I don't mean to be blunt but by your own admission you know next to nothing about this area and therefore you aren't a competent person to undertake this work.  The obvious high risk thing for me at a petrol station is the need for a DSEAR assessment and the implications from this - this needs someone with specialist competence and not something I would even think about doing myself.  Get someone in who is competent in this area of industry and work with them so that you learn rather than them just doing everything.

I am no expert but have been involved in demolishing them. Are you talking about petrol or just diesel? It makes a huge difference.

Petrol comes under the Petroleum Enforcement Authority (PEA) and a host of regulations due to its highly flammable nature. You will need the help of a specialist.

Diesel does not and the primary concern is COSHH and pollution. It also dissolves tarmac and if spilled makes most surface slippery when wet. You can get it to burn with some effort and it will act as a fuel in a fire but is a much safety to use than petrol.

I have managed a facility where we had fuel pumps serving the companies vehicle fleet and which comprised on bunded above ground diesel tanks and a 10,000 litre below ground pertrol tank.

There's a lot more to this than simply writing a good set of RAMS (including DSEAR) as staff need to be competent - I'm assuming someone there will be accepting delivery of fuels?  If so they need to be trained and have a SSoW in place.

Don't forget on-going maintenance and inspection - we used to have a situation where the fire fighting equipment was often stolen due to the pumps being on a remote part of the site.  Also internal staff treat the pumps roughly and we'd reguarly have to replace hoses etc. but our facility was quite old.

As posts above have advised if you have pertol you'll have a need for your premises to be licensed.  In my experince the local authority petroleum licencing officer will provide you with some good pointers if you ask.

This is correct except that no your site is no longer licensed but it is certified see http://www.hse.gov.uk/fireandexplosion/owner-petrol-station.htm for more details  

It was a while ago.

Chris

Most oil companies produce Diesel/Gas Oil with a spec for flashpoint of >60C so not normally classed as flammable.

There may be some, but the couple I have seen have a flash point of 56 Degrees C

also from HSE web site

Under the EU CLP Regulation there are a number of substances that now meet the criteria for classification as flammable which did not do so in the past. This is partly because the upper flashpoint for classification as a flammable liquid has been increased from 55 °C to 60 °C. The changes mean that for example, diesel, gas oil and light heating oils are now classified as flammable liquids.
