Question: 1 / 400

When using an indirect attack, what is generated by directing streams toward the ceiling?

Water vapors

Large amounts of steam

When directing streams toward the ceiling during an indirect attack, large amounts of steam are generated as water vaporizes upon encountering the high heat of the fire. The purposeful aim at the ceiling causes the applied water to absorb heat energy, transforming it into steam as it turns into vapor. This steam then travels down toward the floor, displacing heat and smoke, which can help cool the environment and reduce the flames.

This tactic is particularly effective in scenarios where direct exposure to flames might endanger the firefighter or when the fire's intensity makes a direct attack hazardous. The steam generated helps in suppressing the fire by effectively reducing the heat in the area, thus promoting better visibility and safer conditions for firefighters to proceed with their operation.
