Aircraft Toilets - Safe

Posted (8 months 3 weeks 5 days 8 hours ago) and read 5850 times:

I have often wondered what would happen if someone sitting on an aircraft toilet pushed the "button"? (whilst seated)

Would the suction cause them serious injury, (as say has happened before with swimming pool skimmer boxes), or is there some sort of safety device to prevent this happening?

Strange topic for sure, but I would be interested to know.

I could have gone the rest of my life without that mental image. But, thanks to a.net, I can now have that terrible picture scarred into my mind forevermore.
And to think, some of the newbies PAY for this service?!!

Why would you just try that? This is why you get obvious warning signs on stuff and you wonder who on earth needs them.

As far as I remember, an obese woman got stuck on a SAS B767 on trans-atlanitc flight for that same reason and had to spend the rest of the flgiht in the toilet but don't remeber how many hours were left.

Why not? I was curious, one of humankind's best traits! Also I was aware of the Mythbuster episode where they proved it isn't dangerous. If it actually was there would already be a warning sign, now wouldn't there?

Why, because I don't do stupid, irresponsible things? The best thing that could happen to you was nothing, which is hardly fantastic. At worst, you damage the toilet or yourself. Hey, if that's what you consider a smart thing to do, have at it. Don't let me stop you. If you also think the best way to find out if something is dangerous is to just try it, sooner or later you won't be so lucky.

I think this has been discussed and debunked before....its a myth. There is virtually no way that you would cover the entire toilet bowl when you sat down and as such there is no way a suction could be created to keep you stuck on the bowl. The most that would occur is a bit of ehemm.....flapping.

I would think that after sitting in a plane for several hours, that might actually be rather refreshing.

Don't tell MOL, he'll add a toilet flushing fee.

Well, with some of the Persons of Size, I think a few could cover the entire toilet bowl. But I think there is a small air gap between the seat and the toilet rim to prevent any suction.

I first heard that woman stuck on toilet joke years and years ago. The original story had a TW 747 are the culprit and it happened in SFO. I remember reading something about fireman had to come on board to rescue the woman while they released the pressure in the system from below. Also remember in the article said the flight attendant gave the woman a blanket to cover her bottom half because "due to safety regulations" the bathroom door had to be held open for landing by a flight attendant in the jumpseat right next to the bathroom. I think the aircraft in question was a 727 instead of a 747. But that's all I remember about it.

But after extensive Googling looking for this incident, I came up with nothing. But there were other stories about the same thing using various airline names.

That had to be a fake, since neither TW's 747 (the -100 or the -200 versions) not the 727 were equipped with the pressure toilets.

Like I said this story has been going around since the 70's. I don't think it's real. It makes just that, a good story.

Thanks guys, for the very funny and interesting comments.

However it is a serious subject.

What happened in the swimming pool skimmer box accidents is that someone what sit on the round opening of the skimmer box with the lid removed, and thus accidently form a good seal. The pool pump would continue to work, and the vacuum pressure inside the skimmer box would continue to increase in the negative and eventually the bowel is sucked out through the anus, resulting in serious injury. This is not imaginary it has happened.

The law here, now requires designs where this cannot occur..

If some person with a large butt sat directly on the steel rim, with the (seat lid lifted), and formed a good seal, and pressed the button, would the negative pressure be sufficient to do this or is there some kind of negative pressure limiting device, or a design feature, such as a vacuum vessel with limited capacity, without enough potential vacuum to cause injury.

I actually thought that an FA may know this as part of their training.

Hence the reason why Mythbusters tested it. This was in their early days when they actually tested urban legends, not just random idioms, YouTube videos, Discovery Channel show tie-ins and anything where they can end the episode by blowing something up.

Anyway, they couldn't get anyone stuck to the toilet, as I recall, even with an unrealistic amount of suction. There's just no way to form a perfect seal. Even the most obese person is going to end up with a little air hole between their legs as well as their butt.

I'm a rather fat guy. Well I'm really fat. I'm 6'2" 330lb. I also was a flight attendant for Shuttle America. 2007-2009. I can tell you. On a ferry flight, I plopped my rather large figure down on the toilet (E170), closed my legs. Made sure there was no gaps and hit the button. Yes we had suction toilets. I did not get stuck. Maybe on older aircraft there may of been issues, but on the newer planes, uh uh ain't gonna happen. If it didn't happen to me, it isn't gonna happen to nobody. BTW those toilets can suck a whole roll of TP from the FO's seat all the way to the aft toilet in one flush, that's pretty cool.

As if there was anything wrong with that. We need to come up with a myth about an exploding aircraft or something like that.

This is actually true. Australian Standard AS 1838:1994 Swimming pools - Premoulded fibre-reinforced plastics - Design and fabrication actually contains the following warning:

Warning: When considering the arrangement of the skimmer box, special care needs to be taken to ensure that young children are not tempted to sit on it or on other filtration system suction points. In the past, this practice has lead to serious injuries and, in some cases, to death by disembowlement. It has been shown that a removeable cover does not provide sufficient protection against this kind of accident.

However given the level of though that goes into safety system on aircraft, would they really design a toilet that was dangerous to passenger? Never in a million years. Also swimming pool pumps work on a constant basis whereas aircraft toilet systems pump for just a few seconds at a time. That said, given the sheer number of people flying and therefore using aicraft toilets (an ever increasing number of them falling into the larger category), I reckon there is a outside possibility that some freak and unfortunate combination of circumstances were someone finds themselves in an embarassing situation where they do get sucked to an aircraft toilet bowl.

It's impossible on the 787. If you leave the lid open, and hit the flush button, the lid will shut before the toilet actually flushes.
