Which of the following statements about fixed ladders is TRUE?

The correct choice emphasizes the requirement that any worker using fixed ladders must have specific training. This is crucial because fixed ladders, which are permanently affixed to a structure, often present unique safety hazards. Workers need to understand how to use them safely, including recognizing potential fall hazards, proper ascending and descending techniques, and the importance of using fall protection systems where required.

OSHA regulations underline the importance of proper training to ensure that workers are adequately prepared to navigate the risks associated with using fixed ladders. Such training can significantly reduce the likelihood of accidents and injuries. Safety measures and training are essential components of a workplace safety program, particularly in environments where fixed ladders are common.

While other options present different aspects of fixed ladders, they do not accurately reflect the critical aspect of worker training required for safety in their use. The adjustable nature of ladders, the specifics of safety systems reliance based on height, and the classification of ladders as portable do not align with the true characteristics and regulations governing fixed ladders.
