Ever noticed how you can be right and wrong, both at the same time?
Like, we all know we should wash our hands – but how about drying them?
Yeah, you say to yourself, as you pull the plug. Bye-bye germs, so long suckers.
Washing is only the start
But what do you do with your WET hands?
Ah, no problem – there’s a high-powered air dryer on the wall.
No touch, nice and hygienic, sorted.
Er, not exactly.
Because that high-powered air gets blown somewhere – and it’s all round the washing area. You can often feel it on a cold day – nice warm air, to take the chill off.
Nice, warm bacteria-loaded air – because not everything got washed down the drain. Some of it’s in the water drops on your hand. Some of it won’t come off with a blast of air. You know how a wet leaf can stick to you? Well, a pernicious bacteria can do the same.
We’re all scrubbers
Yup, to be sure everything comes off needs friction. Which means a towel.
But not one of those cloth towels that gets used over and over. That’s a growing collection of germs – not just yucky, but seriously deadly. Like that kitchen wiping-up cloth for the dishes – double yuck.
Not one of those dispenser roller towels either. The idea is that you get a dry unused bit for you to use – but reality is, you grab the wet bit to pull the roll down, collecting germs on the way. And, sod’s law, it’s probably all used anyway, with no more pull-down left. Deadly deadly.
The best is paper towel. Use once and chuck. (Tweet this) No germs to transfer to anyone – plus you get the wiping action that scrubs off residual germs hiding in the damp.
Conserve, avoid waste
There is, of course, a whole hoo-hah about how many you use. Don’t waste, conserve.
Totally agree. And the best way to do that is shake off excess water before you start. Excess GERMY water – which you don’t want to go spattering in all directions.
This demo by Joe Smith gives you a good lesson on avoiding wastage. But you’ll have to think twice about how briskly you shake your hands outside the basin.
Think hard about the hazards of public washrooms too. The build-up of germ threshold from one day’s usage could be substantial.
Let’s hope the service people are using a Hypersteriliser. Otherwise it will be there till tomorrow, ready and waiting to build up some more.
Hypersteriliser units are supplied to businesses and institutions across the UK, notably the haematology and other critical units at Salford Royal Hospital, Greater Manchester; Doncaster & Bassetlaw Hospital; South Warwickshire Hospital; Coventry & Warwickshire Hospital; and Queen Victoria Hospital, East Grinstead.
The Halo Hypersteriliser system achieves 6-log Sterility Assurance Level – 99.9999% of germs destroyed.It is the only EPA-registered dry mist fogging system – EPA No 84526-6. It is also EU Biocide Article 95 Compliant.
Clean, yes – but with residual germs contained in the water drops.
Which means Phase Two – removing the moisture AND the residual germs.
Where’s the drying doohickey?
If you’re at home, there’s probably a towel within easy reach – a fresh one, because you’re that kind of person.
That’s OK, as long as you only use the thing once. Wiping your hands gets rid of the moisture – and has a certain scraping action that gets a lot of the germs off.
But now they’re on the towel which is already moist and at room temperature. Perfect for germ reproduction, which they will certainly do, doubling in number every twenty minutes or so. Chuck it in the laundry and they’ll get sorted.
But put the towel back on the rail to be used again and you’re setting yourself up for re-contamination. You wash your hands again and a whole load of new germs arrive just when you think you’ve got them clean.
Uh, huh. You’ve gone backwards.
Better if you’re in a hotel of course. Fresh linen every day, so it’s use once and chuck. But have two showers, one in the evening and one next morning, both with the same towel and… you guessed it – you’ve re-germed yourself again.
How about elsewhere? Public places, shared washrooms, lines of loos and hand basins and – gasp – other people.
Keep your eyes open, what you’ll see will shock you. Like around half of everybody busily pushing through don’t even bother to wash their hands. Weirdly, some of them will even look like they’re going through the motions – actually standing at the basin – but not physically doing anything.
Why is this, people all in a rush? The place might be done up nice, but it’s hardly where you’ll want to linger. No plugs in the basins for a start – though that’s a good way of compelling you to use running water.
