The main purpose of a ladder is to allow people to get higher than they can reach. A ladder works by leaning it up against a solid surface and then the person climbs the ladder using the rungs.
Ladders are commonly made from materials such as aluminum, fiberglass, and wood. Aluminum ladders are lightweight and resistant to rust, making them ideal for various outdoor and indoor uses. Fiberglass ladders are non-conductive, making them safe for electrical work, while wooden ladders offer a classic design and sturdy support. The choice of material often depends on the intended use and required durability.
The three types of ladders commonly found at a worksite are step ladders, extension ladders, and platform ladders. Step ladders are self-supporting and have a hinged design, extension ladders can be extended to different heights, and platform ladders have a wide standing platform at the top for stability.
A double-cleat ladder or two or more separate ladders must be provided when ladders are the only means of access / exit from a work area with 25+ workers
Alloys of aluminum are used for making ladders because they are lightweight, strong, and corrosion-resistant. This makes them ideal for applications where a portable, durable, and low-maintenance material is needed, such as in the construction of ladders.
