One of the depots of the company I work for has a growing business in the supply of LPG to both the local community and local businesses.  The issue they have is that the demand is rapidly outgrowing the outside cage they have for storing both full and returned cylinders.  They are currently storing around 1000kgs of LPG and around 50 empty cylinders in and around an outside cage.  The depot manager has thoughts of using a shipping container to store the full cylinders and use the existing cage to store the empties.  The issue for me is that the shipping container is in a line of five with numbers 1 and 2 used as tool storage, he is proposing number three to store LPG, numbers 4 and 5 hold red and white diesel tanks.  I have lost touch a bit with the regulations around storage of LPG.  I am visiting the depot tomorrow and I am minded to say no and get further external storage but would welcome any advice on the issue.

Ventilation The preferred location for the storage of drummed flammable liquids and compressed / liquefied gases is in the open air, to allow vapours to be dispersed effectively. When located in buildings, the operator should demonstrate that there is an adequate level of ventilation achieved by either the presence of a sufficient size and number of permanent openings such as louvres or mechanical ventilation. If stored indoors, flammable gases such as LPG may only be stored in purpose built compartments or buildings constructed with fire resistant walls and explosion relief.

If you do an internet search on BCGA CP44  and GN2 it will give you guidance for the storage of gas.
