differentiate between co2 and co
Answers
Answer:
About Carbon Monoxide
CO is produced naturally in trace amounts by the partial oxidation of methane in the atmosphere, volcanoes and forest fires
CO is produced at dangerous levels by oxygen-starved combustion in improperly ventilated fuel-burning appliances such as oil and gas furnaces, gas water heaters, gas ovens, gas or kerosene space heaters, fire places and wood stoves
CO is produced at dangerous levels by internal combustion engines that DO NOT use a catalytic converter
It is the most common type of fatal poisoning in the world
CO Recommended Levels
0.1 ppm is the current average CO level on the planet
OSHA limits long-term workplace exposure levels to 50 ppm (parts per million)
Symptoms of mild CO poisoning include headaches and dizziness at concentrations less than 100 ppm
Concentrations as low as 700 ppm can be life-threatening
About Carbon Dioxide
CO2 is a common gas in the atmosphere, and is required for plant life
CO2 is a natural byproduct of human and animal respiration, fermentation, chemical reactions, and combustion of fossil fuels and wood
CO2 is non-flammable
CO2 is generated by internal combustion engines that DO use a catalytic converter
CO2 poisoning is rare; however scuba divers have to watch out for it (the bends)
Leaking pressurized CO2 tanks in enclosed areas can be dangerous for occupants - both from high levels of CO2 and from relatively lower levels of oxygen (displacement)
CO2 Recommended Levels
400 ppm is the current average CO2 level on the planet
ASHRAE recommends a 1,000 ppm limit for office buildings and classrooms
OSHA limits long-term workplace exposure levels to 5,000 ppm
Drowsiness can occur at 10,000 ppm – common in closed cars or auditoriums
Symptoms of mild CO2 poisoning include headaches and dizziness at concentrations less than 30,000 ppm (3%)
At 80,000 ppm (8%) CO2 can be life-threatening
What are the similarities between CO and CO2?
Carbon and oxygen combine to form both gases
Both are colorless, tasteless and odorless
Both are in the air worldwide (albeit in different concentrations)
Both are released during combustion or fire
