Where should the second due ladder be placed at a 3rd story fire in a 5-story non-fireproof building?

Placing the second due ladder at the floor directly above the fire apartment via interior stairs is a critical tactical decision in a firefighting operation involving a 3rd story fire in a non-fireproof building. This positioning provides several strategic advantages.

First, having a ladder on the floor directly above the fire apartment creates an immediate point of access for firefighters to conduct a potential rescue or to attack the fire from above. In many scenarios, accessing the fire from above can allow for better visibility and may give firefighters the ability to control the fire more effectively and prevent it from spreading.

Additionally, this placement offers a strategic vantage point for ventilation operations. Ventilation is a key component in improving conditions for both trapped occupants and firefighting personnel. By positioning the ladder one floor above, firefighters can assist in providing ventilation to release heat and smoke from the floor of the fire, helping to mitigate risks to both civilians and first responders.

Considering the importance of safety and quick access to multiple levels within the building, this choice optimizes the chances of effectively managing the incident while maintaining firefighter safety during the operation.
