Which term refers to substances produced during a fire, including flames, heat, smoke, and toxic gases?

• A. Refuge (Area of)
• B. Products of Combustion
• C. Fire Growth Hazard Potential
• D. Detection System

Answer: (B)

Substances produced during a fire are called products of combustion. This term includes everything that results from burning: the flames, the heat released, smoke, and toxic gases created by the combustion process. It’s the best fit because it directly describes the outputs of the fire, which drive safety concerns like visibility reduction, toxic exposure, and heat transfer, and influence ventilation, detection, and suppression strategies. The other options relate to safety features or risks rather than what the fire itself produces: a refuge is a safe area, fire growth hazard potential concerns how a fire might grow, and a detection system is equipment used to sense fire presence.
