Liquefied Petroleum Gas (LPG) is a mixture of hydrocarbons, which are in gaseous state at ambient temperature and pressure but these are liquefied under pressure for easy storage, handling and transportation in pressurized vessels. It is obtained through Crude Oil refining or from Natural Gas through fractionation. Butane and Propane are the main constituent hydrocarbon's in LPG. Others present in traces or small fractions are Iso-butane, butylene, n-butane, propylene etc.

LPG is a blend of Butane and Propane readily liquefied under moderate pressure. LPG vapour is heavier than air; thus it normally settles down in low-lying places. Since LPG has only a faint scent, a mercaptan odorant is added to help in its detection. In the event of an LPG leak, the vapourisation of liquid cools the atmosphere and condenses the water vapour contained in it to form a whitish fog, which is easy to observe. LPG in fairly large concentrations displaces oxygen leading to a nauseous or suffocating feeling.

LPG is one of the safest, economical, eco friendly healthy cooking fuels for all. Besides domestic usage, LPG is often used as an efficient source of energy in various industrial and commercial applications.

If you smell gas

* Do not operate electrical switches (do not operate fan for removing the gas from the room).
* Switch OFF the pressure regulator by turning the knob clockwise to the OFF position.
* Ensure that stove knobs are in OFF position
* Do not light a matchstick even to detect the leakage of LPG.
* Open all doors and windows
* If the smell persists, call your HP Gas distributor.
* An experienced person can detach the regulator. Fix the safety cap on the valve (it too can prevent leakage of gas).

Safety tips

* Do not wear nylon garments or similar fabric when cooking
* Never leave the cooking appliance unattended when in use
* Never try to Repair, Adjust or Inspect any part of the Gas equipment. Allow authorized mechanic to inspect the installation once in two years.
* Do not use long curtains on windows if your cooking appliance is near it. They can blow over the burner and catch fire
* Insist on redelivery check of the refill cylinder at the time of its delivery
* Do not install the cooking appliance on the floor. Do not use a wooden table without asbestos sheet over it
* HP Gas should never be used in a poorly ventilated room
* Never install a Gas cylinder below ground level or in cellars or basements
* No other heating device (Like an electric oven or a kerosene stove) should be placed within one meter of a Gas appliance
* Do not use any cover on the rubber tube, rubber tube T joint connection or trolley for cylinder in your Gas installation
* Never leave the regulator in ON position after cooking is over or during night
* Always smell for leakage of LPG before lighting the stove
* Never use the rubber tube if it has cracks or is more than 2 years old

Good safety habits

* Always keep the cylinders in a vertical position with the valve on top. If cylinder is placed in any other position, liquid LPG may gush out of the open valve creating a dangerous situation.

* Not more than two cylinders should be stored in a room.

* If cylinders are placed in cupboards, these cupboards should be provided with ventilation openings both at floor level and at top level. A half gap should suffice.

* Cylinders must not be installed in any position in which they may become overheated, e.g. alongside a sigree or any other heating appliance. If any heating appliance has to be used, it must be kept at above ground height and never on floor level.

* Do not keep cylinder exposed to sun, rain, dust and heat.

* Always use BIS approved rubber tube, check for BIS mark on the rubber tube. The length of tube should be between 1 to 1.5 m.

* Don't conceal any part of rubber tube by any type of shut or cover, which obstructs the visual check along the total length of tube.

* Avoid keeping 'pooja' lamp and Refrigerator in Kitchen.

* Do not place the appliance directly in front of the window. There is a chance that a strong breeze may put off the flame causing accumulation of LPG in the room.
