What should I do with avgas left in a tank being decommissioned?

With avgas left in a tank being decommissioned, book fuel removal ahead of the tank contractor, tell us the tank size, what is in it and the dip reading, and keep the fill and vent points accessible. Call 07950 582635 or send an enquiry.

Storing avgas in a tank being decommissioned

Leave the fuel in the tank until collection; the tank must not be cut or opened until it has been emptied and made gas-free.

Avgas is highly flammable with a flash point far below normal temperatures, harmful if swallowed and it enters the airways, and toxic to aquatic life. The lead compound in 100LL is toxic and may damage fertility.
