Identification of an unlabeled lecture bottle 4

[Ashborer]

I found an unlabeled lecture bottle in a biology storage room. I would like some help identifying the chemical if possible, so that I can enter it properly into our waste stream. The lecture bottle is approximately 12" in length, and contains the following information:

Bottle colors: top 20% is green, bottom 80% is grey.
Valve markings: the Ohio chem & mfg. co, Cleveland, Ohio
bottle markings:1042, 1CC-3A-2C15, A-8098, 00-MCO, 0-36 P98
defaced bottle marking: diamond with green interior and light yellow exterior

I'm also including a picture in case this helps- thanks in advance for any help you can offer!

Looks like a high pressure gas bottle.

Ash borer,

1CC-3A-2C15 Recheck that marking to see if it says 1CC-3A-2015 .
That appears to be the pressure rating for the re fill of that bottle.
The color of the bottle entirely depends on the gas supplier you need to see if a company label or supplier name is stamped someher somewhere.
Other than that for the most part Green is a color assigned to oxidizers. and grey or silver is assigned to gasses that are physically dangerous.

Thanks for your help Berkshire. Unfortunately the manufacturer label is long gone, which is why I was hoping someone might have seen this lecture bottle type and color code before and had it trigger a memory. It's definitely a high pressure bottle; I'm thinking it may be CO2 or O2 since it was found in a bio dept. Because of the color codes, I can't confirm that, but it may be something along those lines.

Ashborer,
The bottle looks like a 2x12 medical oxygen bottle with that pillar valve, however if it was just oxygen the bottle should just be the green color of the top. See if you can find the compressed gas supplier for your institution and take it over to them for an opinion.

What direction are the threads - An O2 bottle or HP gas bottle like N2 or CO2 will have different threads than an acetylene or fuel bottle.

Obviously you can vent oxygen to air (away from flames), N2 or CO2 are safe also. A burnable gas (ether ?) or refrigerant or a medical device calibration gas is different.

I'd suspect oxygen in something that small. Get it out of the lecture room in any case, get it stored with the top vertical out of doors, secured so it can't get tipped over, run over, or dropped over and break the valve.

The cylinder has an A pillar valve like a medical oxy bottle it looks suspiciously like a CGA870_3A fitting.
I am at the limits of my knowlege to know what else that type of valve is used for.

Call Hazmat and get rid of it??

Dear Racookpe1978- the thread is very difficult to view because of the type of valve, but it appears to be a left handed/ clockwise threading.
Dear B.E.- Thank you very much, your input has been very helpful

Cylinder color should never be used for positive identification. You should contact your gas supplier for help in determining the contents.

It seems that you have incorrectly transcribed the numbers. "1CC-3A-2C15" is probably ICC-3A-2015

It is a pin indexed yoke valve. If you could turn the bottle 90 degrees towards the top of the photo it would show then pin lay out. This would give some idea of what may have been in it. This type of connector usually is a medical bottle, however with many of these older type bottles what was originally in them is not what is in them now. You can contact a waste company to dispose of it, most likely as an unknown gas.
