The Boat Safety Scheme is urging boaters to avoid using portable gas camping stoves, lamps and heaters on board boats because of the risks of explosions, fire and carbon monoxide poisoning.
The alert for this summer follows yet another gas stove explosion, this time in the close confines of a tent on a North Wales campsite. The two young people inside were taken to hospital with facial burns, very similar to when two boaters were severely injured in an explosion on a boat on the Norfolk Broads in 2010
Such equipment is designed for use in open air and is not suitable for use in the limited space of a boat cabin, where both explosions and carbon monoxide would have disastrous consequences.
The Boat Safety Scheme (BSS) says boaters need to treat all such portable gas equipment with huge respect and only use such equipment when ashore in open air.
BSS manager, Graham Watts explains: "When the liquefied fuel in the canister escapes it re-forms as a gas and its volume expands 250 times, so even portable gas equipment can cause a powerful explosion, easily big enough to send people to hospital.
"The inherent risks with escaping gas, fire breaking out, or carbon monoxide in the poorly ventilated, tight confines of a boat is greatly magnified compared to the open air on land."
He advised boaters to think about the alternatives. If all you want is a hot drink aboard a day boat, a flask is probably the simplest and safest way. If you want light, the latest battery powered or wind-up LED lights will last for ages and are far easier to use than gas lanterns. Where a simple cooker is needed aboard, think about installing a marine spirit stove as an alternative to a portable gas stove.
Any boater deciding to use portable gas appliances need to be completely familiar with the correct and safe way of operation - from taking out of its storage case to fitting new fuel canisters.
These are the key safety points that can help to keep boat crews safe:
*Inland waterway regulations do not ban portable gas equipment on boats, but when not in operation, any appliance with a canister fitted and all spare gas canisters, empty or full, must be stowed in lockers that are self-draining, or on open deck areas where any leaking gas will flow overboard. The risk of causing a pool of explosive vapour inside the boat must be avoided.
