The labels for Avgas grades are printed in white letters and numbers on a red background. Red is used for the background because it is an indication of the special care which must be taken in the handling of the more volatile fuels. White lettering is used for contrast. The label may take the form of a stencil and painted on or as a decal with the applicable colour-coding. Labels and bands shall, as a minimum, he placed at the inlets and outlets of each Avgas fuel storage facility above ground storage tank. The labelling system shall always have adjacent to it a band of the correct colour representing the grade of fuel of the labelling.
Each grade of Avgas is dyed a distinctive colour:
Grade 80 is red, Grade 82 UI.. is purple, Grade 91 is brown, Grade 100 is green, and Grade 1 OOLL is blue, This colour code shall mark all major valves and pumps with the same colour as the Avgas within the particular system.
Pipelines, minor valves (e.g. pressure relief, air elimination), filter vessels (and associated drain valves) shall be either painted the same identifying colour or painted white or aluminium. Large pipelines (greater than 75 mm (3 in.)) shall be marked with a label/band combination or band. Small pipelines (75 mm (3 in.) or less) shall be marked with a band of the proper colour at intervals as described in 6.2.
Figure 1 illustrates the labelling and colour coding for Avgas. The large colour designation on the right of the gasoline grade markings represents the colour for the colour code.
The labels for jet fuel grades are printed in white letters and numbers on a black background. Black is used because it offers a distinct difference from the red used for Avgas grades. Again, white is used for contrast. The label may take the form of a stencil and painted on, or as a decal with the applicable colour-coding. Labels shall, as a minimum, be placed at the inlets and outlets of each Avgas fuel storage facility above ground storage tank.
The labelling system shall always have adjacent to it a band of the correct colour representing the grade of fuel of the labelling.
None of the jet fuels is dyed; the three grades normally vary naturally from white to light yellow. Thus the colours used for handing have no relation to the colour of the jet fuel. They are as follows: Jet A is black. Jet A-i is black, and Jet B is yellow. The more volatile product, Jet B, is distinguished by colour for the banding programme. This colour code shall mark all major valves and hydrant pit covers with the same colour as the aviation fuel within the particular system.
