10.7 Liquified/Liquid Petroleum Gas (LPG)

Additional reference material:

It is essential that all installation and any planned maintenance or repair work is undertaken by a qualified technician to an approved standard - (ISO 10239:2014 Small Craft – Liquefied Petroleum Gas (LPG) Systems), and in accordance with the manufacturer’s instructions.

10.7 Liquified/Liquid Petroleum Gas (LPG)

The following safety devices should be fitted to any LPG system:

Many recreational craft are fitted with Liquid Petroleum Gas (LPG) installations and appliances, primarily in the form of cookers. LPG is supplied in pressurised cylinders and is usually propane, butane or a mixture of the two gases.

▪Manual Isolation valve on the

cylinder;

▪Fixed pressure regulator located

within the storage locker to provide a fixed working pressure to the consuming device;

When handled incorrectly, the dangers associated with LPG systems include fire, explosion, burns and asphyxiation, due to gas leakage from the system or accumulation of gas following flame failure in an appliance. Such incidents have caused loss of life and material damage on recreational craft.

▪A pressure relief device located on

or adjacent to the cylinder;

▪An automatic safety gas cut out

device located on the cylinder or adjacent to it, to cut off the gas supply in the event of a loss of pressure due to a gas leak;
