Appreciate any assistance advise on the following: Can the following be stored together safely in a caged area inside a small warehouse? All are in small amounts and are used on aircraft UN1044 Compressed or liquefied gas UN1072 Oxygen compressed UN 0323 explosive 1.4S UN 3363 Dangerous Goods in Apparatus UN 2990 LIFE-SAVING APPLIANCE, SELF-INFLATING UN2795 BATTERIES,WET,FILLED WITH ALKALI Thanks mike

On the face of it this wouldn't comply with GN2 BCGA COP...that said small quantities can be stored inside as you will probably be more worried about theft of the small cylinders...the fire risk assessment and DSEAR assessment for the building would have to be updated accordingly...if MOD site then Defence fire would need to be involved..

I would suggest if these are in small amounts e.g. Limited Quantity then yes. UN 1044 is generally safe if they are protected against inadvertent discharge. Being regulated Dangerous Goods I assume they are packed in UN approved packaging. Further consideration perhaps to length of time stored, early warning in case of fire

Whether this is a spoof posting or not, UN1044 is compressed or liquified gas Good old Wikipedia says UN 1044 2 Fire extinguishers containing compressed or liquefied gas So looks like carbon dioxide fire exinguishers So just because the original post says UN1044, its is wrong of others to leap to the conclusion that LPG was being discussed. Dom't jump to conclusions All of the other items in the OP are found around aircraft. My only query would be the use of Co2 - the last time I checked Halon or BCF was still used for onboard aircraft fire extinguishers. Co2 was used for ground engineers fire fighting equipment.

Have to agree with Nici, there has been no mention of LPG. Interesting how this has been interpreted. If you think about it the Risk Assessment has been done for you, these are UN approved and as mentioned in small amounts, and are used on aircraft. These can all be transported in a passenger aircraft quite safely together albeit a few special provisions needs to be applied), storing them in a warehouse in a cage would be an extremely low risk.

As per my knowledge and thinking it should not be stored together. 1. Considering that UN 1044 2 Fire extinguishers containing compressed or liquefied gas, in case of release it may cause asphyxiation. 2. Oxygen release will aid fire and will cause more damage. 3. Explosives need to be stored as per the guide lines or rule book. In contact with oxygen it will be more dangerous. 4. Alkalies shall not be stored along with life saving eqipment as any spillage will lead to damage to equipment.
