What is a key factor when determining the safety of ladder angles?

When determining the safety of ladder angles, the angle of inclination is a key factor because it directly affects the stability and safety of the ladder while in use. The recommended ladder angle is typically around 75 degrees from the ground. This angle ensures that the ladder is stable enough to support weight without slipping or tipping over while in use.

A proper angle prevents the base of the ladder from sliding out and the top from falling inward, which can lead to falls or accidents. Ensuring the correct angle of inclination also helps distribute the load evenly across the ladder, maximizing its structural integrity and safety.

While the height of the ladder, the weight of the user, and the material of the ladder all contribute to overall ladder safety, the angle of inclination plays a crucial role in establishing a firm foundation for safe use.
