Liquefied Petroleum Gas (LPG) is commonly used onboard boats for cooking, heating, and refrigeration. While it is an efficient energy source, LPG is also highly flammable and, if not handled or used correctly, it poses a serious risk and can result in fatal consequences, including fire, explosion, or asphyxiation.
Key Safety Points:
- Ventilation is vital - Always ensure adequate airflow when using LPG appliances. Never use LPG in enclosed spaces without proper ventilation.
- Check for leaks - Regular maintenance and inspection of gas systems to identify potential problems early, and if you smell gas or suspect a leak, turn off the supply immediately and ventilate the area.
- Install a gas detector - Marine-grade LPG gas detector can provide early warning of leaks.
- Install smoke detectors and carbon monoxide alarms - Ensure they are working correctly by testing regularly.
- Turn off when not in use - Always shut off the gas supply at the cylinder when not in use or when leaving the vessel unattended.
- Professional servicing - Maintenance should only be carried out by a registered gas installer.
- Store cylinders safely - LPG cylinders should be secured upright in a well-ventilated, self-draining locker.
- Install fire extinguishers - ensure these are serviced by a competent person on an annual basis.
- Ensure you have a fire and emergency escape plan for your vessel!
Remember:
- LPG is a colourless, odourless liquid that evaporates into a gas. Normally, an odorant is added to help detect leaks.
- When released in confined spaces, it can accumulate and create a significant explosion or suffocation hazard.
- Ensure all onboard are familiar with LPG safety procedures.
- For more information, please consult your vessel’s manual or contact a certified marine gas technician.
Legislation. The following legislation sets out the safety requirements that align with the safety messaging in this Marine Notice:
- S.I. No. 79/1992 - Shannon Navigation (Construction of Vessels) Bye-Laws, 1992 & S.I. No. 247/1988 - Canals Act, 1986 (Bye-Laws), 1988 requires that LPG installations on vessels comply with Part 3 (Installations in boats, yachts and other vessels) of British Standard 5482:1979 — Code of Practice for domestic butane and propane gas burning installations.
- British Standard 5482 applies equally to vessels in Northern Ireland.
- It is anticipated that future Bye-Laws will require compliance with ISO 10239:2025 - Small craft — Liquefied petroleum gas (LPG) systems
