What does smoke primarily consist of?

Smoke primarily consists of water vapor and airborne particles. When materials burn, they produce a variety of byproducts, but the most significant components of smoke are fine particulate matter and moisture. These particles can include soot, unburned fuel, and other combustion byproducts, while water vapor is generated from the combustion process as well.

Understanding this composition is essential for fire and life safety educators, as it helps in communicating the dangers associated with smoke inhalation and the potential health risks it poses to individuals within a structure during a fire. Smoke can obscure visibility, irritate respiratory pathways, and carry toxic substances, making it crucial to address the importance of smoke detection and the need for evacuation plans to minimize exposure.
