What is LPG?
LPG is a liquid petroleum fuel. LPG is a mixture of Butane and Propane,
which is gaseous at normal temperature and atmospheric pressure. However for convenience
in handling, transporting and storage, it is converted into a liquid form bapplication
of moderate pressure. The cylinder contains a liquid which vapourises at normal
atmospheric pressure, and what comes out at the burner head is then gas, which
you ignite with a match-stick.
Typical Smell of LPG
LPG in its pure component form is odourless. However to make it easily
detectable when leaking, a compound called Mercaptan Sulphur is added in such quantities
that even at 1/5 th level of the lower explosive limit, the foul smell will be detectable,
and you will be impelled to set about correcting it. LPG is colourless as well.
LPG is not dangerous
LPG is no more dangerous than any other fuel. As long as you follow the
simple and basic procedures in its use it is safe, in fact, far safer as compared to other
conventional fuels. LPG will ignite only when air is mixed with it in certain proportions
called the explosive range, which is very narrow. LPG does not ignite, therefore certainly
cannot explode, beyond this range.
LPG is heavier than air
LPG vapour is nearly twice as heavy as air. In case of a leakage,
it would tend to settle at the ground level, which necessitates adequate ground level
ventilation where LPG is stored. LPG is lighter than water, hence would float on it.
LPG Marketing in India
In effect is a combination of the 3 'C's convenient, clean and perhaps
the cheapest fuel available today.
The demand and supply balance has tipped in favour of demand, which continues
to outstrip supply (which is re-stricted due to limited indigenous availability and import restrictions).
In order to bridge the demand-supply gap, the Government has decanalised LPG imports, thereby allowing
the private sector to actively participate in the import and marketing of LPG in India.
For domestic users, it is subsidised by the Government in view of its
For our industrial and commercial users, an import parity price is being
charged effective 1.10.96., which entails price revisions on a monthly basis.
Various types of cylinders being marketed by the PSU Oil Companies
There are 3 types of cylinders being currently marketed - the 14.2 kg, 19 kg and
47.5 kg capacity.Domestic users and exempted category of commercial users are supplied the 14.2
kg cylinders, while the 19 kg and 47.5 kg cylinders are meant exclusively for commercial and
industrial use.These cylinders are manufactured only by the approved manufacturers, under the
supervision of BIS inspectors and are certified by the Controller of Explosives. While all
cylinders are spray painted with a signal red Colour, BPC cylinders have a yellow ring around
the bung, HPC cylinders a blue ring, and IOC cylinders are fully red. In case of the 19 kg
cylinders, the top is painted olive green.The cylinders carry their complete history with
regard to their serial number, tare/gross weight, water capacity, ISI monograms,
test dates,manufacturer's identification and year of manufacture.
