Crowcon Blog#7: How dangerous is CO2 indoors?

Last week we looked at Carbon Dioxide from an industry point of view, so this week I think I’m going to highlight the dangers of this gas in home devices.

What is carbon dioxide?

Carbon dioxide (CO2) is the gas that the human body produces naturally. Everyone emits this gas every day to some extent. It appears naturally in the atmosphere of the earth as part of the metabolism of animals, photoatheses of plants, decomposition. This gas is colorless, odorless, tasteless, non-flammable, soluble in water and occupies less than 0.5% of our atmosphere. CO2 is classified as “greenhouse gases” and CO2 is increasingly considered one of the main causes of global warming.

How dangerous is it?

Carbon dioxide is a killer that is often ignored. Although the air always contains an amount of CO2 that we breathe in and out every day, and is completely harmless under normal conditions, CO2 that accumulates in the air will cause humans and animals to absorb less oxygen into the bloodstream and increase the level of CO2 in the blood. Will cause the body to gradually become hypoxia, leading to brain damage and even death.

Carbon dioxide indoors

The accumulation of carbon dioxide in the house is usually associated with the number of people in the house, and the concentration of gas is usually the highest when everyone is concentrated in the house. Household devices can generate more CO2, so make sure all devices are properly maintained and operated.

For example, combustion produces CO2, so that the heating device is equipped with a special chimney that leads the gas up and out of the house without leaking into the household air. Sometimes these chimneys can break down and cause CO2 to leak into the house, making the co2 rate higher in the air, which can be dangerous. To fix this, you should find a repairer and they must be qualified and the equipment must be safe. The repairer will check if there are any leaks or if your boiler system is damaged. Make sure your home is well ventilated to prevent CO2 accumulation.

When is the level too high?

Since an increase in CO2 levels will stimulate plant growth, abnormal blooms may show an increase in carbon dioxide levels. In addition, natural carbon dioxide is 1.5 times heavier than air, and so tends to “settle” in low-19ths such as basements.

Below you will see the measured levels and consider the influence:

% Air part million image enjoy
0.4 250-350 Normal concentrations in outdoor air
0.1 350-1,000 The standard concentration of space in the house with the exchange good air
0.2 1,000-2,000 Causes of fatigue and low air concentrations
0.5 2,000-5,000 Headache, drowsiness and sluggishness, loss of strength, stuffy air. Low air levels, loss of attention, increased heart rate and possible mild nausea
0.5 5,000 Workplace Exposure Limit (TWA – 8 hours)
4 >40,000 If exposed can lead to severe hypoxia resulting in permanent brain damage, coma or even death
