Basic Firefighter Written Practice Exam

Which of the following is NOT a common alternative water supply?

1. Lakes

2. Rivers

3. Underground tanks

4. Swimming pools

The correct answer is: Swimming pools

Swimming pools are generally not considered a common alternative water supply for firefighting efforts. While they can hold a significant volume of water, they are primarily designed for recreational use rather than for providing an emergency water source. Emergency responders typically rely on more structured and consistent sources such as lakes, rivers, and underground tanks, which are more predictable in terms of water availability and often equipped with means for withdrawal. Lakes and rivers are naturally occurring bodies of water that firefighters can access for suppression efforts during significant incidents. Underground tanks are specifically installed for various purposes, including emergency storage, making them reliable options for an alternative water supply. In contrast, swimming pools may not be accessible in all situations and can vary in size, location, and cleanliness, making them a less reliable choice in emergency response scenarios.
