What does the term 'reverse lay' refer to in firefighting?

The term 'reverse lay' in firefighting specifically refers to the practice of laying out a supply line from the fire back to the water source. This technique is commonly used when firefighters need to ensure that they have a reliable water supply while they are advancing toward a fire. The goal of a reverse lay is to establish a secure connection to the water supply while allowing the crew to move swiftly toward the scene of the fire.

By starting from the fire and moving towards the water source, firefighters can efficiently manage their resources and create a direct line for water access that supports their efforts in extinguishing the fire. This method is particularly effective in situations where quick response is critical, as it prioritizes the firefighters’ ability to reach and tackle the fire while also ensuring that water is readily available for use.
