you have a pretty good blow torch. It makes a nice sound too.

Hi Sally

Quite deliberate, I was timing the expected reply. 43 minutes - slow for the grammar police!

Ditto, last month. Fantastic. Until one of the two I installed failed yesterday. Back to Screwfix for free replacement; I'll give it the benefit of the doubt as a one-off problem.

My face is red! I have to plead guilty to failing to notice how I was spelling "flourescent". My (lame) excuse is that I've been baking bread recently and thus have had the word "flour" in my mind! I am impressed that there are people on this unrelated website who are observant enough to pick that up.

The tube has now been changed but the local electrician did have a bit of a struggle to get the old one out.

Hindsight being a wonderful thing, I'm now wondering if the whole excercise was a waste of time. We have several such tubes of 2 different lengths.It had escaped my mind that there are different starters for different sizes of tube and the one I had was the wrong one. When the light didn't work I assumed the tube was the problem. I now don't know whether both items were faulty or just one. Happily the electrician carries a selection of such small items.

Moral - when troubleshooting review all possibilities don't jump to conclusions!

If you check the ingredients of WD 40 you will find its mostly refined Kerosine and it is very inflammable if it is sprayed onto equipment that is operating and sparking at that time.

So are you suggesting that it changes its chemical properties to become completely inert and non-flammable if instead it is sprayed onto anything other than "equipment that is operating and sparking at that time"?

I throw the gauntlet down to a member who can describe the ingredients and initial application of that miracle of miracles: WD-40! Giggle is right out. My face shall fluoresce, my existence exhibit evanescence, and my ice trays show sublimation at such time as the winner steps forward!

Remember: all that's needed for a successful life are duct tape, a hammer, WD-40, some grey paint, and a sense of humo(u)r! Electrickery is optional....

You need a pair of those Dennis Taylor glasses...or maybe wear your bifocals upside down?
