What is the term for laying a supply line from the fire to a water source?

The term for laying a supply line from the fire to a water source is referred to as a reverse lay. This technique involves extending the hose line from the location of the fire back toward the water source, ensuring that firefighters have a reliable and efficient way to connect to a hydrant or another water supply while advancing towards the fire.

Using a reverse lay allows firefighters to establish a continuous supply of water without the need to break the connection once they reach the water source. This is critical in maintaining pressure and flow as they combat the flames. It is especially useful in situations where quick and efficient deployment of water is essential for fire suppression.

The other options, while related to hose lays, describe different methods or scenarios that do not specifically refer to the action of laying a supply line from the fire to the water source. Therefore, understanding the application and terminology of the reverse lay is vital for effective firefighting operations.
