Group,
We just had a Moose customer who was putting his 40 hours of fly-off
time on the airplane. The pressure relief valve took a dump and
relieved all of the air. (This is a unit supplied by Kimballs to
homebuiders and not Russian.)
He landed at a small strip. Rather than attempting to hand prop the
airplane, he asked if they had a bottle of compressed air. Yes, they
did! Out they come with a green bottle. Again, he is a bit reluctant
and asks if they are sure it is not oxygen. Again, they tell him it
is compressed air. He started the airplane and there was a bang. He
had the airplane started and may not have known what had happened at
that point. After returning to his home base it was discovered that
the starter hose blew apart, the filter blew through and the air
distributor stripped three of its studs out of the mating body plus a
host of internal damage.
Last month, I received a call from a ferry pilot. He had landed at an
airport and couldn't get the airplane started. The local FBO had
serviced the air system. He called to verify start procedures. When I
asked him what they had used, he said compressed air. I went further
and asked if he was sure it wasn't oxygen that they had used. No, it
was compressed air. I then asked what color the bottle was. Green. I
urged him to purge the air system of the oxygen before he did anything
else. Disaster avoided.
A Pitts Model 12 guy wasn't so lucky last summer when he was ferrying
his airplane and landed in Phoenix. He had similar results as the
Moose guy, but had to fix the airplane in 112 degree heat.
My question to the group is, will oxygen ever be in any other color
bottle, except green? I really don't think so, but I would like to
know conclusively.
Years ago, when I worked at Kay Larkin in Palatka, Florida there was a
line guy with little aviation experience who fueled a DC-3 with jet
fuel because it was a big airplane and according to his logic, all big
airplanes used jet fuel. This DC-3 was going to take a load of
skydivers up. The pilot noticed the jet fuel smell and queried the
line guy. The fuel was immediately drained. Another disaster avoided.
As PIC, we are responsible to make sure these things do not happen. To
me, the worst thing is to not know what we don't know. I am always
learning, preferably not the hard way!
I will post a short article with photos on oxygen and the air system on
our website next week.

Gill,
Answer: NO! Oxygen is always in a GREEN bottle (by US and international
standards). Commercially sold compressed air should never be in a GREEN
bottle. The yokes for the tanks are different to prevent some Darwinian
from crossing them up. Not to say that they do not afro engineer their way
around that safety system because they do. Nitrous Oxide is in a BLUE tank,
Nitrogen is in a YELLOW tank, and Compressed air is in a BLACK tank when
sold commercially.
So if you see some boozo coming toward your plane with a green or blue tank
in his hand tell him thanks but no thanks. O2 in a GREEN bottle is for
breathing not smoking! Tell the FBO operator that he needs to have the line
boy with the blue tank in his hand drug tested.

My local Co-op leases me compressed air in a yellow bottle clearly labeled
"Compressed Air" which is serviced by Airgas Company. There may not be a
"standard" color for compressed air.

Yellow is the international standard for compressed air tanks or sometimes
called "breathing air". My local welding shop's compressed air tanks have
always been yellow.

and nitrogen is black,
yes oxygen is green and nitrous is blue -
The other doc just mixed up compressed air and nitrogen
compressed air can be in any color (scuba tank) but when obtained
from a gas supplier it is yellow.

Black and yellow also (black overall tank with a yellow band around the
top).
Sorry, I forgot about the yellow band around the top when I wrote black.

One should never reply to anything after two Margaritas and Japanese
supper. Disreguard Yellow and Black. It should read green and black for
compressed air. That is what we get in our OR to drive our drills for Ortho
guys. Me, I prefer a Bard Parker but I do not have to cut or drill bones
either. Our H tanks of compressed air come in Black and Green.
Make it the 3 sorry...I'm done.
