Which is NOT a characteristic of a reverse lay?

A reverse lay is a specific technique used in fire service operations where a fire apparatus moves from the fire scene to a water source, such as a hydrant. This method is typically employed to secure a water supply while keeping the pumper positioned at the hydrant for efficient connection and setup.

The option that indicates maintaining a steady water supply throughout would not typically be a characteristic of a reverse lay. Instead, maintaining a steady water supply is more associated with other laying techniques or methods where the pumper creates a continuous flow of water from the source to the incident. In a reverse lay, while the intention is to create a reliable supply once the pumper is back at the hydrant, the act of moving the pumper away from the fire incident temporarily breaks that direct flow, highlighting that the reverse lay is more about securing the connection at the hydrant first rather than maintaining a constant water supply throughout the process.

Thus, recognizing that a reverse lay involves moving away from the fire scene and then establishing a connection suggests that one might not have an immediate, steady water supply until that connection is realized and the appropriate systems are engaged back at the pumper.
