What does smoke consist of during a fire?

During a fire, smoke is comprised of a complex mixture of various gases, vapors, and solid particles. This composition stems from the combustion of different materials present, which can include organic matter, plastics, and other substances that release not just gases but also particulates and aerosols.

Carbon dioxide, water vapor, carbon monoxide, and numerous other chemicals, including volatile organic compounds and potentially harmful toxins, are all constituents of smoke. Each fire is unique depending on the materials burning, making smoke composition varied and complicated.

Understanding that smoke is not just a single substance but rather a diverse blend helps to grasp the dangers it poses in terms of inhalation hazards as well as its role in reducing visibility and complicating fire response efforts. This awareness is essential for effective fire safety management, especially in high-rise situations where smoke can travel rapidly through air shafts and corridors.
