The combustion of plastics and synthetic materials commonly found in aircraft generates several harmful by-products, one of which is cyanide. When nitrogen-containing polymers are subjected to high temperatures, such as during a fire, they can release hydrogen cyanide (HCN), a highly toxic gas. This is particularly dangerous in confined spaces, such as within an aircraft, where the concentration can quickly rise to lethal levels.

Cyanide is especially concerning because it inhibits the body’s ability to utilize oxygen, leading to rapid asphyxiation and potential death. The presence of nitrogen in many synthetic materials contributes to the formation of cyanide during combustion, making it a critical hazard in the event of a fire onboard.

Understanding the specific by-products of combustion is essential for safety and emergency planning, as it can inform firefighting strategies and personal protective equipment requirements in case of an incident involving aircraft materials.
