LPG (Liquefied Petroleum Gas) is kept under pressure as a liquid and when released becomes a highly flammable gas that is much heavier than air. The aim of this part of the Standards is to minimise the risk of this gas escaping into your boat's interior, where it could quickly accumulate, creating an explosive 'mix' of gas and air.
This chapter concentrates on how best to store LPG, how to supply your gas appliances and how to protect the gas system and installation from heat and impact damage.
Having main shut-off valves and appliance isolation valves to control the LPG supply, and keeping the gas system away from sources of ignition will help to reduce the risks.
Any fitter engaged in work on LPG systems on boats in scope of the Gas Safety Installation and Use Regulations must be Gas Safe registered.
