Give one reason why we said a luminous flame is safer and less likely to cause accident

Answer 1

A luminous flame is generally safer because it produces less free unburned gas and soot compared to a non-luminous flame. This reduces the risk of incomplete combustion, which can lead to hazardous situations such as the buildup of carbon monoxide or the risk of explosion. The visible glow of a luminous flame also makes it easier to monitor and control, minimizing the chances of accidental fires.
