During the inspection of metal and fiberglass ladders, what should you look for?

When inspecting metal and fiberglass ladders, looking for evidence of flame impingement or heat damage is critical because exposure to high temperatures can significantly compromise the structural integrity of the ladder. Metal ladders can weaken when exposed to extreme heat, which may not be visibly apparent until the ladder is subjected to stress. Fiberglass ladders can also be damaged by heat, as they may lose their strength or become brittle when exposed to flames or excessive temperatures. Therefore, identifying any signs of heat damage is essential to ensure the ladder remains safe for use.

Considering other aspects, cracks in the rungs, surface rust, and wear on the protective coating are also important inspection criteria but may not directly indicate immediate danger like evidence of flame exposure or heat damage. Flame or heat-related impairments pose severe risks during firefighting activities, making it crucial to focus on this factor during inspections.
