What are smoke indicators used for in firefighting?

Smoke indicators play a crucial role in assessing fire conditions and behavior during firefighting operations. They help firefighters gauge the severity of the fire, its progression, and potential danger areas that require immediate attention or intervention. Observing the characteristics of smoke—such as its color, density, and movement—can provide valuable insights into the fire's intensity and whether it is spreading. For instance, dark, thick smoke typically indicates a more intense fire and the presence of materials burning, which can inform the decision-making process regarding attack strategies and evacuation routes.

Understanding fire progression is vital for not only controlling the fire effectively but also ensuring the safety of firefighters and civilians in the vicinity. Therefore, smoke indicators serve as essential tools in the firefighting process, aiding in situational awareness and tactical planning.
