How could you use a scuba air tank and breathing thing in a house or apartment block fire situation?
Fireman gear is not very different from a scuba tank; in fact it works the same way. The main difference is that a scuba tank has to weigh enough to compensate the bouyancy of the air inside so you don't float to the top when wearing it, while a fireman's breathing equipment is made to be lightweight so the fireman isn't weighed down as much by it.
Why can't scuba divers just use a really long air hose above the water to breathe, instead of air tanks that need refilling?
From MuadDib: The origional dive suits did have hoses.There are divers that still breath off of surface supply, but normally it's in a commercial setting in relatively shallow water. There is an air compressor on the boat for that. I have a friend who's a commercial diver, he said it's kind of restrictive and you have to be careful of the hose all the time. I SCUBA dive, and there are time where a hose isn't as practical. Cave or wreck diving would be problematic for this. Also if you have multiple divers on the same trip, like ran from a scuba shop, then the hoses would get tangled.
A scuba tank is technically just canned air.
Jumbo: The contents of a scuba tank are just air. It isn’t any more special other than not having pollutants from cars n shit. Common misconception is that it’s oxygen. It is just compressed air.
PMRump: Sometimes it's nitrox, which is just nitrogen and oxygen, much like the main components of our atmosphere. And for deep tech dives, can even include helium. But for most shallow and mid level dives, yup, just "canned air".
SMACO Mini scuba tank is really good as my primary or spare equipment.
Floyd A: The worst part of diving is how cost prohibitive it is to get started. But SMACO solved my problem very well, My first setup was SMACO S400 and it gave me the opportunity to enjoy the hobby while investing in better and larger capacity equipment as I progressed.
