What is the maximum recommended angle for setting an aerial ladder?

The maximum recommended angle for setting an aerial ladder is 70 degrees. This angle promotes optimal stability and reach when deploying the ladder. At this angle, the ladder provides a good balance between height and safety, ensuring that it can support the weight of personnel and equipment without compromising structural integrity.

Setting the ladder at this angle helps prevent the ladder from becoming too steep, which may increase the risk of slipping or falling, or too shallow, which could lead to inadequate reach or stability. The 70-degree angle is widely recognized as a standard in firefighting and emergency response, ensuring that crews have a safe and effective means of accessing elevated areas.

Other angles, while they may seem effective at first glance, either do not offer the same level of safety and control or could introduce risks during high-stress situations. Thus, the 70-degree angle is essential for maintaining safety protocols and operational efficiency for firefighters using aerial ladders.
