The use of these materials facilitates the deployment of ladders for firefighting, but it also brings with it certain pitfalls. During the use of ladders in extinguish-ing fires, their thermal influence and subsequent changes in mechanical properties may occur. This is highly dangerous and can lead to people falling from these ladders due to a significant reduction in the mechanical properties of the material.
