HSE Guidance for cleaning of fuel tank ???

Post by lewes » Mon May 17, 2010 11:51 am

Is there a HSG document or strict guidance for the cleaning of fuel tanks ???

I have been asked the question and I don't think there is but its Monday morning so cant confirm !!! :D

These are fuel tanks that go on vehicles and not Tankers or bulk storage of fuel.

Thanks for any input

What are you trying to clean from it??
You need to think about containment of any liquid and disposal of the waste.
A COSHH assessment should be carried out too.

I'm sure someone will be able to add more soon...

At the moment the vehicle tanks are drained to suitable containers and a soapy solution is used and rinsed several times.

These vehicle tanks are normally used for diesel

Diesel isnt flammable so you dont have to worry about that.
But why clean them??
If you leave any water in the tanks before re-use this may end up being worse than any contamination you might have.
If you're trying to clean red diesel staining, you wont!!

I understand that vast quantities of Diesel fumes in an enclosed environment can be flammable.

The tanks are removed from the vehicle as there can be a build up of sludge in the bottom of the tank.

Weve had an incident and im looking into it further

Flash point of diesel is around 62C. If it gets especially hot you might have a flammability problem, but at 62C your guys working will already have given up!!
Auto-ignition temp of diesel is 210C, so I wouldnt worry about that!!

The correct quantities of diesel vapour and oxygen at high presures can be explosive, but you'd have to inside a diesel engine to experience it.
