Fires can release several toxic gases, depending on the materials that are burning. Here are some common toxic gases that can be produced during fires:

1. Carbon Monoxide (CO): This is a colorless and odorless gas that is extremely dangerous as it can be lethal in high concentrations. CO interferes with the body’s ability to transport oxygen and can lead to suffocation.

2. Hydrogen Cyanide (HCN): HCN is a poisonous gas that is produced when materials containing nitrogen, such as synthetics, wool, and silk, burn. It interferes with the ability of cells to use oxygen, potentially causing respiratory failure.

3. Sulfur Dioxide (SO2): SO2 is a gas produced when materials containing sulfur, such as certain plastics and building materials, burn. It can cause respiratory irritation, difficulty breathing, and other respiratory issues.

4. Hydrogen Chloride (HCl): HCl is released when materials containing chlorine, such as PVC, burn. It can cause severe respiratory irritation and damage to the lungs.

5. Nitrogen Dioxide (NO2): NO2 is produced when materials containing nitrogen burn. It can cause respiratory irritation, increase the risk of respiratory infections, and worsen asthma symptoms.

Apart from these gases, fires can also release other hazardous substances such as volatile organic compounds (VOCs), particulate matter, and soot, all of which can have detrimental effects on respiratory health.

It’s important to ensure proper ventilation and avoid inhalation of these toxic gases by promptly leaving a burning building and seeking fresh air. If you suspect a fire or are in a situation where there is a fire, follow all safety instructions and contact the relevant emergency services.
