Aims and objectives

At the end of this activity, you should be able to:

1. Define the different types of gas used to supply appliances in domestic dwellings
   
2. Identify the combustion process with gases used in dwellings
   
3. Identify the potential effects of carbon monoxide when incomplete combustion takes place
   
4. State typical ambient levels of carbon dioxide, identify critical levels and the potential effects on the gas combustion process.
   
5. Describe the types and locations of Carbon Monoxide detectors
