Generally referred to as CO and CO2, respectively, are each colourless and odourless gases that can be fatal in high concentrations. But that is wherein the similarities stop whilst evaluating CO vs CO2.
 

Carbon Monoxide
Carbon monoxide does not naturally occur within the Earth’s ecosystem and is noticeably flammable. It forms whilst fuel-burning home equipment such as fuel and kerosene heaters, oil and gasoline furnaces, fireplaces, and wood stoves are not ventilated properly. Any gas engine additionally generates carbon monoxide if it doesn’t have a catalytic converter to clear out the fumes.
CO poisoning is the most commonplace sort of fatal poisoning throughout the globe. The long-term exposure restriction installed by using OSHA is 50ppm, despite the fact that information are to be had at the link. Mild carbon monoxide poisoning occurs at ranges of 100ppm, and symptoms encompass a headache and dizziness. Exposure levels as little as 700ppm have the capability to be life-threatening.

Carbon Dioxide
CO2 occurs naturally inside the atmosphere and is necessary for plants to flourish due to the fact they require CO2 within the technique of photosynthesis. A waste manufactured from photosynthesis is oxygen, the gasoline vital for human beings to breathe. Carbon dioxide is likewise a waste manufactured from animal respiration, fermentation, and whilst fossil fuels and wood are burned. Even when the usage of a catalytic converter, gasoline engines still emit carbon dioxide. And unlike carbon monoxide, this gas is non-flammable.
It is rare for an character to get CO2 poisoning, however not impossible. The average ambient ppm for CO2 is 400ppm. For comparison, OSHA limits the place of work to 5,000ppm or less. Symptoms of moderate carbon dioxide poisoning include dizziness and headaches at concentrations of 30,000ppm. Carbon dioxide becomes life-threatening at concentrations of 80,000ppm or more.
Knowing greater approximately these two commonly harassed gases can you come up with a more perspective into how these gases exist and engage to your environment, in addition to how to keep yourself safe and healthy.
