Which firefighting technique involves the use of a specific sequence of hose advancement?

The technique known as sequential attack involves a specific sequence for advancing hose lines in order to effectively manage fire suppression efforts. In this approach, multiple streams of water may be utilized in succession to target the fire from different angles or to cover different areas systematically.

Sequential attack is particularly useful in scenarios where a fire may be spreading rapidly or when it is located in a large area. By advancing hoses sequentially, firefighters can maintain effective water application while also ensuring that the integrity of the fire situation is managed effectively. This method enhances the overall efficiency of the firefighting effort by coordinating the efforts of multiple crews or lines without overwhelming the scene or compromising safety.

In contrast, the other techniques, such as progressive attack, hose relay, and combination attack, focus on different methods of fire suppression or logistical support in hose management and do not specifically pertain to the structured sequence aspect of hose advancement as seen in a sequential attack.
