ldentification is achieved by symbols and text representing the contents of the cylinderbeing either directly printed or stencilled on the cylinder’s surface or in the form ofpre-printed labels applied to the cylinder’s surface.
The cylinder shall be legibly labelled.
NOTE:ADG Code, Labelling of Workplace Hazardous Chemicals CoP, SUSMP and TGO No.69have labelling requirements that may apply to gas cylinders.
As the colour coding of a cylinder includes the body colour and if applicable，its bodylabels,not more than 20%of the body of the cylinder may be used for promotional ormarketing purposes.
4.2 Location and durability4.2.1 Location of label(s)
The required label(s) should be located as close as practicable to the valve end of each gascylinder or to the outlet on a bundle of cylinders.
On a composite cylinder a complying label may be applied under a clear outer resin layer orunder a clear outer filament winding.
4.2.2 Durability of labels
Each label and their means of attachment shall be of material that ensures the label willremain in place and be legible after normal exposure to conditions incident to transport,storage and use.
4.3 Body labels
Body labels may be used on the body of a cylinder to identify the name and/or the chemicalsymbol of the contained gas.
When used，body labels shall be applied to two opposing sides of a cylinder，unless thewater capacity of the cylinder is less than 15 L where a single body label may be applied.For bundles of cylinders a body label shall be applied to a minimum of one cylinder on atleast two opposite sides of the bundle.
The body label text shall be in either black or white,with the colour being selected tocontrast with the body colour.
Body labels shall be clearly visible.4.4Special labelling
Where the contents of the cylinder have a special condition，such as a specific storagetemperature，or the constituents are in special or laboratory proportions，such asmulti-component gas mixtures，the cylinder shall be identified in accordance with one ofthe following:
(a) By labelling to show the special condition, and the special or analysed proportions.(b)By a label indicating that the contents are a special gas mixture and referring to a
report that is attached to the cylinder.
The major constituent or balance gas need not have the percentage marked and should beshown as,‘IN _(name of balance gas)’ or ‘BALANCE_
(name of balance gas)’. The minor constituents should have their proportions given as apercentage, or p.p.m. (volume) or other means as appropriate.
5 COLOUR CODING
5.1 General
The name and specification of the colours adopted by this Standard refer to those specified in the current edition of AS 2700.
The general basis of the colour code is to identify the characteristics of the gas.
Toxic ……………………………………………………………………………………………. Golden Yellow.
Flammable ………………………………………………………………………………………….. Signal Red.
Oxidizing ……………………………………………………………………………………………….. Bluebell.
Non-flammable, non-toxic …………………………………………………………………… Apple Green.
The cylinder colours to be used to identify the gas contents of all gas cylinders shall be in ccordance with Table 1 except for the following:
(a) Medical gas cylinders shall be in accordance with Table 2.
(b) Non-medical breathing gas cylinders shall have shoulder colours in accordance with Table 2 with a Green Grey body colour.
(c) Refrigerant gas cylinders, if coloured, shall have regions permanently coloured in accordance with Table 3.
Painting and other permanent coatings or treatments including weather resistant plastic films are acceptable methods of colouring.
5.2 Requirements for coatings The paint permanent coating or film used shall be fade and ultraviolet-resistant as far as practicable. For composite gas cylinders, a clear or translucent film may be specified by the cylinder manufacturer to assist inspection of the fibre condition. Where a coloured coating or film is applied to a composite gas cylinder, the colour shall be as specified in this Standard. A white opaque plastic film is an acceptable alternative for the colour white.
5.3 Eductor tubes A cylinder with a single outlet valve fitted with an eductor tube for liquid withdrawal, shall be labelled to identify the liquid withdrawal facility with the clearly written word(s) ‘Liquid; or ‘Liquid Withdrawal’.
