Every year the fire and rescue service is called to over 600,000 fires which result in over 800 deaths and over 17,000 injuries. About 50,000 (140 a day) of these are in the home and kill nearly 500 and injure over 11,000, many which could have been prevented if people had an early warning and were able to get out in time. In fact you are twice as likely to die in a house fire that has no smoke alarm than a house that does.
Buying a smoke alarm could help save your home and the lives of you and your family.
What are smoke alarms?
Smoke alarms are self-contained devices that incorporate a means of detecting a fire (smoke detector) and giving a warning (alarm), usually a very loud beeping sound. They are about the size of a hand and are normally fitted to the ceiling. They can detect fires in their early stages and give you those precious minutes to enable you and your family to leave your house in safety.
What type of smoke alarms are available?
There are mainly four types of smoke alarm currently on the market – ionisation, optical (also described as photo electronic), heat and combined.
Ionisation: These are the cheapest and cost very little to purchase. They are very sensitive to small particles of smoke produced by fast flaming fires, such as paper and wood, and will detect this type of fire before the smoke gets too thick. They are marginally less sensitive to slow burning and smouldering fires which give off larger quantities of smoke before flaming occurs. They can also be too over-sensitive near kitchens.
Optical: These are more expensive but more effective at detecting larger particles of smoke produced by slow-burning fires, such as smouldering foam-filled upholstery and overheated PVC wiring. They are marginally less sensitive to fast flaming fires. Optical alarms can be installed near (not in) kitchens, as they are less likely than ionisation alarms to go off when toast is burned.
Heat Alarms: They detect the increase in temperature from a fire and are insensitive to smoke. They can therefore be installed in kitchens. They only cover a relatively small area of a room, so potentially several heat alarms need to be installed in a large kitchen.
A carbon monoxide (CO) alarm should be fitted in any home that contains a fuel burning appliance, like a boiler, and tested regularly to ensure that it is working.
What is carbon monoxide (CO)?
Carbon Monoxide (CO) is a colourless, tasteless and odourless gas that can cause harmful and potentially fatal effects.
Carbon monoxide is produced by the incomplete burning of fossil fuels, such as gas. This can occur in inadequately maintained or badly fitted domestic heating appliances, such as boilers and gas fires. If your flue or chimney is blocked, CO will be unable to escape your home if produce, allowing a dangerous concentration to quickly build up.
If carbon monoxide escapes into your home it will cause symptoms that include headaches, breathlessness, drowsiness, vomiting, chest pains, dizziness, vision problems and eventually collapse and loss of consciousness – which can easily be confused with, or misdiagnosed as, flu, fatigue or food poisoning. Be aware of the symptoms and be prepared to react if you recognise them in yourself or others.
