Detecting Carbon Monoxide
Formula: CO
CAS Number: 630-08-0

What is Carbon Monoxide (CO)? Carbon monoxide (CO) is a colourless, odourless, and tasteless gas. It is produced by the incomplete combustion of carbon-containing fuels such as gasoline, natural gas, propane, coal, or wood. CO is highly toxic and can be fatal if inhaled in high concentrations. 200 ppm or greater will cause physical symptoms and is fatal in hours.

Health Effects of Carbon Monoxide:
CO binds to hemoglobin in the blood, reducing its ability to carry oxygen to body tissues and organs. Symptoms of CO poisoning include:

• headache
• dizziness
• nausea
• weakness
• chest pain
• unconsciousness
• death

Vulnerable populations such as infants, the elderly, and individuals with heart or respiratory conditions are particularly susceptible to CO poisoning.

Carbon Monoxide within Industrial Settings
A major origin of carbon monoxide (CO) within industrial settings arises from the burning of fossil fuels in boilers, furnaces, and power plants. These systems are frequently utilised by industries to generate heat, steam, or electricity. When fuel combustion is inadequate or there is a deficiency in oxygen supply, carbon monoxide may be generated as a byproduct. Industrial activities involving the burning of biomass, such as wood or agricultural residues, can also emit carbon monoxide into the atmosphere.

Dangers of Carbon Monoxide
This toxic gas presents serious health hazards to both humans and animals. Upon inhalation, it binds to hemoglobin in the bloodstream at a rate 220% faster than oxygen, diminishing the blood’s capacity to transport oxygen to essential organs and tissues. Consequently, this can result in oxygen deprivation, tissue harm, and potentially fatal outcomes.
