Find out what you should do if there's a gas or electrical emergency in your home.
We think of our homes as safe havens, yet many emergencies and accidents happen indoors.
It's therefore a good idea to find out what to do if there is a gas or electrical emergency at your property.
There are a number of things which could go wrong with your gas or electricity supply, such as an explosion, a gas leak, a fire or a power cut.
Here we take a look at some of the most common emergencies, and what you should do if they happen at your property.
Gas is used to heat millions of UK homes and to power a range of appliances. Many of us will never encounter a serious problem with our gas supply, but, if things do go wrong, it's important to know how to keep yourself and your family safe.
If you smell gas or suspect a gas leak, open windows and doors to get plenty of fresh air into your home. Make sure all appliances are switched off and, if you can, turn the gas off at the mains.
It's essential not to turn lights on or off or switch on any electrical appliances, as this could cause an explosion.
Smoking or lighting a match or other naked flame could also trigger an explosion, so make sure everyone at the property is aware of the dangers.
Call the National Gas Emergency Line on 0800-111999 and wait outside for help to arrive. Calls are free and trained operators are available 24 hours a day.
Most gas leaks don't lead to an explosion and are dealt with safely. But it's essential to follow the advice above to prevent a gas explosion happening.
Get people and pets out of the house and don't flick any electrical switches on or off. Turn off the gas appliance emitting the leak or, if possible, the mains supply, and call the emergency helpline.
Carbon monoxide (CO) is often described as the silent killer as it's colourless, odourless and tasteless yet causes up to 50 deaths each year in the UK.
Carbon monoxide poisoning can occur when gas appliances don't fully burn their fuel or when chimneys, vents and flues become blocked.
Symptoms of carbon monoxide poisoning include nausea, dizziness, headaches and tiredness. There are a number of ways to prevent poisoning, and potentially save lives, including:
This can occur when an electrical appliance, cord or extension lead is faulty or gets wet. Faulty wiring can also lead to electric shock, and shocks can range from mild to very serious.
If you're with someone who suffers an electric shock, the electricity current can pass from them to you.
Unplug the appliance or turn off the main electricity supply at the fuse box. If this isn't possible, push the electrical appliance away from the injured person with a wooden broom handle or rolled up newspaper before making contact with them.
Phone the emergency services and make them aware that you're dealing with an electrical emergency.
Once the source of electricity has been cut off, you might need to start resuscitation if the injured person is unconscious or not breathing. The 999 operator will be able to advise you on what to do.
The advice above relates to electrical incidents in the home. In a high voltage emergency - such as if you suspect a person has received a shock from overhead power cables - DO NOT approach them under any circumstances.
Keep as far away as possible and contact the National Electricity Emergency Line on 0800-404090. Warn anyone else in the vicinity to stay away and wait for an engineer and emergency services to arrive.
Be prepared for a power cut by keeping a torch or candles in a handy place in case you need them
If you lose power in your home, check your trip switch.
This should be located on or next to your fuse box and is designed to cut off the electricity supply if an appliance overheats or too many appliances are in use at one time.
If the trip switch is turned off, flick it back on and switch on all the appliances in use one by one. If the trip switch is triggered again, you will know which appliance has caused it.
In the event of total power loss, check with neighbours to see if the whole street is affected or whether it's just your property.
The number to call to report or get information about power cuts in England, Scotland and Wales is 105.
This is important to remember as many people mistakenly call their energy supplier in a power cut when they should be speaking to their local electricity network operator; the 105 service was introduced in March 2016 as an easy-to-remember number that can connect you to the people you need to talk to.
Call your supplier's emergency line to notify them and give them as much information as possible.
Be prepared for a power cut by keeping a torch or candles in a handy place in case you need them.
Make sure lit candles are secure and take extra care of naked flames if children or pets are with you. If it's cold, try to keep everyone in one room and wrap up under plenty of blankets.
Turn appliances off, keeping one light switch on so you know when the power has returned. When the power comes back on, check fridges and freezers in case the contents have defrosted.
