Safety Precautions; Specifications - Aston Martin V8 Vantage Workshop Manual

Normal Fuel Fill - Air displaced from the fuel tank during
filling can only exit via the fuel level vent valve and roll over
valves and be forced through the carbon canister. Any fuel
vapour in the displaced air is absorbed in the carbon filter
material. No fuel vapour can escape to the atmosphere.
Clean air then exits the carbon canister, via and additional
filter, to atmosphere.
Excessive Fuel Fill - In the event of overfilling of the fuel
tank, the fuel level vent valve will close at normal maximum
fuel level. Finally the roll over vent valve will close,
completely sealing the tank. Any excess pressure in the fuel
tank will 'blow off' via the Over-pressure vent valve (part of
the roll over vent valves) in the Fuel Level vent valve
assembly.

Safety Precautions

Operations on fuel system result in fuel liquid and vapour
being present in the working environment. This presents a
very serious risk and the following precautions must be
strictly observed:
Operations on refuelling and the fuel system must only
be performed by personnel who have completed
training on fuel handling.
Smoking must not be allowed near the working area.
"NO SMOKING" signs must be posted around the
working area.
Any operation which could involve sparks or naked
lights (e.g. battery testing, welding, metal grinding,
etc.) must not be allowed near the working area.
A CO2 fire extinguisher must be available close at
