For those of us who've done a bit of SCUBA diving (not for me any longer, with a recurring pneumothorax), you'll know there are few things worse than air that tastes of oil and diesel fumes.
What is proposed here is simple. Refill tanks in a room filled with flowers, or baking bread, or fresh coffee.
That
way you can be transported away during your dive... I remember the fresh croissants from the boulangerie on Avenue du Winston Churchill, in Porte du Charenton... the waiter with the outrageous accent, in Piazza san Marco... my brother was running away from the bull, bits of new-mown hay stuck to him everywhere, laughing fit to burst...

Reminiscing while wandering deep into an underwater cave. |
|
| |
And offering your reg to the fish, as you become progressively more "narced", yeah... I thought about that. |
|
| |
Doesn't the air need to be completely dry? I think that would remove a good deal of the scents. |
|
| |
Yeah, completely is such a misused word. :) |
|
| |
Low humidity is good. If it is too dry, then it really dries out your throat. Humidity is only a problem if you open the tank valve for too long without a (secondary) regulator attached. The rapid drop in pressure causes moisture to condense in the tank, which will rust it from the inside out. |
|
| |
Why would you open the valve without the regulator attached? To CHECK THE AIR FOR EXHAUST FUMES! <ahem> If you smell oil, diesel, et cetera, do not use the air. |
|
| |
So, some humidity is OK, but I’m not sure how this scented air will ‘taste’. The nose isn’t used much while diving. Can we taste these fragrances? |
|
| |
Good point. Most tastes are based around the olfactory senses, too. |
|
| |
Try this: Pinch your nose closed and sprinkle some powdered cinnamon on your tongue. Try to taste it. Then let go of your nose. It's an amazing trick. |
|

you're kidding, right!!! i LOVE the air you get in scuba tanks!!!! if only i had my own tank (...and regulator....and compressor), i'd carry it around with me all day!! perhaps one of those little ones they have on bay watch would be more convenient |
|

There are a lot of filters that the air goes through so whilst you would have some sense of a different smell it probably wouldnt smell how you wanted it to. Plus if you (like me) fill your tanks and then dont dive for a couple of months it might get a bit funky. |
|
| |
I have thought it would be a good idea to have a filter put between the tank and the compressor that would have certain smells in (such as mint, chocolate, fruit) as these are organic compounds which are not difficult to make, non-corrosive, safe to breathe (in small quantities) and strong enough to taste even if you are only breathing through your nose a tiny amount. |
|
| |
The problem is, if you do get a bad, diesel-y fill you probably want to be able to taste it before you go diving. |
|
| |
I'm with Shz and miasere. The air
should
be clean and dry in the tanks. Diesel
smelling air is bad and can poison you. |
|
| |
You could (as miasere says) add smells
downsream from the tank (say at the
second stage regulator). Not sure
whether you 'd smell them or whether
they'd just set off alergies in those
susceptible. If you're going to
do that, you might also be able to add
moisture there so that your throat is not
so dry after a long dive. |
|
| |
Erhm, the tanks are pressurized. Standard air pressure would last about one or two breaths. |
|
| |
Yeah, we all know that. Why would you think...? |
