Which advice ?This lot have not been following their own advice.
Not like politicians, eh?This lot have not been following their own advice.
Is Conservative HQ doing fake Class War memes now?
Better to be safe than sorry.Take off and nuke...etc
I do find it odd though that your figure and that of the manufacturer differ, in which circumstance, I know whose figure I would regard as accurate.
The manufacturers of these gas mixtures include instructions in their Material Safety Data Sheets to store cylinders in a horizontal position for at least 48 hours in an area where the temperature is maintained above 10°C and to invert the cylinders three times before use to ensure the mixture is homogenous, but offer no explanation as to why; the background knowledge of the studies done in gas physics and behaviours has long since faded from our collective consciousness.
Nitrous oxide, which as a single gas liquefies at the pressures commonly seen in a medical gas cylinder, remains solely in the gas phase when part of a 50%/50% v/v mixture with oxygen as long as it remains above its critical temperature (-7°C for a full cylinder at 138 bar [2,000 psig]). The resulting mixture is homogenous above this temperature and will not lose homogeneity during use. It is possible to cause condensation and phase separation of such a mixture by cooling the cylinder below its critical temperature. Temperatures below this point may be seen in many months of the year in Canada. However, by allowing a cylinder to rewarm to room temperature for at least a 48-hour period, preferably in a horizontal orientation to maximize surface area for heat transfer to any nitrous oxide in the liquid phase in the cylinder, and briskly inverting it three times before use, the gases in the cylinder will rehomogenize and consistently deliver the proper proportions of the constituent components.
So, BOC the manufacturer has issued erroneous information on its own product?I'm that bored, I thought I'd find some studies.
The effects of temperature on nitrous oxide and oxygen mixture homogeneity and stability
For many long standing practices, the rationale for them is often lost as time passes. This is the situation with respect to the storage and handling of equimolar 50% nitrous oxide and 50% oxygen volume/volume (v/v) mixtures.A review was undertaken of ...www.ncbi.nlm.nih.gov
After lots of science, it concludes:
Maybe you misremembered and the room was below -7°C
I dunno , there are worse people in the world tbhMe neither, but if I had to choose between Johnson and... anybody else...
It would seem so. Although it's not harmful information, more like erring on the side of caution.So, BOC the manufacturer has issued erroneous information on its own product?
I'm sure there are, but Johnson catching it has made my day. I don't think Bono catching it would have cheered me up as much.I dunno , there are worse people in the world tbh
My mum said she thought Raab had it too but I can't see anything in the news

That should be his job every week.Raab's one job in the last two weeks should have been to sit on the bench at home out of the way.

No he isn't. Don't be a dick.Corbyn now furious demanding coronavirus for the many not just the few.
I've now got this as an earworm.It's not been a shock, not in the slightest after the way he was carrying on.
in theory, Sunak. In practice, probably Gove.Oh shit - who's next in line after Raab ? - Patel ?
Corbyn now furious demanding coronavirus for the many not just the few.
more like "pack" or "nest" or "hive" ...I thought that was the Johnson "herd immunity" plan.

It doesn’t work because coming from a right wing cunt like yourself, it would never be funny. What is funny is how the fuck you've managed to stay on here for so long without getting binned off.I know, ‘twas but a joke - an attempt for a brisk moment of light relief in these dark times.
