It doesn't lead to death (except perhaps from embarrassment) but it sounds like those interesting cases that hospital emergency wards get occasionally of the guys that slip over while vacuum cleaning in the nude and the nozzle gets attached to a particular private part of the male anatomy.

Kids playing with sprinklers and hoses and sticking the hose in their gobs would be in danger. And it does not matter that it's water or air as high water pressure can cause the same damage. The reality is that those pressures it is physically impossible for most people to restrain the pressure onto their skin - the nozzle has to be mechanically held to achieve that.

Yet from another popular thread, you say:

80-100 psi (~5 - 6.5 atmospheres) isnt really arguing down to 15 decimal places is it? It looks more like a gut feeling to me, but thats ok because its your gut feeling so you need no further convincing. I can live with that.

Theres a sucker born every minute, as Mr Barnham said.

An old girlfriend of mine was an emergency department nurse who dealt with a case of a man who claimed he locked himself out of his house and had to climb in through the window to get back in. but he slipped somehow and a tomato sauce bottle got wedged somewhere that a tomato sauce bottle has no business being in the process. Apparently the lad went redder than the tomato sauce bottle when she asked him to explain why the bottle was wearing a condom.

The other concerns are ears and eyes but presumably you are wearing muffs and safety glasses.

The major concern is for high pressure industrial compressors and fuel injection systems (600+PSI) [QUOTE]

Just as a point of interest and for no other reason modern common rail diesels are now running 15,000 PSI fuel pressures. Don't be tempted to play with one unless you know what you are doing as they are bombs waiting to injure someone.

80 to 100 psi are not my numbers, and as they are only stated to 1 significant figure, restating them to 15 decimal places is metrologically incorrect. Besides, even an interval with start and end points expressed with one significant digit is worth a 1000 gut feels.

Yep these are very nasty because they can do lots of damage even at some distance.

Even a domestic water water jet cleaner cleaner at ~200 psi should be treated with respect - certainly much more that many of the ning nongs that use them. Somewhere I saw a video clip of a woman washing down her kids with one!
