Oxide coal Unfortunately, it is a very insidious killer. When we feel the first symptoms – headache, nausea, weakness – it is often too late. That's why firefighters and chimney sweepers constantly call for the installation of carbon monoxide detectors. How do these devices work?
What does the sensor detect?
The sensor reacts to the presence of carbon monoxide, i.e gas produced by incomplete combustion. The problem most often occurs when too little water reaches the furnace, fireplace or water heater oxygen. This happens because of clogged chimneys, covered ventilation grids or windows that are too tight.
There is a special electrochemical cell inside the sensor. It is constantly examining the air. When it detects carbon monoxide, it immediately triggers a chemical reaction that triggers an alarm. The equipment is so sensitive that it reacts even to minimal concentrations – much earlier than they would become life-threatening.
Where is the best place to place such a sensor? First of all, he must “see” the entire room. No nooks and crannies behind the wardrobe or under the curtain. It works best at eye level, i.e. about 150-180 cm above the floor.
The distance from the potential source of carbon monoxide is also important. At least two meters from the stove or stove – so that it does not falsely alarm each time you cook. But also no further than 6 meters – so that he could detect the threat.
We buy wisely
So what should you pay attention to when buying? Mainly for certificates. Good equipment must have the markings PN-EN 50291-1 and PN-EN 50291-2. It's also worth checking:
- How loud is the alarm (minimum 85 decibels)
- Will the device warn us about a low battery?
- What warranty do we have (good sensors last 7-10 years)
When the alarm sounds
First rule – don't panic. We open the windows, turn off all heating devices and go out. If anyone feels bad, we immediately call an ambulance. Down apartments We return only after airing and determining the cause of the alarm.
