Spreading of smoke without smoke removal
A fire breaking out inside a building always progresses in an entirely different way from an outside fire. The measures intended to provide preventive fire protection must take this fact into account. Every fire releases thermal energy and smoke. Hot smoke rises to the top and fills the room. Unless removed by appropriate means, the smoke in combination with the fire and hot gases will eventually destroy the building.
Spreading of smoke with smoke removal
Smoke and heat are discharged quickly by means of convection (heat dissipation) for the following purposes: minimise smoke formation along rescue and escape routes, guarantee full visibility for those trying to escape, i.e. save lives, prevent the “flashover” effect (smoke ignition), and facilitate firefighting operations by allowing the fire brigade to fight the fire in a quick and targeted manner, thereby preventing secondary fires and preserving property.
