In the event of a fire in a high-rise building, how many floors should be evacuated above and below the 'emergency floor'?

In the event of a fire in a high-rise building, it is recommended that the evacuation extends two floors above and two floors below the emergency floor. This guidance is based on safety protocols that take into account smoke movement, heat, and the potential for the fire to spread.

Smoke and heat from a fire can travel vertically, and evacuating these additional floors helps ensure that individuals are removed from areas where they could be exposed to hazardous conditions. Fire can easily impact multiple floors due to air currents and ventilation systems, meaning that those on the floors just above or below the incident may also be in danger.

When creating evacuation plans, such measures are crucial for ensuring the safety of occupants and providing a buffer zone to mitigate risks associated with fire spread. This two-floor evacuation recommendation aims to prioritize human safety and aligns with emergency response guidelines typically established for high-rise buildings.
