What should be avoided during a tandem pumping operation?

In tandem pumping operations, it is crucial to avoid exceeding the rated pressure of the hose or pump. Each hose and pump is designed to operate within specific pressure limits to ensure safety and functionality. Exceeding these limits can lead to catastrophic failures, such as hose ruptures or pump damage, which not only jeopardizes the integrity of the equipment but also poses significant safety risks to personnel on the scene. Maintaining the appropriate pressure is essential for effective water flow and to prevent accidents during operations where multiple units are working together to supply water.

While the other options present considerations for a safe and effective operation, they do not highlight the immediate and critical safety implications associated with pressure limits—making understanding and adhering to these ratings a priority in tandem pumping scenarios.
