3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
gas for medical use
any gas or mixture of gases intended to be administered to patients for therapeutic, diagnostic or prophylactic purposes, with or without pharmacological action, or to be used for surgical tools, and It covers both medicinal and medical gases (see ISO 5145)
3.2
Inert gas
non-toxic, non-corrosive, non-flammable and non-oxidizing gas or gas mixture
3.3
synthetic air
for medical use to refer to pharmacopoeia. monograph 1684, and for other use mixtures containing 20 % to
23,5 % oxygen in nitrogen to be considered
3.4
industrial gas
gas or gas mixtures not covered by 3.1 and not used for breathing gas use
3.5
breathing gas
gas filled in cylinders for breathing and diving application, excluding gas for medical use.
5 Principle
Colour coding is used to give information about the contents of gas cylinders from a distance e.g. in case of emergency and to distinguish between cylinders used for industrial and medical uses.
For all applications, hazard/identification colours shall be applied to cylinder shoulders.
For gases for medical use, the body of the cylinder shall also be colour coded (see 6.3).
For applications other than medical, the cylinder body may be coloured. The use of a colour for the cylinder body that allows misinterpretation of the hazard of the gas is not allowed
Colours used shall be in accordance with RAL register 840HR given in Annex A or equivalent.
6 Colour coding system
6.1 General
The following colour coding requirements are applicable to the shoulder and the body of the cylinder.
6.2 Shoulder
6.2.1 General
Gas cylinders are assigned colours using three methods. Colours are chosen based on the properties of the contents in accordance with the hazard of the gas filled in the cylinder (6.2.2). Some specific gases and gas mixtures are assigned colours relevant to that gas or gas mixture as noted in 6.2.3 and 6.2.6. Instead of the hazard colour, other colour(s) may be assigned based on the components of a gas mixture (6.2.3 or 6.2.4 or
6.2.5).
Annex D gives guidance for the selection of shoulder colours.
6.2.2 Gas properties
6.2.2.1 Unless specifically identified in 6.2.3. 6.2.4, 6.2.5 or 6.2.6, all gases and gas mixtures shall be identified by a colour coding indicating the properties of the contents in accordance with the colour of the danger labels as specified in RID/ADR.
When two colours are applied to the cylinder shoulder, they should be in one of the formats (bands or quadrants) Identified In Annex B.
6.2.2.2 For gases with a single danger:
a) toxic and/or corrosive (in accordance with ISO 10298 and ISO 13338)— yellow;
b) flammable (in accordance with EN ISO 10156)— red;
c) oxidizing (in accordance with EN ISO 10156)— light blue:
d) inert1) — bright green.
The colour BRIGHT GREEN shall not be used for air for medical use or breathing application (see 6.2.5).
6.2.2.3 For gases with more than one danger:
When a gas o mixture has two hazard properties, then the cylinder shoulder shall be coloured in accordance with the pi-imary hazard. The colour of the secondary hazard (flammable or oxidizing) may also be applied to the cylinder shoulder:
a) toxic (and/or corrosive) and flammable — yellow plus red:
b) toxic (and/or corrosive) and oxidizing — yellow plus light blue.
6.2.3 Specific single gases
6.2.3.1 The following gases shall be identified by specific colours rather than the colour system defined in
6.2.2.
a) Flammable gases:
Acetylene — Maroon.
b) Oxidizing gases:
Oxygen — White;
Nitrous oxide — Blue.
6.2.3.2 Inert gases for medical application shall be further differentiated by use of the following colours:
a) Argon — Dark green:
b) Nitrogen — Black:BS EN 1089-3-2011 pdf download.
