What is a common hazard firefighters need to be aware of during operations?

Low visibility due to smoke and heat is a significant hazard that firefighters must be aware of during operations. When a fire occurs, the combustion process generates smoke, which can quickly fill a space and reduce visibility to near-zero levels. This creates challenges for firefighters, making it difficult to navigate and locate victims or exits. Moreover, heat can cause disorientation and can affect a firefighter's ability to communicate and respond to situations effectively.

Additionally, low visibility increases the risk of accidents, such as falling through weakened floors or colliding with other personnel or obstacles. Firefighters often rely on thermal imaging cameras and other tools to help them navigate in conditions of low visibility, but the inherent risks still require careful attention. This hazard underscores the importance of situational awareness and effective teamwork in firefighting operations.
