Gas cylinders offer an excellent energy source alternative for the 4 million off-the-grid houses in the UK, as well as providing a good backup for those powered by potentially intermittent solar and wind energy.
Whether you’re using bottled gas as your primary energy source or keeping cylinders for an emergency, understanding the basics of gas cylinder safety is essential for every homeowner to prevent accidents and ensure a secure living environment.
The Increasing Use of Gas Cylinders in Residential Environments
In areas where piped gas is not available or unreliable, gas cylinders have been rising in popularity. From powering kitchen stoves to providing heat in cold weather, these cylinders offer a versatile energy source.
As with any flammable material in or near the home, safety must always be a top priority. Neglecting proper safety precautions can lead to severe consequences, including fire, explosions, and other health risks – even carbon monoxide poisoning.
It’s crucial to be aware of the hazardous potential and implement safety measures to keep your home safe.
Key Risks of Using Gas Cylinders Indoors
Fire and Explosion Risks
One of the most significant (and obvious) risks associated with gas cylinders is the potential for fires or explosions. If a cylinder is stored incorrectly, badly maintained, or mishandled, it could start to leak gas, which, if ignited by a spark or open flame, can cause explosions.
Storing cylinders near sources of heat—such as stoves, heaters, or even direct sunlight—may increase the pressure inside the cylinder, heightening the risk of explosion.
It’s vital to ensure that gas cylinders are always kept in a cool, well-ventilated area away from any potential heat sources.
Health Risks from Gas Leaks
Gas leaks in an enclosed space can cause dizziness, headaches, and nausea, as well as potential suffocation with prolonged exposure to gas inhalation.
Additionally, a gas leak is a significant fire hazard. If enough gas has leaked into the space, a simple spark (such as turning on a light switch) has the potential to ignite the gas.
One of the most dangerous outcomes of a gas leak is carbon monoxide (CO) poisoning. CO is a colourless, odourless gas that can be deadly if inhaled in large amounts. This makes it extremely important to have a carbon monoxide detector installed in any home that uses gas as a fuel – but especially one that uses gas cylinders. Having an early alarm can be a literal lifesaver.
Is it Safe to Have a Gas Cylinder Indoors?
It depends on the type of gas.
Butane Gas you can store up to 30kg indoors (e.g. for a portable gas heater).
Remember to store any gas in a safe, responsible space, whether inside or outdoors.
Best Practices for Safe Storage
Proper Ventilation
Ensure that the area where a gas cylinder is stored or used is well-ventilated. This will help prevent gas build-up in case of a leak, reducing the risk of an explosion or health-related issues.
Accordingly, do not store cylinders in tightly enclosed spaces, such as closets or cupboards, without proper airflow.
Cylinder Placement
Cylinders should be placed in areas where they are not exposed to direct sunlight, heat, or open flames. They should also be kept away from flammable or corrosive materials.
Ensure they are positioned upright to avoid leaks. Placing them on a stable (flat) surface will reduce the likelihood of them falling over and causing an incident. Keep them away from any entry or exit points to the building.
Check that the storage environment isn’t too damp to avoid moisture building up and turning into rust on exposed areas.
Regular Inspections
Gas cylinders and their connections should be regularly checked for signs of wear, corrosion, or leaks. A simple soapy water test can help detect leaks: coat all the gas transmission gear (pipes, hoses, and valves) with soapy water and then pressurise the system without turning on an ignition source.
If you see gas leak soap bubbles or you can smell gas, you know you have a leak.
Check that the cylinder is free from dents or rust, which can prolong its lifespan and ensure safer use. If your gas cylinder does get rust, it should be safely disposed of to avoid potential mishaps.
How we can help
Gas cylinder safety is something that should be taken seriously. By following the best practices outlined above—ensuring proper ventilation, safe storage, and regular inspections—you can significantly reduce the risks associated with gas cylinder use in and out of the home.
Remember, always purchase your bottle gas cylinders from reliable suppliers. High-quality cylinders are crucial to maintaining a safe home.
By prioritising safety, you can enjoy the convenience of gas cylinders while keeping your household safe and sound.
