DID YOU KNOW THAT.........

Trading Standards is responsible for the safe storage and licensing of sites storing petrol.

Every premise that stores over 15 litres of petrol, whether it is for sale or for their own private use, must be licensed and comply with the rules for the safe storage of petrol.
(There are one or two minor exceptions).

Each year we visit places like petrol filling stations, private properties (e.g. farms, aerodromes), to inspect their storage facilities.

Did you know that you only need about 1 - 1.5% of petrol vapour (lower explosive limit) in the air to have an explosive atmosphere! One cup of petrol will produce about 5 litres of pure vapour and this will produce about 300 litres of explosive mixture at the lower explosive limit!

This is very dangerous product we regularly put into our cars!

Checking an undergound tank

We inspect petrol stations ensuring that retailers keep an accurate record of their deliveries and sales. We check that the amounts in the tanks matches what their records say they should have.

This process ensures that leaking tanks and lines are spotted promptly, to protect people from the danger explosion, highly explosive fumes and the environment from the damage the leaked fuel can cause. Officers also inspect the chambers above the tanks for signs of fuel spillage, look for water in the chambers and check for correct labelling (so the tanker driver knows he's putting the right grade of fuel in the right tank).The condition of the vent pipes and the dispensers are examined and the Officer ensures that notices and instructions are present which inform the public where the emergency switch is located, how to use the pumps, not to smoke or use mobile phones etc.

Did you know that petrol and petrol mixtures like glues and solvent based paints which are stored in cans or drums used to have to be licensed too? The vapour from petrol mixtures can be as explosive as that from petrol.

On 9 December 2002, a new set of Regulations called The Dangerous Substances and Explosive Atmospheres Regulations 2002 came in to force. These say businesses storing petrol in cans and / or drums no longer need a licence but must the must comply with the new regulations. The regulations expect each business to carry out a risk assessment and then introduce or maintain appropriate precautions to minimise the risk of a fire or explosion.

New Petrol Sites

We are also required to monitor any new petrol sites that are built or refurbished to ensure that they comply with current safety legislation and guidance.

When new tanks are being installed, a large hole is dug for the tanks; even so there is not much room to spare around the tanks, when installed there can be as little as 300mm between the tanks. The concrete base is prepared, with straps being woven through a steel mesh grid set into the concrete. As soon as the concrete has set, a base of pea gravel is laid.

Before the tanks are supplied to the site they have to be tested by the manufacturer who will then confirm that the tanks comply with EC standards and do not leak. The Petroleum Officer checks the outside of the tanks before they are lowered into the ground to ensure that the protective coating has not been damaged in transit, and watches to ensure the tanks are not damaged when lowered into the ground. new tank being lowered into place

 

Once in the ground, the tank installers begin to strap down the tanks and check that the tanks are level. This is to enable the pipe work to be fitted easily. The tanks are then are completely strapped down to ensure that they do not pop out of the ground later. Once this has been done, the tanks are set into pea gravel or concrete. tank being installed

 

The plastic pipe work has generally replaced steel pipes at new or refurbished petrol stations. The joints in the plastic pipe work are very unlikely to leak if they are made properly; so the pipe seals are all tested before the pipe work is covered with pea gravel. Plastic pipes are not subject to corrosion as the steel pipe work used to be. tanks now in place

 

The whole site is inspected for compliance before the site is licensed to store petrol. Then the firms can arrange for their first load of petrol and test the accuracy of the dispensers. pipework linking tanks
