Your Immediate Safety Actions
If you detect the distinct smell of gas, often described as rotten eggs, in your house, your immediate priority is safety. Do not delay; swift and correct action can prevent serious incidents. The most important thing to remember is to avoid anything that could create a spark.
Turn off the main gas supply valve if you know where it is and can do so safely without using any electrical switches or appliances. Do not try to find the source of the leak or fix it yourself. Your aim is to get everyone out and alert the professionals.
- Leave the property immediately.
- Do not use electrical switches or appliances.
- Do not light matches or lighters.
- Call the gas emergency service from outside.
When You Smell Gas
Imagine the scenario: you're making dinner, or settling down for the evening, and that unmistakable sulphurous odour wafts through the air. It’s a chilling moment. The first, most critical step is to evacuate everyone from the premises. Don't worry about collecting belongings; your life and the lives of your household are paramount. As you leave, open doors and windows on your way out to help ventilate the property, but do not linger to do so.
Once you are a safe distance away from your home – preferably at a neighbour's house or well down the street – use a mobile phone or a neighbour's landline to call the national gas emergency service. They are equipped to handle these situations and will dispatch engineers to investigate and make the area safe.
Never underestimate the danger of a gas leak; it is a serious emergency.
Why Prompt Action is Vital
Understanding the Risks
Natural gas itself is odourless, but suppliers add a chemical called mercaptan to give it that characteristic rotten egg smell. This is a safety measure, allowing us to detect leaks easily. Escaped gas can accumulate in enclosed spaces, and any spark – from an electrical appliance, a light switch, a mobile phone, or even static electricity – could ignite it, leading to a dangerous explosion or fire.
Beyond the immediate explosion risk, prolonged exposure to gas can also lead to health issues, though this is less common than the fire hazard. The primary concern remains the ignitable nature of leaked gas. This is why the advice to avoid electrical devices and open flames is so consistently stressed.
The odourless nature of pure natural gas makes mercaptan essential for early detection.
Gas Safety Devices
While immediate evacuation and professional help are non-negotiable, having the right safety equipment at home can provide an earlier warning. A carbon monoxide alarm is different from a gas leak detector, but many homes benefit from both. Battery operated carbon monoxide detectors, or those powered by mains electricity with battery backup, can alert you to dangerous carbon monoxide fumes from faulty appliances. For detecting the smell of gas itself, specific gas leak detectors are available, but they are not a substitute for vigilance and professional checks.
Ensure any gas appliances, including boilers, ovens, and fires, undergo an annual gas safety check. This regular maintenance by a qualified professional helps identify potential issues before they become dangerous leaks.
After the Emergency is Over
When Professionals Have Assessed the Situation
After the gas emergency service has attended, assessed the situation, and declared your home safe, it’s time to consider the next steps. If the leak was from an appliance, you will likely need to arrange for it to be repaired or replaced by a qualified Gas Safe registered engineer. Do not attempt to use any appliance that was identified as the source of the leak until it has been fixed and tested.
Keep the contact details for your local gas emergency service and Gas Safe registered engineers readily accessible, perhaps near your main fuse box or on a kitchen noticeboard, so you can find them quickly if needed.
Preventative Measures and Checks
To prevent future incidents, ensure all your gas appliances are serviced regularly. A boiler service and gas safety certificate is a legal requirement for landlords, but all homeowners benefit from this peace of mind. It confirms your boiler is functioning safely and efficiently. When purchasing new appliances, always ensure they are installed by a qualified professional.
Consider the best location for carbon monoxide detectors within your home; they should be installed on every level, especially near sleeping areas. While these do not detect the 'rotten egg' smell of natural gas leaks, they are critical for detecting the silent, deadly gas, carbon monoxide, which can be produced by faulty combustion in gas appliances.
Regular checks and professional servicing are key to maintaining a safe gas supply.
