Boeing's Self-Cleaning Aircraft Bathroom Lets You Use Loo Without Touching Anything

coondoggie writes: With barely enough space to um, sit, and with high capacity usage, the commercial airline toilet perhaps is an engineering marvel but little else. Boeing however is looking to that notion with a self-cleaning aircraft bathroom -- known as the Fresh Lavatory -- that the company says uses ultraviolet (UV) light to kill 99.99% of germs in the loo -- and even puts down the toilet seat lid. "We're trying to alleviate the anxiety we all face when using a restroom that gets a workout during a flight," said Jeanne Yu, Boeing Commercial Airplanes Director of Environmental Performance in a statement. "In the prototype, we position the lights throughout the lavatory so that it floods the touch surfaces like the toilet seat, sink and countertops with the UV light once a person exits the lavatory. This sanitizing even helps eliminate odors."

    Sure, it's a good idea to kill of germs with UV light - but that ain't self cleaning. Someone sprinkles all over the seat, and leaves shaving hair in the sink, and you're going to need a lot more than a black light bulb.

    Sounds like this is a PR stunt to make passengers happy, without doing much on their end.

    I do wonder how all the plastics in the room will hold up with the extra UV light.

      It depends on the surfaces being exposed to UV. Surfaces with titanium dioxide in them do tend to be self-cleaning.

      I liked the self-cleaning crappers in gas stations on the German/Austrian Autobahn. The seat is circular. As soon as you get up off it, the toilet flushes; a mechanical arm swings down with a sprayer and a brush; and the sprayer shpritzes and the brush spins while the seat rotates 360,

      There is the issue about someone being in the bathroom. A small kid that the IR sensor doesn't detect, someone accidentally tapping the "door closed sensor twice", or other items... UV lights come on, and now the airline has a big fat lawsuit on their hands.

      Look at toilet sensors and how relatively inaccurate they are. Yes, they tend to be OK to not spray water on you in general, but cataract-causing UV light isn't something to be considered "good enough".

      If you didn't have those cataracts, you'd have been able to read the (short) article:

      The lavatory uses Far UV light that would be activated only when the lavatory is unoccupied. Far UV is different from the UVA or UVB light in tanning beds, and is not harmful to people

      UVC at 100-280 nm encompasses the entire "Far UV" band of 122-200 nm. And UVC is, perhaps the most dangerous of all the UV bands, and that's precisely why it's used for sterilization. It's germicidal, mutagenic and carcinogenic.

      UV lights used in many public toilets and back alleys in the 80s[*] were banned many places, because of the harmful effects.

      [*]: For the multi-purpose of:
      - Mild sterilization.

    And thus how Aircraft bathrooms get in the state they do - everyone tries to use them without touching anything.

    The first users, when the bathroom is clean, probably don't do that. It's when a bathroom starts getting untidy that a self-reinforcing feedback loop takes over. The dirtier the bathroom gets, the more successive users make it exponentially worse.

    Some airlines, particularly Japanese and Korean ones, have the flight attendants put on rubber gloves and clean up the bathroom periodically mid-flight. It's a bizarre concept, I know, but it seems to be a good solution.

    Soap doesn't kill germs. All it does is makes oily substances more likely to be pulled along by water than they were before.

    Soap certainly kills some germs. There are lots of bacteria and viruses which are vulnerable to the SDS (sodium dodecyl sulfate), a detergent widely used in hand soaps, shampoos, and a bunch of other sudsy consumer products. The detergent disrupts the cell membranes of many bacteria, and it denatures (unfolds) important proteins in many strains of viruses and bacteria.

    Sure, the improvements to mechanical cleaning and suspension of oily matter are important, too. And there are certainly some things (spores and other more robust pathogens) which are resistant to SDS and other detergents, particularly at short exposure times. But "soap doesn't kill every germ" is a long way from "soap doesn't kill germs".
