Research has revealed that householders are four times as likely to be killed by fire in a house that does not have an alarm when compared to a property that has one installed.
Although deaths from carbon monoxide poisoning are not as common as those caused by fire, the number of fatalities is still too high and these deaths are easily preventable.
Thankfully, it seems that many householders are starting to fully realise the potential dangers posed by not having detector alarms for fire, smoke and carbon monoxide fitted in their properties.
There are quite a few people who never even think about carbon monoxide, even though it injures thousands of people each year.
Before installing any of these detector systems in a property, it is advisable to know exactly what each alarm does, where it should be placed and any laws which govern their use in landlord-owned properties and new-builds.
Carbon Monoxide Detectors
Carbon monoxide (CO) poisoning is known as the silent killer for a reason. The gas is colourless, odourless and tasteless. It is impossible to tell if a gas appliance in a property is leaking carbon monoxide without the aid of a detector.
People do not know they are suffering from CO poisoning until it is too late.
Even if the poisoning is not at a high enough level to kill, it can still cause breathing problems for the rest of a person's life.
Gas appliances which do not burn fuel properly produce excess carbon monoxide, which is then let loose into the atmosphere. Audible carbon monoxide alarms detect the presence of the excess CO and warn residents accordingly.
Although they are simple to install, carbon monoxide detectors should be fitted as per the manufacturer's instructions and serviced accordingly to avoid any potential warranty issues.
If a single alarm is being installed, it should be placed near to the main sleeping areas to ensure it can be heard by occupants if it goes off. When more than one alarm is to be fitted, one should be placed near sleeping areas while others should be placed near to potential sources of carbon monoxide.
If fitted on a ceiling, the alarm should ideally be at least 300mm away from light fittings or walls.
Smoke and Fire Detectors
This is the most common type of detector is that used to detect smoke and fire.
It is important to remember that smoke detectors have a shelf life of between 5 and 10 years.
There are four main types of smoke and fire detectors:
Ionised Smoke Alarms
Ionisation, optical, heat and combined. Of the four, ionisation alarms are the least expensive. They are very sensitive at detecting smoke from fast-burning flames but less effective with slow-burning fires.
Optical Smoke Alarms
Optical alarms may be more expensive but are far more adept at detecting large particles of smoke from slow-burning fires. Unlike ionisation models, optical alarms can be installed near kitchens, as they are less likely to be triggered by smoke from burnt food.
If a householder wants an alarm fitted in their kitchen, the best type for these situations is the heat alarm. This type of detector is not sensitive to smoke and works by recognising a significant rise in temperature instead, such as that caused by a fire.
Combined alarms are simply combinations of detectors, such as ionisation and optical models.
For maximum protection, it is advised that each room in a property should have a smoke detector installed. However, this is not always practical, so a good rule of thumb to go by is to at least ensure that each floor of a property has an alarm fitted. In these cases, a combination of ionisation and optical alarms works best.
As with kitchens, bathrooms should only be fitted with heat alarms. Any other type of detector will be triggered by the presence of steam, leading to constant false alerts.
In landlord-owned properties where there are a number of different tenants, fire detection systems which are capable of waking sleeping people have to be in place by law. This usually requires the presence of interlinked mains-powered smoke or heat alarms that are fitted with a battery back-up.
The fitting of alarms which detect smoke, fire and carbon monoxide is a simple process and could lead to precious lives being saved; there really is no excuse for not fitting them in properties!
