# What should I do with unidentified fuel left after a site closure?

In brief

With unidentified fuel left after a site closure, list every tank and container with approximate volumes, tell us the deadline, and make sure there will still be access on collection day. Call [07950 582635](tel:+447950582635) or [send an enquiry](https://cityfuel.services/enquiry/).

## Storing unidentified fuel left after a site closure

Keep the fuel in its tanks or sealed containers, locked and bunded, until collection.

## Hazards to keep in mind with unidentified fuel

Assume it is flammable and harmful until proven otherwise: keep it closed, away from ignition sources and out of drains.

## How City Fuel Services handles unidentified fuel

Send us the five details: business and postcode, roughly how much unidentified fuel there is, what it is and any contamination, how it is stored and reached, and whether you need one collection or regular ones. We assess it, confirm a rebate or a collection charge, and collect on a consignment note.

## Terms used in this answer

**Bund**: A wall, tray or outer case around a fuel container that holds any leak. For oil and fuel stored at a business, bunds for tanks, bowsers and IBCs are sized at 110% of the container.
**DSEAR**: The Dangerous Substances and Explosive Atmospheres Regulations 2002. They require employers to assess and control fire and explosion risks from substances such as petrol.
