Use a second source when your plant goes up in flames, you are covered (been there from the client side several times). Go out of the medical side, and you no longer need to worry about some issues. The SDS’s may differ due to the differing requirements in spec. Gotta be dewpoint below -65C (-85F)) to prevent icing in the lines and regulators. The masks for passengers use a chemical generator) has additional requirements for moisture (dry. Aviation O2 (think military pilots, flight deck supplies for commercial, unpressurized cabins, etc. O2 from concentrators is a different beast, and may be much lower purity.

USP (medical) O2 bottles are required to undergo vacuum purge prior to filling, though the required purity is only 99.5%, as long as the non-O2 components are non-hazardous (I don’t have the full standard on hand, but I would presume N2, Argon, and other inerts are non-issues. THe bottles are as clean as they can be, as any contamination in the essentially pure O2 at pressure can lead to unpleasantness, but the bottles are not purged unless there is a reason, so there may be minor impurities that have no effect in industrial usage, but could be harmful in medical use. The difference between the various O2 types is in the bottle design and the fill method, to meet the appropriate requirements (this is for air-liquid process, where the fill is by evaporating near-pure liquid O2.) For welding and cutting, the O2 needs to be well above 99.5%, but need not be the 99.999% research grade. The sideline into O2 gave a bunch of people a chance to be ignorant.
#Tank force hacks how to
A reasonable question is: How to insure that, given the size of the bottle, there can not be a sufficient buildup to be a problem in the event of a leak.Ĭhris and macona: The lack of clue in this subthread is truly special. See: It is one of the many gasses I need to be concerned with professionally, and I have no reason to disagree with Dr Clarke, nor should you. You may never feel the buildup, and by the time 10% hits, you are in the damage zone. At about 5%, you start to get pretty foggy.
THere are a couple knowledgeable in this comment set, but a lot of WTF?įirst subthread started by Clarke: Why are people arguing here? Taking a full lungful from the tank (dry, cold, etc) is not the same as the diminishing O2 over time from a leak. Posted in Misc Hacks Tagged co2, ESP8266, sodastream Post navigationĭropping this at the end because all I can say is so much wrong here. Overall, it’s a great project and one that recalls us of continuous-ink printer hacks. Plus, there’s no need to regularly buy new bottles! It’s likely that the Sodastream prices could still be beat even if a food-safe CO2 source was used. The project brings costs down to 18 cents per liter of seltzer, versus 38 cents for the Sodastream gas supply. notes that at her rate of drinking one bottle a day, the tank should last her a full 7 years or so.
The tank is also placed on a custom scale built with load cells and an ESP8266, which allows monitoring of how much gas is left. However, safety was given due attention in that a CO2 monitor was installed to make aware of any dangerous leaks. Using welding-grade gas in your drinking water is probably a really bad idea, but was willing to take the nisk. This is easy enough, and just uses a off the shelf adapter. The simple part of the hack is using an adapter to connect the Sodastream apparatus to a 50 lb CO2 tank from the welding store.
#Tank force hacks upgrade
decided to upgrade her machine to avoid this problem, and added some smarts while she was at it. However, replenishing the tiny gas canisters is expensive and wasteful. Sodastream machines are popular amongst people who like to make their own seltzer water at home.
