Why is coal gas poisonous?

Poisoning from natural gas appliances is only due to incomplete combustion, which creates CO, and flue leaks to living accommodation.

Why coal gas is not used for cooking?

This is because we get coal from dead plants and animals buried in the Earth’s crust millions of years ago. Fossil fuels take a lot of time for their formation. As they are not present in large quantities therefore, we cannot use coal excessively. This is the reason why we do not use coal as a cooking fuel.
