Many people think that burns are the leading cause of death in fires. However, according to statistics, most fires occur with up to 50% to 80% of deaths due to smoke inhalation. 

Fire smoke and toxic gases in the fire contain highly toxic gases such as carbon monoxide, and hydrogen cyanide. The higher the fire, the longer the toxicity increases. When people inhale the toxic gas from the fire can lead to respiratory failure, loss of consciousness, suffocation, organ failure, and other effects.
