Marine gas safety check

Gas is denser than air, so in the case of a leak, it will make its way to the lowest point i.e. the bilges where it'll stay until the boat is aired to clear it or something ignites it, which may end in a big explosion.


Although LPG is potentially hazardous, it is often used quite safely if the equipment is correctly installed, well maintained, regularly inspected for damage and used carefully.

Gas bottles should be stored upright during a dedicated locker which drains overboard (to help prevent gas ending up within the bilges). The drain should be checked regularly for blockages, for instance by squirting a hose quietens the drain.


For boats which weren't manufactured with a fanatical gas locker, finding appropriate stowage for the gas bottles are often difficult. However, this needs to be done carefully to prevent accidental damage and should not be in a position which would allow leaking gas to enter the interior of the vessel i.e. located too close to hatches.


Most boats also will carry a spare cylinder which should tend an equivalent consideration because the "in use" cylinder. Although the spare cylinder is a smaller amount likely to leak, it's not impossible for it to try to so especially if it's not securely positioned and guarded from damage.


Pipes and hose must be regularly inspected to check for any wear and tear.

So regular Marine gas Safety check should be considered. Gas hose is marked with the date of manufacture and has a life expectancy of 5 to 10 years depending on the environment it is in. Don’t fit it and forget it!

Particular attention should be paid to vulnerable hose, such as where the cooker gimbals. The area behind the stove should be covered with a sheet of metal to stop accidental damage to the vessel’s hull.

Marine fuel

Marine fuel may be obtained from petroleum distillation or either distillate or a residue. In general terms heating oil is any liquid fuel that's burned during a furnace or boiler for the generation of warmth or utilized in an engine for the generation of power, except oils having a flash point of roughly 42 °C (108 °F) and oils burned in cotton or wool-wick burners. Fuel oil is formed of long hydrocarbon chains, particularly alkanes, cycloalkanes, and aromatics. The term heating oil is additionally utilized in a stricter sense to refer only to the heaviest commercial fuel which will be obtained from petroleum , i.e., heavier than gasoline and naphtha. Small molecules like those in propane and naphtha and gasoline for cars and jet fuel have relatively low boiling points and that they are removed at the beginning of the fractionation process. Heavier petroleum products like diesel oil and grease are much less volatile and distill out more slowly, while bunker oil is literally rock b...

LPG

LPG stands for Liquid petroleum gas, is a flammable mixture of hydrocarbon gases used as fuel in heating appliances, in cooking equipment, and in vehicles. It is increasingly used as an aerosol propellant and a refrigerant replacing chlorofluorocarbons in an attempt to scale back damage to the ozonosphere. When specifically used as a vehicle fuel it's often mentioned as Autogas. LPG is non-toxic but highly flammable. Therefore, LPG has got to be handled with care and every one equipment and appliances wont to store or transport the gas must suit high safety standards. They have to be maintained and regularly inspected. Trading with LPG is normally subject to government safety regulations and corresponding enforcement does prevent fire and explosion accidents. In many countries, gas is transported through pipelines which are always under the gas line inspections . LPG may be a byproduct of gas and oil extraction and petroleum refining. Around 60% of LPG stocks within the last years ...
