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!
|  |
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. |
 |
| 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. |
 |
| 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. |
 |
| 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. |
