    Ever wondered what kind of crater a road going LPG tanker would leave behind?

    Not much. You need a stochiometric mixture of gas and air. By the time the gas leaks and disperses to the right point and ignites, it's outside of the container. You'll get a wonderful fireball, but no strong explosion per se.

    There was a tanker fire on the M56 a year or so back, the tank was filmed venting and the plume was a spectacular jet of flame; but that was a controlled vent.

    An uncontrolled rupture would be a different kind of bang.

    Like LPG cylinders they are designed to fail safe and not get to the "bomb" point - but even an uncontrolled rupture would be a BIG fireball if it was significantly above its boiling point -
    it flashes to gas which the n burns explosively - Google "Boiling Liquid Expanding Vapor Explosion" or BLEVE for youtube videos for what happens!

    Not quite the same thing, but numerous years back on the s/b M1 at Sheffield, an artic tautliner stopped during the evening rush hour, just before crossing Tinsley Viaduct at junction 34 when one his trailer brakes caught hold and set on fire. As is the norm, the entire trailer soon went up in flames, and the load? Yep, aerosols!!

    The east end of Sheffield was paralysed as all the roads in the area were shut down due to aerosols exploding through the trailer curtains, which I sat watching from the yard of the company I drove for at the time. It wouldn’t (shouldn’t...) happen nowadays with the advent of EN 123642 XL “load bearing” curtains, but it was a damned impressive sight at the time.

    We use HF for chemically cleaning the internal surfaces of power station boilers. It's very efficient but it does make life interesting!

    And potentially shorter.

    HF is used in canning plants for cleaning/etching the aluminium cans before printing, probably improves the flavour of the beer.

    People. For various reasons, I haven't really left the house except to do a couple of evening things since early December. Decided to do a quick round trip to pay cheques into bank, pick up prescription and do some food shopping. I had forgotten that the world is full of people and none of them can drive, walk round a supermarket or look where they're going. Back into my nest for another 3 months.

    As far from the sea as we could be, except when we can actually get in it.

    I was thinking along the same lines today. It's no wonder the roads are chaotic when there are a great many people who can cause others so much hassle with a simple supermarket trolley.
