What is the recommended position angle between a ladder and the ground for stability?

The recommended position angle for a ladder to ensure stability is commonly around 75 degrees relative to the ground. This angle provides a good balance between the ladder's height and the distance from the wall or structure it is leaning against. At approximately 75 degrees, the ladder has a lower risk of slipping or tipping over, allowing the firefighter to ascend or descend safely.

When a ladder is positioned too steep or too flat, it can significantly jeopardize the stability. A steeper angle may reduce the effective base of support, increasing the likelihood of tipping backward, while a flatter angle can increase the chances of the ladder slipping away from the wall. Therefore, maintaining a proper angle of around 75 degrees is crucial for ensuring both safety and effectiveness when using a ladder during firefighting operations.
