What capacity should be considered when performing a reverse lay?

When performing a reverse lay, it is crucial to consider all aspects of capacity—water, static, and pressure—because each factor plays a significant role in the effectiveness of the operation.

Water capacity pertains to the volume of water available from the supply source and the flow rate that can be maintained. When laying a supply line, knowing the water capacity ensures that sufficient flow can be established to meet the demands of firefighting operations.

Static capacity refers to the potential water supply available from sources like hydrants or tanks when no water is being drawn from them. Understanding static pressure helps in determining the reliability of the water source and its ability to provide adequate pressure when needed.

Pressure capacity is the measure of how much pressure can be sustained throughout the supply line, especially when several hoses are connected and demanding water from the same source. The pressure must be monitored to ensure that it remains within operational limits to avoid equipment failure and ensure consistent water delivery to the firefighting efforts.

In summary, all these capacities—water, static, and pressure—are interrelated and essential for establishing an effective reverse lay. Each component must be accounted for to ensure that the engine company has adequate resources and can maintain operational effectiveness during firefighting operations.
