What are the properties sources and uses of carbon dioxide?
Carbon dioxide is used as a refrigerant, in fire extinguishers, for inflating life rafts and life jackets, blasting coal, foaming rubber and plastics, promoting the growth of plants in greenhouses, immobilizing animals before slaughter, and in carbonated beverages.
Why carbon dioxide is used to put out fires density?
Carbon dioxide is denser than air. It sinks, which means that it can smother a fire – starving the fire of oxygen and putting it out. This is why many fire extinguishers contain carbon dioxide gas.

What two properties make carbon dioxide extinguishing fires?
Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.
What type of fire is carbon dioxide used on?
Carbon Dioxide is suitable for us on both Electrical and Flammable Liquid (Class B) Fire types. Being a gas it is completely harmless to electrical equipment.
What danger to personnel exists when a carbon dioxide fire extinguish?
When a CO2 extinguisher is used in a confined space there is danger that the user may become overwhelmed by the sudden increase in carbon dioxide emissions. This occurs as CO2 is an asphyxiant, and the confined space means oxygen will be replaced by the CO2 much faster.
What are the 5 characteristics of carbon?

- variety of shapes.
- bonds with multiple elements.
What are the properties and uses of carbon?
Some of the most important uses are:
- It makes up for 18% of the human body. Sugar, glucose, proteins etc are all made of it.
- Carbon in its diamond form is used in jewellery.
- Amorphous carbon is used to make inks and paints.
