What is in a fire extinguisher?
Let me begin from pure chemistry, Combustion of carbon (in any form) will produce its oxides depending upon the amount of oxygen allowed to react. See, C + O2 CO2 i.e. Carbon Dioxide Also 2C + O2 2CO i.e. Carbon Monoxide Above you will see that when the amount of Oxygen is less, Carbon Monoxide is produced. i.e. in controlled environment, Carbon monoxide is likely to be produced that's exactly what happened in your case. Hope this helps.
A lightning rod (USA) or lightning conductor (UK) is a metal rod or conductor mounted on top of a building and electrically connected to the ground through a wire, to protect the building in the event of lightning. If lightning strikes the building it will preferentially strike the rod, and be conducted harmlessly to ground through the wire, instead of passing through the building, where it could start a fire or cause electrocution.
