In the wake of the artist’s death Nevin MandourAs a result of a fire accident in her home in Alexandria this morning, the question may arise: How can smoke resulting from a fire take a human life? There are many scientific answers that could save thousands of lives before fire accidents occur.
How does inhaling smoke from a fire lead to death?
According to what was published by the US National Library of Medicine, experts revealed details about… What is smoke inhalation? It is breathing gases and materials released by combustion (smoke) inside a fire, and it is considered one of the most fatal causes of fire-related accidents, even more than the burns themselves.
Experts confirmed that smoke is considered fatal because it is a mixture of heat and toxins, as it contains toxic gases such as carbon monoxide (CO) and hydrogen cyanide, fine particles that stick to the lungs, and high heat that causes direct damage to the respiratory system. They explained that carbon monoxide is a colorless and odorless gas, but it sticks to hemoglobin in the blood with a stronger force than oxygen, which prevents oxygen from reaching vital cells in the body, and leads to hypoxia and then organ failure.
Experts added that injury to the airway and lungs is the most prominent cause, as smoke inhalation injuries are divided into three types according to the location of the damage:
1. Thermal injury to the upper airways, where heat causes direct damage to the cells lining the respiratory tract.
2. Chemical injury, while the toxic compounds in smoke cause widespread irritation and inflammation in the respiratory system.
3. Systemic toxicity: Gases are absorbed into the blood and cause damage to multiple organs, especially the brain and heart.
How does smoke cause death?
Experts continued that smoke causes death as a result of airway obstruction, heat and inflammation cause swelling and narrowing of the bronchi, which impedes the entry of air, and toxic particles are deposited in the lungs and obstruct oxygen exchange, in addition to lack of oxygen, as carbon monoxide poisoning reduces the ability of the blood to transport oxygen to the tissue, and the lack of oxygen reaching the cells leads to failure of the functions of vital organs such as the brain and heart, and fainting and death may occur quickly.
and acute inflammation of the lungs, where chemical compounds cause a severe inflammatory response in the lung tissue, leading to pulmonary edema and difficulty breathing.
Experts pointed out that there are possible indicators of death after exposure to smoke, most notably:
• Severe difficulty breathing or stopping breathing
• Rapid loss of consciousness
• Blue/gray skin color due to lack of oxygen
• Diagnosis of carbon monoxide poisoning in the blood
Usually, in severe accidents, death occurs quickly without rescue if the person is not removed from the source of smoke and provided immediate oxygen.
Smoke inhalation is one of the most dangerous fire hazards, because it contains toxic gases that prevent oxygen from reaching the body, and causes direct injury to the lungs, pushing the body toward respiratory failure and rapid death.
Experts revealed prevention methods through installing fire and smoke alarms, quick evacuation plans, and education about the dangers of smoke and how to deal with them.
