Tom,

What is with you?  No where in these standards can I find a mandate to =
paint 3" MOD numbers on both sides of the tanks.  This system is so =
simple and so effective as to be almost self evident.  Everyone =
understands the perfectly clear and sensible rationale for doing this.  =
Why can't you simply place this requirement at or near the beginning of =
your list?

As for the student who unfortunately breathed the unmarked unanalyzed =
gas.  This gas was described as "air" and was his "bailout".   May I =
have the temerity to ask whose idea was it to bail out to "air". Was =
this the student's or Gurr's?  Under the stressful conditions which =
might precipitate the need to bailout it would seem to me to be the last =
gas one would want to switch over to in a crisis situation. We all =
remember what happened to Rob Parker when he switched over to air deep =
and I am sure that Abner Chowdry remembers what happens under these =
circumstances all too well.

Best regards,

Bill

    Bill
    What is with you. We do not allow as you accuse.=20
    some idiot filled a cylinder labeled as air with a hot mix and left =
the air label on it. The diver had been using the same air cylinder all =
week as a bailout cylinder and had no reason to think someone would fill =
it with a hot mix.
    =20
    If you dived a cylinder yesterday that had air in it and was labeled =
air and you left it at for instance at Brownies dive shop  would you =
suspect overnight someone had changed the mix?
    =20
    As per IANTD mixing standards=20
    LABELING BOTTOM MIX EANx MIXTURES WITH LESS THAN 41% OXYGEN


        a.. Where applicable cylinders must be marked per legal =
requirements in addition to the below=20


        b.. Cylinders painted yellow must be labeled with a 4 inches (10 =
centimeters) green band. The band must wrap around the tank starting at =
the flat of the cylinder. The label must state "Enriched Air Nitrox" (or =
an applicable acronym). IANTD has EANx decals available for labeling =
tanks.=20


        c.. Cylinders painted with colors other than yellow require a 6 =
inches (15 centimeter) Enriched Air Nitrox band (decal) with the top 1 =
inch (2.5 centimeters) and the bottom 1 inch (2.5 centimeters) yellow. =
The middle of the band (decal) should be printed with a green background =
and the message, "Enriched Air Nitrox" (or an applicable acronym) =
printed in yellow for easy identification.=20


        d.. Nitrox (EANx) cylinders must have Cylinder Contents Labels =
affixed to them. The Contents label must state the oxygen percentage =
currently in the cylinder and the Maximum Operating Depth (MOD). The =
label must be dated and signed by the person who purchased (or =
requested) the mix (verifying he/she confirmed the O2 percentage).=20


        1.. This label may be a separate label, or part of the EANx =
band. IANTD has waterproof, reusable Cylinder Contents labels and =
cylinder content tape available for order.=20


        1.. Nitrox (EANx) cylinders must have a current Visual =
Inspection (VIP) decal stated that oxygen-compatible lubricants have =
been used in the system (valve, tank neck, and/or cylinder). EANx =
cylinders used with EAN 41, or greater, or for direct partial pressure =
blending use, must have an Oxygen Service Rated VIP decal. IANTD has VIP =
decals (which also cover both tank and valve inspections) available for =
order.=20

        a.. It is recommended that an additional label using one of the =
following options be used, these do not replace the requirement for the =
wrap around labels
    I A Decal stating MOD to be placed length wise on the cylinder (IAND =
inc./IANTD has these with both a fixed=20

    MOD plus blank ones for the user to fill in the MOD, these are blue =
with white lettering=20

    II The MOD may also be painted on the cylinder

    III A cylinder wrap suitable for regulator hose storage with the MOD =
boldly marked on it may also be used=20

    (these are also available through IAND inc. / IANTD


   =20

    D. LABELING EANx AND DECOMPRESSION CYLINDERS (GREATER THAN 40%) AND =
OXYGEN (OR MIXTURES GREATER THAN 85% OXYGEN) MIXTURES


        a.. Cylinders containing EAN 40 to 84 must have either a =
color-coded green and white label decal boldly stating, "Decompression =
Mix EAN* _____." or they may use the "Breathing Gases Other Than Air" =
decal that is red and white. (Note! This decal may be used with any gas =
mixture as long as the mix and MOD are filled in) This label must be 10 =
inches (25 centimeters) long and 4 inches (10 centimeters) wide. IANTD =
has Cylinder Contents labels available for order. * Or, equivalent =
acronym. These labels must be wrapped around the cylinder at the flat of =
the cylinder=20


        b.. The decompression cylinder with the highest EANx mixture or =
oxygen must have some form of protective mechanism to prevent the diver =
from accidentally breathing from it. This may be a cover, bungie wrap or =
other suitable means. IAND inc. / IANTD has a protective device =
available=20


        c.. All decompression cylinders must have a tape or label above =
the flat of the cylinder visible to the user with the mix or MOD or both =
marked. IAND inc. IANTD has these with pre marked mix and MOD as well as =
ones with blank spaces for the user to fill in.=20


        d.. Cylinders containing oxygen levels of 85% or greater must =
adhere to one of the following:=20


        1.. Be painted either green or white with the word oxygen and =
MOD 20 fsw (6 msw) legible=20


        2.. Have a 10 inches (25 centimeters) long by 4 inches (10 =
centimeters) wide green adhesive band decal with the word "OXYGEN" and =
MOD clearly and prominently printed in white on it. IANTD has waterproof =
Oxygen Cylinder Decals available for order.=20

        a.. It is recommended that an additional label using one of the =
following options, these do not replace the requirement for the wrap =
around labels
    I A Decal stating MOD to be placed length wise on the cylinder (IAND =
inc./IANTD has these with both a fixed=20

    MOD plus blank ones for the user to fill in the MOD, these are blue =
with white lettering=20

    II The MOD may also be painted on the cylinder

    III A cylinder wrap suitable for regulator hose storage with the MOD =
boldly marked on it may also be used=20

    (these are also available through IAND inc. / IANTD


   =20

        a.. LABELING TRIMIX MIXTURES

        a.. Cylinders containing Trimix must be labeled with the word, =
"Trimix", or "Breathing gas other than air". A Cylinder Contents Label =
or tape reflecting the percentages of Oxygen, and Helium must be affixed =
to the tank.=20
