People can injure themselves in many ways. Some do not respect fire and think they will be fine. Smoke is a killer. People think they can go through it. Think about when you are at home and you have a bonfire. The wind changes direction, you lose your vision, and you close your eyes: the smoke is an irritant. Your eyes water, and you become disorientated. In a fire, you are at risk and can easily become a victim of smoke by getting lost or going the wrong way. As the smoke gets into your lungs, your respiration is affected and you can soon become unconscious.
