Does your building have a smoke ventilation shaft?
Do you know for certain your building’s smoke ventilation shaft system operate safely?
RFC created this simulation to reconstruct an actual fire incident that occurred in a high rise residential building.
The video highlights the potential dangers associated with incorrect configuration / cause and effect of smoke shaft systems. As a result this system allowed the simultaneous opening of multiple floor vents (AOVs) to the smoke shaft.
Consequently the fire spread via the smoke shaft system to upper floors of the building and therefore breached the fire-resisting compartmentation.
Smoke control systems should be programmed such that only the AOV on the fire floor opens, all other AOVs should remain closed even if smoke is subsequently detected on other floors. This measure can prevent floor to floor smoke and fire spread via smoke control systems.
