What is the appropriate tip placement for a portable ladder to perform VEIS at a window?

When performing Vent, Enter, Isolate, and Search (VEIS) operations with a portable ladder, the appropriate tip placement is level with the window sill. This positioning allows firefighters to effectively access the window for ventilation and entry into the structure while maintaining safety and stability.

Placing the ladder level with the sill ensures that the firefighter can easily reach the window without having to stretch upwards or downwards, which could lead to potential falls or accidents. This position also effectively facilitates a quick and efficient entry into the building, maximizing the time it takes to begin searching and isolating the area. Additionally, being level with the window sill allows for better leverage and stability when venting smoke and heat from the structure.

This approach enhances operational effectiveness in emergency situations, ensuring that firefighters can perform their duties promptly and safely.
