A vent system has a vent stack 2 for venting a tank fluid (e.g., kerosine vapour) from a fuel tank 3 external to the vent stack 2. The vent stack 2 has a conduit 21 with an inlet 21a and outlet 21b. The outlet 21b opens to atmosphere 6. An opening 23 into the conduit 21 between the inlet 21a and outlet 21b enables, in use, tank fluid to flow from the fuel tank 3 via the opening 23 to the outlet 21b. The vent stack 2 has a fluid mover 25 (e.g., fan) to cause a mixer fluid (e.g., air) to flow from the inlet 21a through the conduit 21 to the outlet 21b, thereby to mix the mixer fluid with the tank fluid in the conduit 21, upstream of the outlet 21b. Fuel gases may be diluted below their lower flammability limit. Inert gas 60 may be provided.