I don’t wanna queue
There certainly IS an issue with hand drying. If the place gets anywhere busy, like Saturday morning at a shopping mall, there’s ALWAYS a queue for the towel dispenser or air dryer.
Right there could be one reason people don’t wash – they see the queue and stump out of there in a late model huff. Another sub-group avoid the queue by wiping their hands on their clothes. Let’s hope neither of them are going to sit down and have a meal with their hands like that.
Could also be the drying method puts them off. Plus the six to ten steps across the floor to the drying thing with your hands dripping, before you can even start.
The yuck method
It’s dying a death now, but the old cloth roller towel dispenser is still around. You know the one – where you grab both edges of a section previously used by someone else to give yourself a fresh piece, pull down hard and then wipe.
Yes, it gets your hands dry – but there’s a good chance you’ve got somebody else’s germs in using it. And the somebody after you gets yours.
How about a paper towel dispenser?
Fiendishly difficult contraptions to operate when your hands are wet – jamming, bunching up, or refusing to dispense all together. You get your hands dry alright, but usually with a wodge the size of a football before you’ve finished – and requiring a dexterity level at least on par with those amazing technical ladies who solder miniature circuit boards.
But technology’s not finished with you yet, because there’s also the air dryer. Either a weak buzzing machine that does nothing, or a force-feed jet blast from a supersonic wind tunnel. Yes, you’ll get you hands dry if you wait long enough – though it will auto shut-off at least five times before you do.
Uh, huh. Check the floor underneath. A lot of people like you dripped for several minutes before the drying became effective. And have you noticed how humid it always seems to get in there?
A lot of water drops are being blasted off into smaller germ-laden droplets and spreading throughout the room. You walk in to go for a sprinkle – and walk out with a dose of flu.
King of the dryers right now is undoubtedly the triple whammy air blade dryer. Pioneered by the Dyson people, who are all totally brilliant. But again, not designed for someone with dripping hands.
Check the floor of the compartment underneath where you put your hands in though – there’s usually a pool of water. Look at the walls alongside and you’ll see damp squidges radiating out – airborne germ clouds, just like the other jobs.
So what to do?
Lucky for all of us, there’s a guy called Joe Smith who has it all worked out. Shake your hands after washing, then dry them with a single sheet of folded paper. Check out his video on TED – if nothing else, his charisma will have you remembering how to get your hands dry safely for ever.
Joe’s mantra is SHAKE your hands to get rid of the drops – then FOLD the paper to give you enough absorbency to remove the moisture. Try it, it works – big time.
But there’s still the problem of acquiring your piece of paper in the first place. Joe has them all primed and ready. But you will have to battle with some kind of dispenser – and with wet hands as we’ve seen before, you really need to be Fukimoto-san, high-tech solder expert.
There is however, a way out. To reverse Joe’s mantra and do it backwards: first FOLD, then SHAKE.
Fold, as in have the single sheets pre-folded in a dispenser you can extricate them from with wet hands. NONE of the existing ones on the market allow you to do this with any ease.
OK, so have a cup of coffee while you think about it – at Costa’s, where they seem to know a thing or two. Including – though they don’t know it – how to get your hands dry.
Because the paper napkin you take to your table is already pre-folded into four – and easily accessible, packed loose in an open-topped container along with the spoons, sugar, straws and stir-sticks for you to help yourself.
Picking up one of those without lifting a whole fistful is a breeze. So if your washroom had a box of those on the vanity slab beside each basin, it would be a doddle.
No more trudging to the dispenser or dryer, dripping on the floor. The FOLD is already done. You SHAKE your hands, keeping them in the basin so all the drops stay in the right place. Then you pick up a sheet and dry your hands. Clean, dry and safe, because all the germs go in the bin.
Back to Earth
So why all the rigmarole with expensive machines that don’t really work?
Though the legend is not lost on us that when the Americans sent the astronauts into space, they spent millions developing a pen that would write in a vacuum, upside down if necessary, and on all surfaces.
