Fire protection in public buildings
The sectorisation of fire is essential in any risk situation, wherever it occurs. The main objective is to keep the fire and smoke under control, preventing them from quickly expanding through the rest of the building. Thanks to sectorisation, risks are minimised in fire extinguishing tasks, allowing greater visibility and ease in accessing the affected area, avoiding the transmission of harmful smoke particles, reducing major structural damage, reducing subsequent costs, and allowing evacuation under the best conditions.
The sectorisation of fire in public buildings reduces the risk of people in the building being harmed by an accidental fire, as the buildings must be adapted to comply with basic requirements in case of spread of fire or smoke, taking into account the prior sectorisation of stairwells and the formation of hallways to connect different fire sectors in this type of building.
In case of fire, it is recommended to open the ventilators, deploy the fire curtains and smoke control barriers and use the extractors. The curtains limit the horizontal expansion of the smoke, redirecting it toward the ventilators, and help in the intervention of firefighters, facilitating proper ventilation in evacuation routes.
