How many sides of a structure should an aerial ladder ideally reach?

An aerial ladder should ideally reach two sides of a structure to provide effective access and versatility during firefighting operations. This allows for a better assessment of the scene and enables firefighters to engage from multiple angles, which is especially important for ventilation, rescue operations, and firefighting itself.

Reaching two sides helps firefighters not only to access the fire floor but also to create a potential escape route or provide additional support if conditions become untenable. This setup allows for more tactical options and can improve overall safety for both the fire crew and any occupants they may need to rescue. Additionally, having access to two sides can facilitate better communication and coordination among personnel working on the incident.
