What should the nozzle team do when confronted with heavy, thick, black smoke during a fire?

When encountering heavy, thick, black smoke at a fire scene, the appropriate action for the nozzle team is to open the nozzle and begin sweeping back and forth across the ceiling. This technique is important for several reasons:

First, heavy black smoke indicates that there is a significant amount of unburned fuel present, and it can be a sign that conditions are rapidly changing. By applying water in a sweeping motion, firefighters can help reduce the heat and cool the smoke, leading to a safer environment for both victims and responding personnel.

Second, this method operates under the principle of cooling the environment from the top down. Since smoke and heat rise, targeting the ceiling allows for a more effective distribution of water coverage in the upper layers of the fire environment. This helps to minimize the risk of flashover and improves visibility as the smoke begins to cool and dissipate.

Additionally, sweeping the nozzle back and forth creates a wider coverage area, allowing for better management of the fire's conditions, which is crucial in situations where visibility is compromised due to heavy smoke.

Other options presented, such as waiting for backup or assessing conditions without engaging, may lead to delays in fire suppression and increase dangers for potential victims or firefighters. Using a high-pressure mist could also be ineffective in
