Hi,

We have a problem where gas cylinders (not all identifiable!) are dumped in the grounds of our property or left behind when tentants leave and need to dispose of them.

At present they are collected and bought back and stored at the main depot until disposal arrangements are made.

I want to look at putting together a short procedure in how to deal with this and have found plenty of information on the storage etc of LPG's; but what happens when the cylinders are other gases or not even identifiable? The obvious safety issues concern me with this! Also, the disposal company we have been using won't take them.

Also, am I correct in saying the manufacturer of the cylinder has a duty to take it back? (if we can identify the cylinder)

I have looked on the lpga's website and got a list of brand name's and suppliers of gas, but this is for lpg. Do I just phone the company up?

What if there is no obvious way of identifying the cyldiner? Where do we go from here?

Thanks for any guidance offered.

I should also add that I assume it's not correct to take them to LA amenity sites?

Also, if we are required to store them in the mean time can anyone point me in the direction of cage suppliers and guidance on what cylinders can/can't be stored together?

Cheers

Always a tricky one - LPG is usually straightforward as the scheme for collection does usually work well. For other gases i would talk to both British Oxygen and Air Products as they probably hold a signifiant section of the market even where other brand names are stated on the bottle. They will usually be very helpful. The return of bottles is usually of benefit to them.

As for storage the only real issue is if you have oxygen bottles among the "rescued items". These have to be stored at least 6m from flammable gases or have a firewall between.

Brenda,
have you tried the British Compressed Gas Association (BCGA)?
They have Guidance Notes on all aspects of cylinder use and storage.
If they can't help I'm at a loss to suggest anyone else.

Regards
John

Are all of the cylinders the squat shape used for LPG or are some the tall, thin, very heavy cylinders used for nitrogen, argon, etc? For the latter type of cylinder, the colour will indicate the contents; you should find the colour scheme on a supplier's website.

Hi Bob, haven’t e-mailed anyone in particular at this point no, although had a brief look on BOC’s website.

John, the guidance note’s you are talking about are the one’s you pay for are they?

Paul, the smaller one’s are fairly easy to identify and seem to be LPG’s. Have just found a guidance document explaining about the taller one’s and have identified it is a CO2 cylinder.

If I find details of the producer (not sure if that’s the correct term) on the cylinder, are they obliged to take it back?

Also, happy to keep oxygen and flammable cylinder’s separate, but is there a list of oxygen cylinders, are they a particular type or easily identifiable?

Cheers

The BGCGA site provides guidance on cylinder colours - unfortunately it is the new colour code system only. Oxygen used to be black with a white collar but i suugest you talk to the suppliers as they have the best knowledge bank

BCGA publication can be found under their publications heading/drop down menu and it is called TIS 6. You could also have a look at BOC publication - Safe Under Pressure which also includes a section on markings. Hope this helps

Great cheers, i'll have a look.

I'm still interested to know whether the producers of cylinders are obliged to take them back?

Bob,

I have to disagree with your advice regarding separation distances of gas bottles.

BCGA guidance note 2, the storage of gas cylinders in the workplace, gives minimum separation distances between oxygen and flammable gases as ZERO metres. The minimum distance between oxygen and LPG or other liquified flammables is quoted as 3 metres.

No sure where your 6 metres comes from?
