I need help finding guidance about how close to a building we can site a 45000ltr Diesel Storage Tank.

I have looked a DSEAR Regs but cannot find anything definitive about Diesel other than it may be considered a low risk due to low flash point. I have looked at HSG176 which does give guidance on separation of "Tanks" from buildings but again does not give definitive details on Diesel.

Does anyone here have any suggestions please.

Thanks in Advance

Suggest looking at the crisis response pages: http://www.crisis-response.com/forum/index.php?topic=6679.0;wap2 

Its a quite useful area with some in-depth references to HSE and other related materials.

Hi Mark,

I'm not an expect in this field but we had diesel tanks of a similar size in my old workplace. These were located internally (transport garage) due to the flash point is quite high. We had double skinned tanks (alarmed) and concrete bunding around the tanks.

Again, I'm not 100% confident but might be worth checking COMAH regs as you have 2% and aggrigation rules etc. I'm not sure what other products you may or may not be storing? I guess the key would be risk assessment, emergency procedures etc etc.

Hope it helps!

Diesel is now classed as a dangerous substances as detailed in DSEAR as you have identified. As well as identifying the required separation distance from a building you will have to complete a hazardous area assessment (DSEAR Reg 7). You will also need to identify all potential sources of ignition for your hazardous area assessment and any potential grades of release on which to base you conclusions.

Diesel never used to be considered a DSEAR issue, but the classification was changed about 2yrs ago under the CLP regs/guidance.

As a technical note - diesel is not too dangerous because it has a HIGH flash point NOT a LOW flashpoint - see original comment by poster!!

I work in oil/gas/petrochem so DSEAR is a regular topic.

COMAH Tier 1 requires 200 tonnes on site. COMAH Tier 250 tonnes.

Diesel is a Cat 3 flammable liquid 

Happy to help, if required

Just to confirm 45,000 L not 4,500 L ?

But assuming it is 45,000 would the suppliers be of assistance in locating appropriate documents regarding installation.

Thanks Ian Bell2,

Your quite right high flashpoint of +60c or thereabouts. Thank you for your input, one of the sites I cover is Lower Tier COMAH, we store Flammable Aerosols on pallets in a warehouse, I am familiar with those regs and aggragation rules, thankfully this tank will be sited at our other depot where this is not a factor.

As somone else pointed out 45,000 ltrs or 45 - 50 tons of diesel will not be a COMAH issue.

I think I will defer to the guidance in HSG176 and go for at least 8m from a building after taking in all the other considerations such as environmental impact.

Regards

Mark

Possibly talking of smaller tanks but may be of interest

You need to look at the Oil Storage (England) Regulations as diesel falls under the definition of oils in these regs.  There is a govt website that gives a summary of all the relevant things you need to know.  I would post the link here but my pc has decided to wipe all my bookmarks today so I am struggling with the internet a bit at the moment.  DSEAR guidance isn't very helpful where diesel installations are concerned.

We have just had a new self bunded integrated 50,000L tank installed - we were advised 10m from the nearest building just in case it helps total cost of installation was around £50,000 inc VAT and removal of the old tanks.

Further to the earlier comments and observations the Oil Storage (England) Regulations is a good sourse document. I appreciate you may be using a double skinned tank but also consider drains under ground voids (cable runs) etc and other water courses when siting the tank. You will also need to consider drip trays for nozzles etc, a maintenance and inspection regime, spillage equipment and suitable training.

I believe I used document PPG2 when I did mine many moons ago.

Hope this helps.
