What does the 75-80-80 rule apply to in fire operations?

The 75-80-80 rule pertains specifically to the operational guidelines for extended reach devices such as aerial ladders. This rule focuses on the optimal angles for setting up aerial ladders to ensure safety and maximum effectiveness during operations. According to this rule, the ladder should be raised to a height that allows for a reach of 75 degrees from the ground, ensuring stability and preventing the risk of tipping.

By maintaining an angle of around 80 degrees when the ladder is fully extended, operators can achieve better stability and maintain operational control, which is critical during firefighting efforts and rescues. Proper ladder positioning is essential for minimizing the risk of accidents and ensuring that firefighters can access structures safely. The rule serves as a guideline for understanding the necessary angles to safely operate aerial apparatus, thereby enhancing overall safety and effectiveness during fire operations.
