What is LP Gas?
LP Gas (or Liquified Petroleum Gas) is derived from
2 principal sources. It is extracted with crude oil/gas from the earth,
or it is produced during the refining process.
The two most common LP gasses are Propane and Butane.
LP Gas is widely used as a domestic fuel because it is convenient, relatively
inexpensive and safe when handled correctly. As with any fuel however,
certain simple safety precautions must be observed in its use.
Characteristics of LP Gas
LP Gas is usually stored as a liquid under pressure.
When released into the atmosphere at any temperature above its boiling
point (-42oC for Propane and 0oC for Butane) it will
change from a liquid to vapour. Liquid LPG on bare skin causes frostbite.
LP Gas is heavier than air. In both its liquid and
vapour states, it is colourless and odourless. Odourising agent is usually
added to it to ensure that any leakage can be detected by smell.
LP Gas is considered to be non-toxic, but may have
some anaesthetic effect if inhaled in high concentrations.
1. When using LP Gas appliances or equipment, always
follow manufacturer's directions and maintain in a clean and undamaged
2. Before operating equipment, ensure connection
are tight. If there is any leaking, turn off and check connections. Do
not operate until leak is fixed.
3. Be aware that if a leak has occurred, LP Gas is
heavier than air and will therefore settle in low spots such as cellars
or drains. Ventilate well.
4. Do not overfill cylinders. The usual maximum filling
ratio is about 80% of volume. LP Gas expands as the temperature rises,
and unless sufficient space is available to permit this expansion, the
container could become over-pressurised.
5. Keep cylinders upright, even when empty, to ensure
the pressure relief valve can operate effectively. A cylinder lying horizontally
and involved in fire is more likely to burst.
6. Ensure that the pressure relief valve is pointed
away from the structure supporting the cylinder, in case the relief valve
operates and the discharge ignites.
7. Protect cylinders from direct sun. On extremely
hot days, if the relief valve operates, cool the cylinder with water.
8. Keep cylinders clear of rubbish or brush. Any
fire around the cylinder will increase the pressure within.
9. When using a gas barbecue or other LP Gas equipment
outdoors, be sure the area is clear and free from any ground fuel or litter
that may ignite in the event of a fire.
10. Where possible, secure portable cylinders. If
the relief valve operates, unsecured cylinders could move about rapidly
and erratically due to jet reaction.
