True or False: Laying dual 3" supply lines should be considered based on fire size and building construction.

Laying dual 3" supply lines is indeed a strategy that should be considered based on factors such as fire size and building construction. When assessing a fire situation, the intensity of the fire and the type of structure involved are crucial in determining the adequacy of water supply. Larger fires or those in substantial buildings may require greater water flow to effectively combat the blaze.

Using dual supply lines can provide a more reliable and abundant water source, enhancing the firefighting effort. For instance, if a fire is large and in a commercial structure, which often has considerable fire loading and may spread quickly, establishing dual lines ensures that firefighters have the necessary water supply to address the emergency effectively, preventing the fire from escalating further.

In essence, the choice to lay dual supply lines enhances the ability to manage the incident, ensuring that resources are aligned with the specific demands of both the size of the fire and the complexity of the building involved, making this approach a sound tactical decision.
