Sievert AB on LP gas
|
| |
|
Gaseous paraffins is the
correct description what we call LP gas. LP gas consists of the hydrocarbons
propane and butane, or a mixture of the two. These gases are extracted from
crude oil. LP gas or LPG stands for liquefied petroleum gas. At normal
temperatures, LP gas is gaseous but is a liquid when under pressure. Propane
must be distributed in steel cylinders that can withstand high pressure.
Butane can be distributed in lighter gas cartridges. |

LP gas and safety |
| |
|
Leaking LP gas is a fire hazard. |
|
LP gas is heavier than air. |
|
LP gas uses air during combustion. |
| |
|
There are primarily two
things to think about to prevent accidents with LP gas. 1. Avoid leakages.
2. Ensure good ventilation. Leaking LP gas can ignite and cause a fire, or
in the worst case, an explosion. The cylinder valve should always be closed
when the cylinder is not in use. The cylinder should be stored upright and,
if possible, at ground level since LP gas is heavier than air and can
therefore accumulate in cellars, manholes etc. Good ventilation is important
when working indoors as the flame consumes air. Lack of oxygen causes
incomplete combustion, which produces carbon monoxide instead of carbon
dioxide. Carbon monoxide is a treacherous and deadly gas. |

LP gas and efficiency |
| |
|
Permits very high power outputs.
|
|
Energy content is high. |
|
Fuel is easy to store and transport. |
| |
|
A large amount of fuel only
occupies a small space and is therefore easy to store and transport. LP gas
forms a combustible mixture with air when the proportion of gas is between 2
and 10 percent. When the gas changes from a liquid to a gaseous form, the
volume increases by 250 times. In other words, the energy content is high.
LP gas can be stored in its container almost indefinitely without the gas
breaking down. |

| |
|
LP gas and the environment
|
| |
|
LP gas is non-toxic and does not contain
hazardous additives. |
|
It does not contaminate air or water.
|
| |
|
LP gas does not produce any
hazardous combustion gases, just carbon dioxide and water vapor. The gas
does not contaminate water, it does not produce soot, it is not corrosive
and it does not cause corrosion to iron or other metals. It does not contain
lead or heavy metals and is non-toxic. In other words, LP gas is an
environmentally friendly fuel. The only additive is a strongly smelling
substance that acts as a warning signal for leaking gas. Normally, LP gas
has no smell. |
| |
| |
|
LP gas and handling |
| |
|
Work in well-ventilated areas. |
|
Avoid placing the LP gas cylinder near sources
of heat. |
|
Ensure that the cylinder is stored upright during transport. |
| |
|
You should regularly check
valves and connectors for leakage. Remember also that good ventilation is
important at areas where the gas is stored or used. Ventilation is also
important to ensure effective combustion. Make sure that the cylinder is at
ambient temperature when you begin working. If you are going to use the fuel
at temperatures below 32°F, use propane instead as butane does not
gasify at low temperatures. |
| |
| |
|
LP gas and fire |
| |
|
Always extinguish LP gas fires with powder,
never water. |
|
Move LP gas cylinders to a safe place if there
is a fire in the vicinity. |
|
If possible, close the valve on the cylinder. |
| |
|
Steel cylinders are fitted
with a safety valve that opens if the pressure increases too much. This can
occur if there is a fire close to the cylinder. The valve stops the cylinder
exploding. To guarantee the function of the safety valve, it is important
that the LP gas cylinder is stored in a standing position. In addition, a
closed valve stops unchecked gas flow if a hose should become damaged. |

|
LP gas and equipment
|
| |
|
Never allow an untrained person to use the
equipment. |
|
Only use special LP gas parts. |
|
Be extra careful with valves and connectors. |
| |
|
Never use other valves, burners or hoses than those designed for use with LP gas. Sievert LP gas hose conforms to the EN 559
standard. The hose consists of an internal rubber layer that is LP gas-proof,
armouring an external rubber layer that can withstand air and aging. All
equipment shown in this product catalogue is manufactured of materials that
withstand LP gas and is designed so that the risk for leakage is minimal.
|
| |
| |
| LP gas and checks |
| |
|
Ensure that you have the correct equipment for
the job. |
|
Make sure that you have tightened all valves
and connectors.
|
|
Regularly inspect the equipment and check that the system is sealed. |
| |
|
Read the instructions for
use and follow the safety advice. Use soapy water or a special liquid for
detecting leakages on valves and joints to find any leaks. LP gas hoses
should be checked very carefully and changed if you see any changes. Bend
the hoses and look for cracks in the rubber. Hoses exposed to sunlight with
age quicker than those used indoors. |
| |
| |
|
LP gas and storage |
| |
|
LP gas is not affected by long storage periods. |
|
Always disconnect equipment form the container. |
|
Store the cylinder in a well-ventilated area. |
| |
|
Avoiding storing LP gas
cylinders in areas that are warm. Temperatures below zero Celsius are,
however, perfectly safe for storage. Ensure that the ventilation is good. In
principle, LP gas can be stored indefinitely in its container without the
quality being affected. Remember to remove all connectors before storing the
equipment. To empty the system of gas, close the valve on the LP gas
cylinder. Then close any valves on the rest of the equipment. In this way,
you will avoid LP gas spillage when you open the system again. |
