How often should ground ladders be service tested?

Ground ladders should be service tested yearly while in service and after each use to ensure that they remain in optimal working condition and meet safety standards. Regular testing is crucial because ladders are subjected to a variety of stresses during use, including exposure to the elements, physical wear and tear, and potential damage from environments encountered during firefighting operations.

Yearly testing allows for the identification of any hidden defects, weaknesses, or material degradation that may not be immediately obvious. This routine ensures that firefighters can rely on the ladders during emergencies, as a compromised ladder could lead to serious accidents or injuries. Testing after each use is equally important to catch any damage that may have occurred during a specific incident, ensuring safety for future operations.

The other options suggest less rigorous or inconsistent testing intervals, which would not provide the necessary assurance of ladders' safety and functionality during critical firefighting operations. Regular and systematic testing is a fundamental aspect of maintaining firefighting equipment.
