In Canada having a smoke and carbon monoxide detector is the law and the reason why is simple, it saves lives.
Dangers of Smoke
Many home fires start at night and if there is no smoke detector those asleep in the house will not know the notice the file and will be overwhelmed. By having a working smoke detector you can stay safe and also awake the family before the situation gets much worse.
Dangers of Carbon Monoxide
Carbon Monoxide is a colorless, odorless, and tasteless gas that kills, unless detected early. CO kills by displacing the oxygen in your blood. The Human Body requires oxygen for the burning of fuel (food) to provide it with the energy that allows our cells to live and function.
With Carbon Monoxide is has symptoms similar to the flu. fatigue, headaches, dizziness, vomiting and shortness of breath. After a few minutes you black out and it usually results in serious and possible permanent damage to the body. Eventually carbon monoxide inhalation will lead to death. So having that carbon monoxide detector working can alert you and keep your family safe.
Types of Smoke Detectors
An ionization type smoke detector is better at detect fast, flaming fires. The fires usually make up nearly three-quarters of home fires.
A photoelectric type smoke detector is better at detecting slow-burning smouldering fires that produce a lot of smoke but little flame.
