Liquified petroleum gas (LPG) is an invaluable source of energy on many sailing vessels. It should, however, be used with great care.
In its gaseous form it is heavier than air and will always collect at the lowest level in a vessel. Any leak of gas, any spillage of liquid could sink to the bilge and, unable to escape, build up to explosive proportions. The Nasa gas detector system warns if the level of LPG rises above 10% of the lowest explosive limit (LEL) giving adequate warning of the need to ventilate the area before a dangerous situation occurs.
The system consists of a cabin mounted monitor and a remote sensor. The monitor gives visual and audible warning if gas levels at the sensor rise above 10% LEL and will warn of fault conditions such as damaged cables etc. There is also an auxiliary output to drive external devices. The splash proof sensor is supplied with a 5 metre cable and has a test button to check the system right through to the gas sense element. The sense element is user replaceable in the event of contamination.

We cannot predict the cost to ship hazardous materials outside of UK. If your purchase includes a gas inflating lifejacket we can send it overseas only by first removing the gas bottle. You will have to find a local source to replace this bottle for the lifejacket to function. We cannot send re-arm kits overseas.
We cannot send other hazardous goods including liferafts, paint and antifouling overseas without first getting a special delivery quotation. After all these hurdles we put up, please do not be alarmed - if you need a liferaft delivered to the Baltic, the Mediterranean, the Caribbean, simply contact us for a quote. You can be confident our delivered price will still be better than local sourcing.
For delivery outside the EC, you must observe and comply with all applicable regulations and legislation, including obtaining all necessary customs, import or other permits to purchase goods from our site.

Storrar Marine Ltd make no representation and accept no liability in respect of the export or import of the goods you purchase.
