Reversed polarity

[maingate]

How many motorhomers have been found dead in their motorhomes after being gassed during the night by thieves? If none, the gassing thieves have been extremely fortunate or extremely skilled.

I am merely putting forward an argument that it would be possible to administer a form of gaseous substance which could deepen the sleep of someone. If someone is tired anyway, a tiny amount would be enough to do the job.

Perhaps it is not gas at all. perhaps they play a CD with Whales calling, or waves gently lapping on a tropical beach.

If you take a gas such as Carbon Monoxide, an amount of 1.28% and (therefore) 98.72% Air is enough to cause unconsciousness after just 2 to 3 breaths, followed by death within 3 minutes.

So can someone tell me how many HGV Tanker loads it is equivalent to? Remember this sort of thing normally happens in a domestic dwelling and consequently a much bigger volume than a Lorry Cab.

I believe the statement dismissing the possibility and mentioning tanker loads of gas is a deliberate spoiler to end the discussion.

Volume of air in a motor home = length x width x height to get the e.g. 7m x 2m x 2m = 28 cu meters

Gas at 1 ATM required to fill 1.28 % of a motor home = 28 x (1.28 / 100) cu meters = 0.35 cu meters = 350 litre

Gas at 100 ATM (CO can be stored at over 100 ATM) = 350 litre / 100 = 3.5 litre = under a gallon

I just love Bistro Math.


Carbon monoxide (CO) detectors typically trigger at around 30-70 ppm which is 0.003% - 0.007% and would be activated by under 2 litre of CO at room pressure (or 1/2 teaspoon at 100 ATM)

Are you some kind of psychopathic serial killer?

Yep ......... and I know where you live

I'm not going to post my photo because that would make Dibble's job too easy.

But here is a photo of my twin brother who is in the same line of business.

Are these values correct .
Would be great to see a link to substantiate them.

Don't tell 'im Pike.

Good point!

Volume of air in a motor home = length x width x height to get the e.g. 7m x 2m x 2m = 28 cu meters

These figures are based are "nearest meter" measurements on my MoHo
You can, of course, substitute more accurate measures for your vehicle and even factor a reduction in volume for fixtures and fitting

Gas at 1 ATM required to fill 1.28 % of a motor home = 28 x (1.28 / 100) cu meters = 0.35 cu meters = 350 litre

1.28% is a given in the post asking for amount of CO to be calculated and thus does not need substantiation.

(CO can be stored at over 100 ATM)

Perhaps it is possible to be gassed, but the people who are robbing motorhomes are members of The Royal College of Anaesthetists, and they are trying to throw us off the scent

The Russian security forces who used gas to sedate the kidnappers and hostages in the theatre don't seem to have been members, can't recall how many died, certainly double figures.
